Hi, ever since I installed my UCM/GSM4(3G) module last year I've always been convinced it doesn't quite work correctly when there is an AC power failure. Initially I assumed the local cell maybe also failed at the same time (although unlikely) and each time I have a power failure there seem to be some missing SMS messages but I never get around to investigating further at it works normally again after that. "Normal" means that various zones trigger SMS messages and I also use various Control menus via SMS. However, this time, the first power failure for 7 months happened when I'm away (we normally get ~1 power cut per month on average). Comfort dialled me via Landline and reported a power failure. I did also receive one Power Fail and a Power Restore SMS message but then the power went down again for a couple of hours. Now that power is back I can dial-up comfort via the landline and that is okay but it is refusing to respond to SMS texts and if I phone the SMS module it answers (with silence) and then disconnects. I've managed to get a VPN connection and retrieve my event log and I can see various failures where it tried to send me other SMS messages about power failure and restore but more worryingly I can see various events that I don't understand: "SMS Dial Failure #89" events and also 98 /99 / 100 / 16 at various points and also "SMS Trouble ID # UCM 2" and "SMS Restore ID # UCM 2". From the Comfigurator "Get Status" mechanism I can see in the toolbar that UCM status of the GSM Module is showing that it does have a good network signal and then the status message status "Normal/No error". Anyone got any ideas? |

The event log should show the dialing attempt as well the successful acknowledgement of the SMS by the mobile network provider egDial Number #3 means there was a dial out to phone 3. This may be Voice Phone or SMSIf the selected phone is an SMS Phone Type then the next event should be "Remote Signin - User # SMS Acknowledge". That shows that the message was deleivered, not that you received the message, as there may be delays through the SMS network. If the SMS fails to send there should be "SMS Dial Failure". Comfort will resend up to 5 times . SMS Dial Failure #89 - you can ignore the #89 or other numbers. The evemt log listing has to incliude a number parameter but in the case of SMS Dial Failure a random number appears. So just treat them as SMS Dial Failiure. We may change that in the future version of Comfigurator 05/15 17:49 Mode Change # Away Mode 05/15 17:49 Dial Number # 3 05/15 17:49 Remote Signin - User # SMS Acknowledge 05/16 07:31 Zone Activation # StoreMainDoor (33) If you dial the GSM number and there is silence, it could be that the 5 way audio cable was not connected betwen the GSM and Comfort PCB in the first place. I wonder if you have tried to dial before? Try a remote reset from Comfigurator using Transfer > Reset System |

Hi, I've used the voice dial-in to the GSM module before so it's unlikely to be a cable fault. Looks like everything returned to normal about 3:30am so at least it is working now. I saw a couple of the "SMS Acknowledge" events that you mentioned for when it did initially text me - I assume they only get set on dial-out activities and not for custom SMS message sending as I don't see them anywhere else in the event log? If I ignore the 2 digit number on the end of the SMS Dial Failure messages then all I see in the log for a while is repeats of those plus these two messages: SMS Trouble ID # UCM 2SMS Restore ID # UCM 2 I've connected this morning and downloaded the event log again but there is nothing new since my forum post last night and nothing around 3:30am when the custom text messages suddenly got sent. So, perhaps it was due to the local cell partially failing since the SMS module did say it had a good network signal. If the "Trouble" messages above don't give any clues then I will have to do some specific power fail tests when I get back. |

Yes I believe that it was a failure of the SMS provider to send messages even thpough the signal was good Send SMS messages is not recorded in the event log as it is not considered to be an alarm event |

Hi, over the recent holiday period I had another incident related to my above issue (SMS messages not always sent during/after power failure) and this leads me to believe it is definitely a Comfort bug. My system is configured to send custom SMS messages in the event of a power failure and should also send a standard Power failure alarm messages. The behaviour I saw was as follows: We had a power failure at 3:45am 22nd December when the system was in night-mode. I got out of bed to sign-in and acknowledge the power-failure alarm. We received no SMS messages at all (standard or custom). Messages were not received by either my mobile or my wife's (two different mobile network providers). A few minutes later (~3:48am) I sent a custom Control SMS to Comfort and I successfully received a reply, so it was still sending those types of SMS test messages okay. As I've always had unreliable Comfort SMS issues around power failures I thought nothing of this until a few days later. On the 27th Dec I accidentally triggered an Intruder alert in Night Mode late in the evening. Both my phone and my wife's then received several standard SMS messages about the power failure from 5 days earlier, plus a text about the Back Door being opened (i.e. the cause of the alarm in Night Mode). I'm not sure why the event log also such a lot of "Remote Signin - User # SMS Acknowledge" messages? So, since Comfort had sent lots of other custom SMS messages in the meantime (e.g. every time my gate opens) this implies that Comfort must have had these standard Power Failure alarm SMS messages stuck in some sort of internal queue and the intruder alarm condition caused it to flush this queue. If so, that must be a bug? The custom power failure/restore SMS messages still never did arrive. I have other custom responses that send SMS messages in the event of non-intruder alarms like Line Cut/Restore and they seem to work okay (and we have had a lot of line cuts due to broadband fault repairs). Another odd thing also occurred with this intruder alarm: I had missed the phone call from Comfort (on my mobile) but I was pretty much immediately signing in on the Comfort keypad to cancel the alarm. It announced “Back door†(which was the contact that had triggered) then there was a very long silence, perhaps as long as 60 seconds, or more, then it eventually announced “Security offâ€. That also seems very odd. I've pasted the relevant parts of the event log below and also attached a picture of the messages received. Can anyone see any issues? I could send my config by private message to Cytech if this will help investigation. 12/21 23:18 Sign in - User # Keypad 12/21 23:18 Mode Change # Night Mode 12/22 03:44 AC Fail 1 12/22 03:44 Send SMS Custom Message # 3 ["Powercut Detected" message] 12/22 03:44 Dial Number # 2 12/22 03:44 Send SMS Custom Message # 6 ["Power Restored" message] 12/22 03:44 Dial Number # 2 12/22 03:44 AC Restore 1 12/22 03:44 AC Fail 1 12/22 03:44 Alarm Type # PowerFail (8) 12/22 03:44 Send SMS Custom Message # 3 12/22 03:44 Dial Number # 2 12/22 03:44 Send SMS Custom Message # 6 12/22 03:44 Dial Number # 2 12/22 03:44 AC Restore 1 12/22 03:45 Sign in - User # 1 12/22 03:45 Sign in - User # 1 12/22 03:45 Mode Change # Security Off 12/22 03:45 SMS Dial Failure # 12 12/22 03:45 Sign in - User # Keypad 12/22 03:45 Mode Change # Night Mode 12/22 03:45 SMS Dial Failure # 12 12/22 03:45 SMS Trouble ID # UCM 2 12/22 03:45 SMS Restore ID # UCM 2 12/22 03:46 SMS Trouble ID # UCM 2 12/22 03:46 SMS Restore ID # UCM 2 12/22 07:25 Sign in - User # System Response 12/22 07:25 Mode Change # Security Off ... 12/27 23:13 Sign in - User # Keypad 12/27 23:13 Mode Change # Night Mode 12/27 23:26 Alarm Type # Intruder (1) 12/27 23:26 Zone Activation # BackDoorContact (1) 12/27 23:26 Restore - Zone # BackDoorContact (1) 12/27 23:26 Dial Number # 1 12/27 23:26 Remote Signin - User # SMS Acknowledge 12/27 23:26 Dial Number # 2 12/27 23:26 Sign in - User # 1 12/27 23:26 Alarm Type # AlarmAbort (20) 12/27 23:26 Sign in - User # 1 12/27 23:26 Mode Change # Security Off 12/27 23:26 Remote Signin - User # SMS Acknowledge 12/27 23:26 Dial Number # 3 12/27 23:28 Dial Number # 1 12/27 23:28 Remote Signin - User # SMS Acknowledge 12/27 23:28 Dial Number # 2 12/27 23:28 Remote Signin - User # SMS Acknowledge 12/27 23:28 Dial Number # 3 12/27 23:29 Remote Signin - User # 2 12/27 23:29 Remote Signin - User # 2 12/27 23:29 Dial Number # 1 12/27 23:29 Remote Signin - User # SMS Acknowledge 12/27 23:29 Dial Number # 2 12/27 23:29 Remote Signin - User # SMS Acknowledge 12/27 23:29 Dial Number # 1 12/27 23:29 Remote Signin - User # SMS Acknowledge 12/27 23:29 Dial Number # 2 12/27 23:29 Remote Signin - User # SMS Acknowledge 12/27 23:29 Dial Number # 1 12/27 23:29 Remote Signin - User # SMS Acknowledge 12/27 23:29 Dial Number # 2 12/27 23:29 Remote Signin - User # SMS Acknowledge 12/27 23:33 Sign in - User # Keypad 12/27 23:33 Mode Change # Night Mode Attachment: Mobile messages received 2018-12-27.jpg (Downloaded 72 times) |

It would be helpful to send your cclx file and event log to support@cytech.biz so we can check.Your custom power failure messages were never sent but the standard power failure mesages seem to be stuck behind the custom messages so there may be a problem with the custom power failure message "Remote Signin - User # SMS Acknowledge" means the SMS was delivered successfuly to the network. If this does not appear after "Dial Number #" that means the SMS was not successful perhaps due to network issues. Comfort should re-dial "Remote Sign-in User N" means someone signed in to accept a call to voice phone. If this is not seen then the usert did not acknowledge or sign in, and Comfort should redial The delay for announcing security aff after you disarm on the keypad while is it dialing out should be due to Comfort terminating the outgoing call and doing its housekeeping |

Ok, I will email you my config file now. Thanks for investigating. |

It looks like the problem is because in the Power Failure alarm, you have set dial out to several SMS numbers, but you have also an Alarm Response to send the custom message This is causing a conflict causing one of them not to get sent out The power failure alarm set to SMS Phone dial out will send the SMS message to the programmed phones, so you do not need a custom SMS message, as that will be duplicate You can either disable the Alarm Response and allow the Power Failure alarm dialout, or disable the Dial out to the SMS phones in Power Failure alarm. We will investigate why the sms message is suppressed when you select both methods of sms dial out Last edited on Monday Jan 7th, 2019 05:46 am by slychiu |

Ok, I'll do that for now as a workaround but I think I only added those custom SMS messages last year when I originally had issues with the standard power fail SMS messages regularly failing to work. |

It seems that the Custom SMS messages may interfere with the alarm sms messages if they occur at the same time. We wiill look at how to make them work better together |

Any news on a firmware update for this yet? I removed my custom AC failure messages. I had an AC power failure today but received no standard Comfort SMS messages whatsoever. Comfort phoned me and I signed in (AC had already restored by this point), I can see those events in Event log and then a few minutes later I see it attempt to "Dial" other numbers, presumably to send standard SMS messages, and I see SMS Dial Failure #16 and #99, but I thought you said those were to be ignored? I then see SMS Trouble and SMS Restore a couple of mins later again, and a few more SMS related events after that too, but no actual texts. It just feels like something is still wrong with Comfort's logic/config here? |

Can you send the actual event log after the power failures? Dial failure means the message was sent to the mobile provider station but it was not delivered for some reasoncan you repeat the power failure test? |

Hi, yes, sorry. Below are the actual event log entries. Please note that I later realised I had actually received two AC failure related SMS messages (not sure how I missed spotting them the other day), one for the failure, one for Restore. However, there is still something not right as both text messages were delayed by 5 minutes and did not arrive until 13:43, which seems to align with the repeated Dial Failures below. Yes, I can also try and simulate a power failure again if needed. 04/25 13:37 AC Fail 1 04/25 13:37 AC Restore 1 04/25 13:37 SMS Trouble ID # UCM 2 04/25 13:37 Dial Number # 3 04/25 13:38 Remote Signin - User # 2 04/25 13:38 Remote Signin - User # 2 04/25 13:38 Sign in - User # 2 04/25 13:38 SMS Restore ID # UCM 2 04/25 13:38 Dial Number # 1 04/25 13:39 SMS Dial Failure # 16 04/25 13:39 Dial Number # 2 04/25 13:39 SMS Dial Failure # 99 04/25 13:40 Dial Number # 1 04/25 13:41 SMS Dial Failure # 16 04/25 13:41 Dial Number # 2 04/25 13:41 SMS Dial Failure # 99 04/25 13:42 Dial Number # 1 04/25 13:43 SMS Dial Failure # 16 04/25 13:43 SMS Trouble ID # UCM 2 04/25 13:43 SMS Restore ID # UCM 2 04/25 13:43 Dial Number # 1 04/25 13:43 Remote Signin - User # SMS Acknowledge 04/25 13:43 Dial Number # 2 04/25 13:43 Remote Signin - User # SMS Acknowledge 04/25 13:43 Dial Number # 1 04/25 13:43 Remote Signin - User # SMS Acknowledge 04/25 13:43 Dial Number # 2 04/25 13:44 Remote Signin - User # SMS Acknowledge 04/25 13:46 SMS Trouble ID # UCM 2 04/25 13:47 SMS Restore ID # UCM 2 04/25 13:53 SMS Trouble ID # UCM 2 04/25 13:54 SMS Restore ID # UCM 2 Then nothing after this for a few minutes at which point everything is normal again |

As there are many SMS Trouble and Restore I would check the GSM signal strengthIt is shown in the left bottom in the UCM/GSM4 window The signal could be dropping out, so the SMS is sent when it recovers. We have a high gain antenna which improves the signal level |
|||||||||

I've looked at the signal in the past and it is always good. My Comfort system regularly SMS messages throughout the day when it notifies me of gates opening & closing. I never have any issues with those messages, they're always received within 1-2 seconds, and there is also a back-up Gmail message (sent at the same time by a different system) so I'd know if the Comfort SMS messages were ever delayed. I only ever get issues with missing Comfort SMS message around power failures. |

"SMS Dial failure" in the event log means that the UCM/GSM sent the message to the GSM network, but it failed to be accepted. The reason for this is not known.However Comfort will repeat the attempt 5 times until it gets an acknowledgement that it was accepted ie "Remote Signin - User # SMS Acknowledge" There were 3 rounds of attempts to phones 1 and 2 until the next try succeeded - that is why there was a 5 minute delay I am not sure why this happens with power failure. We will do some testing |

Hi, has there been any progress on investigations of this? I had another power failure last night and had similar problems. I did receive a call from Comfort (via landline) but received no standard SMS AC Failure notifications.Power was off for ~35 mins. During this time I was unable to get any response from any SMS control messages that I sent and making a voice call to the GSM Module immediately cut off. I DID receive an AC Restore SMS about 10 mins after power was restored. I also noticed a new issue - when I made a call to Comfort's landline during the power outage it took about 25 rings before Comfort voicemail answered even though it is configured to answer after 8 rings. This is very odd and was as though Comfort was just too busy stuck with its CPU processing something else (maybe failing to send SMS, or GSM module issues?). Also, I noticed that even 25 mins after AC power was restored I could still NOT get the Comfort GSM module to answer a voice call. I tried twice but it just immediately hung up after a single ring. I know the GSM modue was partly working though as it was now answering SMS messages again. I tried again a voice call to the GSM module couple of hours later and it was working normally again. This is very annoying and I'd really like Comfort to work correctly when there is a power failure. Do you have any ideas? |

Can you turn off your AC power, ie make a POWER faiure Check the status bar in the UCM/GSM Module screen . \It should show the GSM signal strength what is the signal strength shown? Turn in the power, and check what is the signal strength |
|||||||||
|
slychiu Administrator

It is better totry the following. with AC on,Get on the UCM/GSM modules tab ad check that the GSM signal strength on the bottom left status is normal ie 2 to 4 Turn off the AC and check what happens to the signal strenth on the status bar. does it disconnect and try to reconnect wait for it to revonnect to the network. if it reconnects, try the sms and call in Turn on the AC agaibn and checj what happens to the signal strength |

I think I did do that in the past but I will do it again. I think I only pulled power to my main panel though (which has the GSM module) and not the separate supply to my SEP panel. You could imagine some quirky behaviour if both lose power, or something like that. I will try and also disconnect the network cable from the ETH module as when I lose power that would also effectively lose it's connection, just in case that makes any difference. I'll report back in a few days... |

Do not disconnect the ETH03 as that would mean we would not be able to monitor the GSM status The battery shpuld powere up the Comfort and UCM modules, they should not lose power |

yes, okay, good point. I just meant as an optional test (after I've checked signal levels etc) to see if that's the trigger for making the GSM module start to fail |

Hi Slychiu, I haven't got around to doing a controlled power failure test but I was at home today when we had a 45 min power outage so I did some checks during that power outage: During the full power failure, my network switch and wifi were on UPS now so I eventually (*see below) got Comfigurator on my laptop to show the GSM4 UCM GSM network signal status. It showed "Good - 3" as the network strength but I had NOT received a power fail SMS text message. When the AC power returned after ~45 mins, a few minutes later I did then receive a Power restore SMS message. Also, when the AC was restored I then immediately checked the signal strength again and it showed "Fair - 2" and texts are working normally. I never miss one under normal circumstances. So, I'd say this seems to show that the fault is very likely with Comfort. I can still do a controlled test power failure (i.e. Comfort main panel only) if needed, but the fact that the GSM module claimed to have a good signal strength does point a Comfort bug somewhere. * I think there is a minor Comfigurator bug/quirk - if you launch and open the config, navigate to the relevant GSM4 Module and click "Get Status", it asks you for the PIN to login, but then does not immediately show the status. Trying again now I think it puts you on to a different page and you have to navigate back to that page, but maybe I did not notice that earlier during the power failure. Also, when I was in power fail situation, the "GSM Network Strength..." message appeared in red for a couple of seconds and was then replaced by "Normal/No error" in black and no mater how long I waited the signal strength message didn't reappear without me navigating away from the module and back again. Now I'm in AC-okay mode, it still does mostly stay on "Normal/No error" but does regularly (every 30 seconds or more?) switch to the signal status message, but still only for a couple of seconds. Not |

We have bot been able to find any problem with diak out during power failure Please upgrade to GSM4 7.128 Beta firmware which has some improvements in operation which may or may not have an effect on your probelmsfrom http://www.cytech.biz/product_details.php?item_id=227 |

Ok, thanks, I'll download and try that over the next week or so and let you know. Before installing the new firmware, I will still try and do the manual controlled power failures (of my Comfort main panel, and SEM01 panel) as they are on different circuits within the house, just so I have that info to help with the diagnosis too |
|||||||||

caravanboy Member

I did some manual power failure tests as follows but all worked as expected: 1) Power fail on main panel - official Comfort SMS received OK, voice call OK, test SMS worked during power failure, AC Restore SMS worked ok. 2) Power fail Slave panel only - no Comfort SMS (as expected), test SMS worked during power failure. 3) Power fail Slave, then power fail main panel (approx. 2 mins later) - official Comfort SMS received OK, voice call OK, test SMS worked during power failure, AC Restore SMS worked okay. So, I just need to remember how to upgrade firmware now as I've not done it for a couple of years. Comfigurator only seems to offer me a "by cable" option. Hmm I guess I can then just have the latest beta GSM4 firmware installed and wait for the next full power failure. Perhaps the issue is caused only when the main and slave panels fail at exactly the same moment? |

Hi Slychiu, As mentioned above, I upgraded UCM/GSM4 to 7.128 a while ago but that did not show any noticeable improvement on this behaviour – the AC Fail/Restore SMS messages rarely arrived promptly after a power failure, although I did not have as many outages as usual in the last year so I didn’t get back to looking into this. About a month ago I upgraded my system to the most recent firmware for all components (Comfort, Slave and UCM/GSM4 etc). Yesterday was the first power outage I’ve had since being on the latest firmware but I’m sure there’s still something not right… We had a power failure at 8:20am for around 10 seconds. I acknowledged this from the keypad (to stop the warning beeps) and then also received a call to my mobile which I acknowledged. I did not receive any SMS messages until 7 minutes later and their contents showed they were generated at 8:27:54 and 8:28:04 for the “AC Fail†and “AC Restore†respectively. By the way, it is nice to see that the newer firmware has added the seconds in to the message times. I checked that Comfort’s time is still accurate so those messages were only generated by Comfort about 7 minutes after the power outage. Relevant items from the event log still show some sort of initial SMS Trouble and then an SMS Restore (8:21am) but then repeated failures to send after the SMS Restore, before the AC Fail and AC Restore messages were eventually sent to both my phone and my wife’s. This is very similar to the behaviour we saw back in April 2019 (on this thread) when the failures continued after the SMS Restore. You can see from the other tests I did a while ago (Jan 2020) that when the power has failed Comfort still show the signal strength of the cell is okay. Do you have any further suggestions or ideas of how I can investigate this further? Event log shows this (also nice to see that the misleading/confusing Dial Failure error number has been replaced with a zero): 05/03 08:20 AC Fail 1 05/03 08:20 AC Restore 1 05/03 08:21 SMS Trouble ID # UCM 2 05/03 08:21 Sign in - User # 2 05/03 08:21 Sign in - User # 2 05/03 08:21 Dial Number # 3 05/03 08:21 SMS Restore ID # UCM 2 05/03 08:21 Remote Signin - User # 2 05/03 08:21 Remote Signin - User # 2 05/03 08:22 Dial Number # 1 05/03 08:22 SMS Dial Failure # 0 05/03 08:22 Dial Number # 2 05/03 08:23 SMS Dial Failure # 0 05/03 08:23 Dial Number # 1 05/03 08:23 SMS Dial Failure # 0 05/03 08:24 Dial Number # 2 05/03 08:24 SMS Dial Failure # 0 05/03 08:24 Dial Number # 1 05/03 08:25 SMS Dial Failure # 0 05/03 08:25 Dial Number # 2 05/03 08:25 SMS Dial Failure # 0 05/03 08:26 Dial Number # 1 05/03 08:26 SMS Dial Failure # 0 05/03 08:26 Dial Number # 2 05/03 08:27 SMS Dial Failure # 0 05/03 08:27 Dial Number # 1 05/03 08:27 Remote Signin - User # SMS Acknowledge 05/03 08:27 Dial Number # 2 05/03 08:27 Remote Signin - User # SMS Acknowledge 05/03 08:27 Dial Number # 1 05/03 08:28 Remote Signin - User # SMS Acknowledge 05/03 08:28 Dial Number # 2 05/03 08:28 Remote Signin - User # SMS Acknowledge |

SMS Dial Failure indicates that the SMS was not accepted by the SMS provider. The reasons are not clear Are the dialout to Voice phone at #3 also my GSM or is it by phone line? |
|||||||||

caravanboy Member

Hi, dial out 3 was by phone line. As I've mentioned before in this thread, during power outages the GSM module has a good signal and my SMS messages are sent many times per day (when a gate opens) and they never fail. I cannot understand why the SMS messages fail to send from Comfort only when there's a power failure even if the signal strength is good. This does point to it being a quirky bug with Comfort. Any suggestions on how I can help investigate further? |

I'm still having issues with SMS messages after power failure. This time I have more evidence that the issue seems to lie with Comfort... Power failure was at 00:09 - you can see in the event log that it went on and off a few times over several seconds before then staying off for almost 3 hours. After the first AC failure Comfort then logged "SMS Trouble" that we've seen before in previous postings in this thread. HOWEVER, it also logs an "SMS Restore" very shortly afterwards at 00:10. At 01:05 I dialled-in to Comfort on the GSM number (instead of landline) and got silence (a separate issue that was only resolved a few days later after a reset) and did not realise it had answered and was actually recording a voicemail. But this DID prove that the GSM module was alive and well and able to send texts as I did then receive a "New voicemail" text immediately (the custom message #4). At 03:00am when the power finally came back on we started to receive the Power Fail/Restore texts that should have been sent at 00:09. The bodies of the text messages had Comfort times embedded in them ranging from 03:00:56 to 03:02:36. This presumably indicates that Comfort only decided to create and send them at that point (i.e. they had definitely NOT been stuck in the GSM network). Any thoughts on how to investigate this further, slychiu?

Ahh, this is great. Makes me feel a little better - I did just assume there must be some unknown setup/config issue with my system  I'll look into the linked information.However, I changed my SIM and GSM network provider a few months ago and since then I've had a couple of power outages and the SMS messages re. power failures have worked perfectly. I guessed that perhaps my old provider had a borderline signal (despite it showing "Good" when on AC) and wondered if perhaps when on battery Comfort wasn't providing enough power for the SIM to make reliable contact with the cell tower? Anyway, assuming my theory was rubbish, could this problem that you've identified only happen with some providers/SIMs, and might explain why my new SIM works okay?

We have been using various gsm modules in the office and have never had the problem even after AC Off. This particular customer informed us of the problem and allowed us to access the system remotely and check signal level and event log. Thus we noted that after power failure the sms failed to send. This was fixed by a reset of the module. It also happened after power restore. I agree that it could be due to a network providers signal. I dont believe it is due to battery not being able to supply the GSM becayuse after a reset you could asend SMS again. It is probably the voltage drop or a noise interference during power off and restore. |
