I have suddenly started to get a Communication error with UCM2. My UCM2 is a zwave3 and has, up until today, been working fine. I reset the alarm as I had done a change to the programming and after resetting it announced the error.
I see RS485Comms, UCM#2 in red at the bottom of Comigurator.
I have removed the connector and put it on again, and reset again but am still getting the error.
UCM#1 is an Ethernet board and seems OK. I switched the RS485 connectors from UCM#1 to UCM#2 so that it was UCM#2 then UCM#1 but that hasn't helped.
I note the green LED is not lit on UCM#2 but is on UCM#1.If I scan for modules I get Not found for UCM#2.
Any suggestions as to what the problem might be?

Which green LED is not on in UCM 2?

The RDY LED turns  on if power is applied
The D10 Green Led flashes when it is polled by Ccmfort. Id 10 is offf, it means iit is not being polled. This is probably because The KA KB wires are not connected

The D9 red led flashes when the UCM replies ie communications is goood

Thanks for the reply.It is the green LED on UCM#2 that is not on, there are no LEDs lit on the UCM.The Ethernet daughterboard has a red LED lit.
I don't have KA KB connected as it is connected with the RS485 cable.

If no leds are on on the UCM it may be faulty, if you have tried powering off

Try doing a firmware upgrade using another UCM with the firmware upgrade cable

http://www.comfortforums.com/forum4/1782.html

Perhaps the firmware was corrupted

Tried - nothing happening :-(
It must be faulty. I'll get in touch with supplier Monday for a replacement.
When I fit a replacement will Comfigurator simply put all the z-wave devices back or am I going to have delete them all from the network and start again?

I do not think it is a problem with the 4 way cable. I moved the one from UCM#1 to UCM#2 and it was the same.
There is 12V at the terminal block marked 12V and COM

OK, request for a replacement UCMZwave
when you get the replacement, do a learn from the Primary controller so that the Zwave network has your new device
You will see the old UCM/Zwave Node which is now a dead node, which you cannot remove without the working device

Check that the mappings are correct and write to Zwave

Hi - things are progressing!  I received a replacement zwave UCM today and fitted it.  I did as you suggested and did a learn. Things appear to be working.  Now when I go to Exit Comfigurator it tells me the info has changed and do I want to write to the Eprom. I say yes and get a message, 'The HomeID & Node ID in the EEPROM differ from the values in the configuration = please read the EEPROM.  I read from the EEPROM and now have only the Primary controller listed. I exited Comfigurator without saving anything and reloaded.  Should I write to the EEPROM rather than read?
Also when I did the 'Learn' the primary controller found the new interface but Comfort didn't seem to learn anything. The command I used on the PC was 'Send Network Information to another Controller'.
The newly registered Cytech Controller is not appearing in the z-wave mappings.

Do another Learn on the UCM/Zwave. This should automatically Read from EEPROM. Save the cclx file
You should see the UCM/Zwave listed as secondary controller. The old UCM/Zwave may be there if you did not remove it from the zwave network using the primary controller
After doing the mapping then write to EEPROM
if you have problems send the saved cclx file to support@cytech.biz

Hi - I moved the aerial and had some success!
I'll play some more!

My next problem!  The nodes that were originally created as Virtual nodes in Comfort are now appearing as Basic nodes and as such don't have the options of a virtual node.   Is there any way to 'convert' them?

When you create Virtual Nodes in UCM/Zwave, these appear to the primary controller as "real" zwave nodes. They are virtual in the sense that they are in UCM/Zwave, but the Primary controller does not know that - it appears as normal zwave nodes

When you remove the UCM/Zwave without excluding the zwave nodes from the primaryt controller, the controller thinks that the nodes are still there, so they become dead nodes

When you add a new  UCM/Zwave, it wil learn the zweave network from the primary, and this will include the previous "virtual nodes" as normal nodes even though they do not exsti anymore. You need to add the virtual nodes again in UCM/Zwave and ignore the dead nodes

Alternatively, use the primary to reset to default and also reset to default all the zwave  nodes and start again. This may be a pain but it is the way Zwave works. If you are using all wave from a single manufacturer eg Fibaro they may have an easier way to manage it, but if there are other devices it can be nmore complicated

Unfortunately I am still struggling and any help you can give will be welcome.I deleted one of the previous virtual nodes that was now being seen as a basic node.I created a new virtual node (to replace it). The process started but ended with an error in the primary controller saying it failed to create correctly.
It appears in Comfigurator but is in the Primary controller without any info. I suspect I will have trouble deleting this at some stage but I'll worry about that later.
I have tried numerous times to do a Learn in Comfigurator but it sticks at 'Waiting for response from Z-Wave'. I know there is some communication because I see this in the Primary Controller;
Replicate Send started...
Activate the "Receive" function on the other controller while it is close to your HomeSeer interface...
A new node is being added...
Adding a new CONTROLLER...
DONE - Replication Send Operation is Complete.
Done. Node 45 Added.
Reloading (importing) node information...
Synchronizing node information with HomeSeer and creating new device(s) as necessary...
Synchronize nodes finished. Number of device nodes to be created/added = 0
Finished.

I have the same setup as I had with the previous board and everything worked as it should. I have moved the Z-wave USB stick so it is nearer the Comfort z-wave aerial but that doesn't seem to have helped.I'm not sure what to try next.

You say the the Learn operation results in Comfigurator. Can you save and send us the cclx file so we can see what appears

The learn data seems correct
Node 45 shows the controller in Blue which is the UCM/Zwave. Everything seems in order
I cannot tell why the primary has an error even when the UCM has copied the correct network from it This question should be asked of the Homeseer support

Have you tried controlling the Zwave nodes using the ON and Off buttons on each node? If this works then you should continue and ignore the primary controler errir

Everything is working fine in the Primary Controller, all the nodes that are not related to Comfort are working as they should.
I have visitors for a few says = I will have to leave this until they have gone!

Hi - had some time to look at this again.
I have now removed all the nodes originally created by the Comfort from the Primary Controller.
The Primary Controller continues to work correctly with all the nodes that are separate from Comfort.
I have tested communication from the Primary Controller and get a response;
Successfully sent a frame to node 45 (Node 45 Z-Wave Sigma Static Controller) which was acknowledged.

I did a rescan from the Primary controller and di spot a name change;
Successfully sent a frame to node 45 (Node 45 Z-Wave Cytech Tech Static Controller) which was acknowledged.

I have now attempted a 'Learn' again but nothing happens. The Comfort just shows 'Waiting for response from Z-Wave'.
The Primary Controller shows as per the attachment.

I now have the Primary Controller showing the correct nodes but Comfort showing the 'old nodes' now deleted from the Primary and I can't 'Learn the new configuration.

I've made some progress and can now set up new Virtual Nodes.

This, from another forum, helped me; "go into the Z-Wave controller menu and "Import Node Info from Controller and scan devices".

After doing this things seem to be as they should be, however I now need to try and recreate all the original nodes again and see if they work.
