Thanks, That IRIO01 seems a very useful future addition to consider. I'm proceeding with a mini 240V relay which allows me to get a reading without ...   Wednesday Sep 26th, 2018 08:59 pm

So, the current draw on the mains signal line is only 8mA (3mA idle). I'm going to struggle to get the CSM03 to read ...   Sunday Sep 23rd, 2018 05:33 pm

I have now tried all the possible combinations of Keypad and UCM connections with no change to the status. Soon after I apply 12V to the ...   Tuesday Dec 20th, 2016 04:12 am

Also, no cables are disconnected as the unit was working fine prior to the write.I have double checked these with no change in status. ...   Monday Dec 19th, 2016 11:42 am

Hi, Hope someone can assist with a simple fix... I wrote some updated responses to the system tonight and I am no longer able to connect ...   Monday Dec 19th, 2016 04:42 am

Many thanks This does indeed solve my problem - used a 'get counter value' to split cbus commands instead of the 'wait' function. ...   Friday Aug 14th, 2015 04:33 pm

Thanks Toni As the counters are mapped, I would have expected that this functionality would operate without a response as it does with dimmer control. I will ...   Friday Aug 14th, 2015 10:58 am

Hi I've just upgraded my UCM/CBUS unit to V2 (by replacing the CBUS plug-in) and am running V7.068 Most of the functionality is working as it should ...   Friday Aug 14th, 2015 10:53 am

Thanks for the response. yes, I have a backup battery. I had to remove the main fuse as well as the battery lead to reset the system. If ...   Monday Sep 29th, 2014 06:10 pm

I have a number of long range, external PIR's that handle external lighting and 'arriving home' scenarios. When installing the PIRs, I inadvertently shorted the power ...   Monday Sep 29th, 2014 01:55 pm

I have purchased my RPi as I was interested in developing something exactly along these lines. Please note that I am a beginner at this, but ...   Thursday Aug 2nd, 2012 09:51 am

I have a number of spare RIO inputs that I am trying to use as individual light switches (make sno sense to purchase expensive CBUS switches ...   Tuesday Jun 26th, 2012 08:06 am

Hi Julian I am very interested in trying out this software, but the links to your website are not working. Is there anywhere else I can download ...   Monday Jun 25th, 2012 08:41 am
