Hi Guys, \r\nI have been called up to have a look an old CBus v1 system (most devices are even showing on v1.0 firmware).\r\n\r\nThey have:\r\n - 2 x CBUS v1 - 4 channel dimmers\r\n - 1 x CBUS v1 - 4 channel relay\r\n - 1 x CBus v1 - power supply\r\n - 1 x Some form of clock device (part number 6000M1 written on it)\r\n\r\nThe call was to have a look at a single button switch that was intermittently not working. Thinking it was the switch since it is located in the bathroom I went to replace the switch. When i got on site I found that I was unable to reliably scan the whole network. Different devices would show up as "not responding" each time i run a scan. I tried to access the new switch on the network for over an hour but Toolkit was "Unable to identify" it even though I tried it on a test bench without an issue.\r\n\r\nI put my CBus tester on it and the network. The error on the tester keeps bouncing between "Add Burden" and "Remove Burden" every 3-4 seconds.\r\n\r\nI have seen many issues on these old systems where the power supplies look like they are working fine but are causing the cbus network to play up. I am not sure if this is one of those times.\r\n\r\nHas anyone else seen this sort of issue before?
