I have lighting circuits turning themselves on but it is not showing on the log. Generally it is 2 separate dining units and the first four channels of a relay. There has been the odd circuit also. The Cbus line voltage is 30vdc. A power supply was added about 18 months ago Duse to low voltage. There has been no additional electrics added to the system. The clock was enabled on all units and has now been reduced to 3. There is a burden on the system. This has been changed. Not sure if it is associated but there is a circuit than sometimes flashes a single colour on the button and will not control the circuit until it stops
