hello, my Cbus program got burnt out. The track lights randomly switch on and off. Got an electrician to come and fix and re programme switches. It costs 650AUD. But then one month later, the lights are blinking in the lounge room and 1 bedroom and the same electrician came and said the light dimmer is found to have problem. He said the dimmer can't be separately removed and can't be reprogrammed to disable the dimmer. And replacing the dimmer cost 00. Can anyone help to see whether the above diagnose make sense and any recommendation of a good CBus specialist in the Sydney city area?
