I am having a T1M ceiling Light installed for a few months now.
Since day one I’m experiencing a strange behaviour. One or two times a day the light turns dark, and instantly slowly fades back up again.
The Lamp is only connected via a Zigbee Stick to Homeassistant. There is tried to reset the Lamp, reconfigure, update and all that. I also tried to turn the transition time to 0, as a bandage, but this also won’t work. Since it happens so rarely, its hard to troubleshoot, change things and see if it works.
To add to this: this is the second Lamp I installed in that place, since the first had a different defect and needed to be replaced. The first Lamp showed the same behaviour.
If there’s no stray automations that could be causing it and a previous light in the same place showed the same behaviour it does sound like a potential wiring issue, as if the current/voltage is dropping.
Hi there!
I can confirm this behaviour, I have two Aqara T1M ceiling lights from 2 momths now.
Same thing, randomly 1-2-3 times a day both lamps blinks… Goes dark, and instantly fades back.
I can guarantee that there is no voltage/current drop, I do have sensors for that. It is some firmware issue perhaps?
Both are connected to direct main, no switch.
At the first days one of them wasnt even connected to Bridge, and it was doing the same.
Current setup:
ZHA With HomeAssistant Green + ZB Dongle-P.
