SOLVED

Hi, some time ago I installed lights in my office powered by the IKEA Tradfri LED Driver and switched over Home Assistant and ZigBee2MQTT with an IKEA Trradfri Switch. Everything worked perfectly for around 2 months and then the switch started to also switch the Aqara Smart Plug for my monitors. But only this one, the other Aqara Smart Plugs in this room are not effected.

Exactly the same happened in my living room, where I also have a Tradfri Driver, a switch, and an Aqara Smart Plug. There is no automation set up, that would have that effect, and I can’t find anything suspicious in the logs. The “fix” I found is to remove the switch completely and pair it again in Zigbee2MQTT. But then it only works for a couple of weeks as intended and starts the same, weird behavior again.

Has anyone an idea what could cause this and how I could debug it further?
