I use deCONZ as home assistant add-on with the deCONZ integration. I have around 190 devices connected, and a quite stable network with many mains powered devices of all kind of vendors.
For some time now, I try to understand and hunt down why sometimes, lights, or more rarely, plugs, are switching on or off without an apparent reason. These incidents do happen sporadically, but do not follow any obvious pattern (at least I cannot recognize it).
Just now, the terrace light went on:
Nobody with exception of myself is at home. This device is not included in any automation. deCONZ logs indicate that just before the light was reported as “on” in HA (7 seconds before), the device sent a “DeviceAnnce” message (see below).

What could be the reason for this behaviour?
