Why are my lights randomly turning on for no reason? How do i debug this? (Zigbee/Aqara)

Configuration
1

So, i have been using HA for a while now, but recently i have moved to a new house and completely re setup everything. I primarily like to use zigbee where possible (i have about 100 devices and more slowly ready to be added).

I got rid of lot of the cheaper/crappier zigbee bulbs and now primarily running Aqara T1 and T2 bulbs. But since ive setup all the bulbs, im noticing that throughout the night, some bulbs that are off randomly turns them selves on (i use lights always only in groups and not individually, so when an individual bulbs turns on its fairly clear is not related to anything im doing).

Strange thing is, the light turning on is ONLY happening to my Aqara T1 bulbs. I primarily have Aqara T1 bulbs in the celing fittings and T2 bulbs in floor lamps - so either the issue is the T1 bulbs or the ceiling fittings. I have enabled power outage memory on ALL bulbs (i figured it maybe related to power fluctuations perhaps), and still no change.

I have turned off all related automations and this is still happening once in a while (its rare, but sometime i just wake up to have the hallway light on or bedroom light turned on etc).

Here is my setup:
HA running on VM (plenty of memory/recources) - latest
Zigbee2mqtt - latest
Zigbee Coordinator - smlight slzb-06

Any thoughts or ideas? It almost feels like someone has gotten into my HA and is trolling me, but then why isnt any T2 bulbs (which i have more of) not doing this?

PS: i do live in a fairly old house (but taken care of well and in very good state). its possible it has old wiring etc, but generally i have no other issues with the house otherwise.

Did you have them formerly running in a native app that is still talking to them?

That happens to us too with some sunricher in-wall relays. Annoying as fook.

Nope, always used with HA Z2M through that coordinator. I had deleted them and re added them. Keep in mind only SOME of the T1 bulbs are turning on, and some T1 bulbs so far seems perfectly fine. all T2 bulbs (new - got these very recently) are all perfectly fine so far.

Did you ever figure out what was going on? was there ever a solution?

Click the activity log in the left hand menu. There will be context for the light turning on if it was home assistant. e.g. turned on by automaton movement_light.

If there is no context then something outside home assistant did it.

Some devices will take their ‘default’ state when they loose connection, maybe that is what’s happening?

If so, a simple solution would be the reconfigure the default state to be ‘off’ :thinking:

At least in the past, Aqara and IKEA devices didn’t play nice together. The IKEA devices, by default, broadcast commands to groups that the Aqara devices, by default, happened to listen for.

You could try creating a new group in Z2M and add some of the T1 devices to it, to see if it stops them from behaving like this.
