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.
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.
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.
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.
Sorry i completely missed the previous couple of replies. Thank you for your suggestion. Could you please explain what you mean by creating a group?
I have created a group in Z2M and added two T1 bulbs (two bulbs from my hallway - these two tend to turn on randomly quite often). What does this do? I havent done anything other than adding the bulbs to the group. Do i need to do something with the group somehow? I feel like im missing what these groups supposed to do haha.
Problem is, i assume activity log only displays very recent logs. This light turning on thing happens infrequently enough that i can never go into activity log or logs in general to search for it - nothing show up.
I wish this was happening in my office, it would be super obvious and i could jump on HA immediately to check logs, but sadly no.
I can reassure you that no automation is causing this behaviour 100% sure.
That said, in HA device settings activity log on the right side does show the light turning on (and if it was turned on by automation, it would say that here). However, it simply just displays:
In theory if this was possible, if i set default to Off, then i would have the reverse problem haha - not sure what is worse.
That said, i dont see any option for default state Off. However, since when i made the original post, i had turned on “Power outage memory”, meaning that when power turns off and on, the light will retain the previous state (this part works, i can test by turning off and on the wall switch). However, it hasent helped, the light still turns on randomly.
Ahhh, oops. That is helpful, but it looks like it shows the same information that gets displayed on the right when you go into the device it self. That said, this is all i see on the logs:
Not Aqara, so take this worth a grain of salt, but when I had a Philips Hue outdoor power supply that was failing, the light connected to it would turn on by itself randomly.
So it is possible the devices are failing or there is some other transient power issue.
Have you tried:
Moving the problem bulbs to a different fixture on a different circuit?
Swapping in a known working bulb from another fixture?
Zigbee groups in general are basically what it says on the box: a group of devices. A group has a unique identifier, and when you want to turn on the devices in a group you can send a single message directed at the group, instead of having to send an individual message to each device.
Adding a device to a group is basically telling it that “hey, from now on, you should listen to messages directed at group id X”.
Both IKEA and Aqara devices, and possibly other brands as well, listen to a particular group id by default (or at least they used to). This is done to make certain things easier, but the manufacturers assumed that nobody in the world would use any other brand of devices in their Zigbee network. And so, interference between brands was born.
By adding the Aqara devices to a new group, my hope was that this would make them stop listening to the old group, and fix your problems. You don’t have to do anything with that group.
