So for some reason, I have a light bulb (matter device) that turns on by itself at the same time every night. First I swapped it with another new bulb of the same type but that did not work. Next, I deleted all my devices and routines and then did a factory reset on my hub (st v2). After re adding all my devices and recreating all my routines, the same thing keeps occurring. Has anyone experienced this before? I can see the event in the log every night, but I don’t know how to see what is causing it (a routine, another device, another paired service?) Any help is highly appreciated as this has been going on for many months.
If you use Alexa, check if Hunches is enabled and creating Routines in Alexa to turn on the light. Disable Hunches if that is the case and remove the Routines.
Nope, I definitely do not use Alexa. I do however have an Ecobee thermostat that has Alexa built in, but I have that feature disabled. Could it still be causing the problem?
No, if you are not using Alexa… nor added the integration between ST and Alexa… nor added the bulb to Alexa… then Alexa can be ruled out.

what is the brand/model on the light?
They are Linkind A19 RGBTW. I have eight of them running and this is the only one with the problem. And like I mentioned above, even swapped with a different physical bulb, but added to the same routines and location, it has the same problem.
Does that location suffer a power drop? If it shares a circuit with a large motor (freezer, heating system pump, etc.) it might reset and come back lit.
Debug by changing nothing but the circuit it’s on.
No it does not. And nothing else on that circuit loses power. I’m very certain something is telling it to turn on. It’s also very odd that it’s the exact same time each night.
A google suggests linkind has its own app and or an app aidot. It suggests its possible to have automations in that app, worth checking there ?

I loaded the AiDot app and there was only one device pre registered to my home, an item called OneButton, and it was default assigned to the bedroom, which is also the location of the light that is misbehaving. None of the light bulbs were registered because I just used them straight from the smartthings app. OneButton appears to be some sort of virtual or soft switch, best I can tell. I’m not sure how or why that device could or would be controlling any of my lights, but we will see if that was the problem tonight. I’ll report back.
If not using it can you delete the one button from aidot if confident it won’t cause problems?
I did, yes

I did have that same problem sometime last year, with a hallway light randomly coming on - and I still have the rare occurance of a smart plug randomly coming on once a month or so. Both are Tuya cloud devices, and the plug at least never had any automations whatsoever, anywhere, ever.
Now these link into SmartThings, and from there into Google Home and Alexa. So I’ve got three layers of possible culprits, and all of them pretend they didn’t do it, protocols are empty - and yet still, it’s happening.
Still happened again last night. I’m wondering, is it possible I didn’t get my hub completely factory reset properly, or that if this is caused by some type of data corruption, that it’s stored elsewhere like on a smartthings server, etc…
You can check Menu > History in the ST app to see if anything else happens at the same time. Anything Rules based will show up. That’s a quick check.
You could also install the CLI and monitor the driver logs when the bulb turns on to see if something is issuing a command, meaning an unknown app or automation is at work on the SmartThings side, or if SmartThings is just responding to the bulb being turned on outside of SmartThings.
However it doesn’t sound like SmartThings doing anything directly.
Given you know when the issue occurs, I’d be looking at swapping over two of your smart bulbs for that short period. No reconfiguration. Just the bulbs in different sockets in different rooms. If anything smart is happening the problem should follow the bulb.
Is the socket for the bulb controlled by an always on dumb switch?
Are any voice assistants about? They are more likely to be able to work with the label of a bulb rather than a specific device.
