I had to comment out my TV and Logitech Hub because they would randomly turn my tv on at night.
I’ve looked through the logs, and all I see is that it turned on, but I do not see why it’s turning on. I’ve gone through my automations, and there’s nothing that appears to be effecting anything in my living room. It does appear to be linked to my living room motion sensor somehow, but I’m not seeing a connection anywhere.
If you aren’t using it for an automation, I wouldn’t worry about it too much. You could exclude the group from the logbook if you don’t want to see it.
The default behavior of a group is that if any one of its members turns on, then the group’s state becomes on.
There is an option available to alter that behavior. If you set all: true then all members of the group must be on before the group’s state is set to on (see documentation).
The choice depends on what you intend to do with the group.
The groups can be used multiple ways. I have groups for my door and window binary sensors that trigger my alarm control. I also have groups that are only there to group similar items together, like 2nd day weather items that include temperature, humidity, and pressure.
The odd thing is though, is that it didn’t turn on any of the lights, just the TV. Oh well, I’ll just leave the group commented until I need it for something
