I have a group of lights that are turning on and I dont know why. Is there a way to determine what triggered them to come on.

When you open the light, the right button t the bottom will tell you when it was switched n by what flow

If that does not work you can add logging cards to you flows using [papertrails](https://homey.app/en-us/app/nu.dijker.papertrails/PaperTrails-Log/) or setup logging via [audit](https://homey.app/en-us/app/com.audit/Audit/)

Yeah I am using the groups app to group my light and control them so it make it hard to tell what is going on from the device timeline
