Early in the morning some of those lights turns on by a flow.
Later I turn all my lights with another flow that uses to turn on all 20 lamps.
But when that flow runs it turns of the lamps that already on.
What am I doing wrong ?
Does Groventre turn off immediately when you run the second flow to turn on all the lights, or does it happen some time after?
It almost sounds and look like you turn off the light in Groventre in another flow that you might not noticed or if that light only toggles. What kind of light is it?
Have you tried making a flow that turns on that light and test run that flow multiple times?
