Currently, with device groups, if the group state is currently on, turning on another device within the group doesn’t trigger a state change/update and therefore can’t be used to restart an automation timer.
My use case is this. I have a hot water circulation pump that is triggered on for 30 mins whenever a shower light is turned on. For a single user, this works fine now, but if multiple people start a shower, the pump shuts off 30 mins after the first user started, regardless of when the second user started. I want the shower light group to be able to retrigger the timer anytime a member light is turned on.
