I am looking to create a sensor for each room that would turn on if one entity is on out of a list of specific devices. Someone suggested using groups but I have both light and switch entities so that won’t work.
Does anyone have any suggestions or a link to set something like this up?
@tom_l 's way works as well. I just removed all my old legacy groups and recreated them in the UI so I didn’t want to go that route or convert entities.
