Yes, a filter on zone or area would be excellent for my current research, trying to figure out why my entity-controller setup isn’t turning lights off. I would also be nice to be able to do a filter on group entities vs individual entities. Because my entity-controller is set up to activate groups of lights that are defined in groups,yaml not only do I see the groups being activated but I also see the individual lights being activated. It would be nice to have more or less granularity based on specific needs. Although I’m not a programmer, I would think the logic is fairly simple to do you look to see if the lights that appear are part of a group that also appears and you filter them out. This would very much simplify trying to figure out why lights are turning off when they shouldn’t and vice versa.
