Simple problem: basement lights are on but nobody realizes it as the physical switch does not have a indicator light.
Simple solution: a Zigbee LED indictor that could be turned on or off depending on automation scripts.
There are a lot of Zigbee buttons out there but as far as I can tell non allows to control its status lights (if present).
I found this related thread from 2019 but no real solution.
For Zigbee to do that, the function has to be available in the interview or you would have to create a custom quirk to make it available.
I would look at espHome for that kind of thing, or just use a light group to clone the basement light state with a light upstairs. Like the light outside a walk-in freezer or dark room. HA can do this that way.
