How to handle lights that are physically powered off (but Home Assistant still sees as "on")? (startrek.website)

I have a button that triggers a script for bedtime to turn off all lights, and, if pressed again, checks to see if all lights are off and if so, turns a few (like the bathroom light) on.

My problem is one or two of the lights (connected via Zigbee2Mqtt) are often powered off at the switch on the lamp, meaning HA still sees them as "on" until the power is restored and they can be turned "off" via the app. The lights cannot be turned "off" (in HA) manually.

Is there any good solution for detecting when a light goes missing and turning it "off" in HA?

Disable or remove the lamp switches. Add more smart buttons if there is a need for a physical control near the lamp.

As it happens I’m actually looking for a smart lamp switch if anyone knows of any options.

    I was doing the same myself earlier this year. I'd found a European product that was an inline smart switch, like one of those rocker switches they put on the wire for those decorative canister uplights. The switches were out of stock on all the sites that listed it, and the manufacturer website didn't seem to indicate they'd be producing more any time soon.

    Eventually I just settled on using an inexpensive smart button (Tuya TS0041/TZ300 over ZHA) to control a smart bulb or a smart plug on the "dumb" fixtures. It wasn't exactly what I wanted, but nobody seems to make a smart inline switch anymore. As a bonus, the switch supports double-tap and long press gestures so I was able to program the bedside button with a few functions to toggle the bedside lamp on a short press, and turn off all the lights in the house on a double tap.

    It uses a coin battery that lasts a few months. I think I've changed it maybe once since I got it.

    They should just enable offline/online detection (edit: the z2m setting is called availability)

    I’d say it’s always best to avoid Zigbee devices going offline, its neither convenient for automation or good for the mesh for devices to keep dropping.
