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?

So far the only inline option I’ve found is this dimmable switch from Samotech. I haven’t tried one yet myself, and there’s mixed reviews online. For the lamps I have I only want an on-off switch though, not a dimmer.

Making due with plugging them into smart plugs for now, but an inline option would be much neater.
