Does anyone know of a good alternative to the Xiaomi light sensor? I’ve got one and think it’s great for what I need, but sadly looks like they’re no longer available, at least for the good price that they were!
So just wondered if anyone has any alternatives that are as cheap as the Xiaomi was

Hue motion sensors report lux also.
Yeah cost puts me off them unfortunately 
Wifi or Zigbee?
I have one Tuya Wifi one which I reflashed with ESPHome and it works perfectly 
The rest (6 of them) are Aqara Zigbee ones which are excellent.
I use Aeotec multisensors (Zwave) that do motion, lux, humidty, temperature and more, all in one device. I run then from USB (but they can do battery as well), but this way I never have swap batteries and they report super fast.
Do you have a link to the aquara ones your using? Zigbee is my preferred protocol
