While probably not addressing your core requirements, I see that you seem to have zigbee in your HA universe, I have been futzing around with a number of very low cost and long battery life Infrared lights that you can get using the zigbee Moes device cited in discussion below to control. As I said, probably not for your core, however there are a number of IR home assistant controls that might give you some more ‘bling’ 
We are having fun with the devices in the 2nd link and one of the zigbee moes devices outside (inside a waterproof transparent plastic food container) 
Good hunting! Happy Holidays!
