This seems like an edge case. It’s pretty rare to see a product advertise a protocol that isn’t freely used like this one. It even explicitly says in the product description it requires a hub. Aqara has always played fast and loose with support of various open specs.

Ecobee remote thermometers use Zigbee, but they can’t be generally paired to non ecobee products, and as such they don’t advertise Zigbee support.
