This is a great product, where every other network attached zigbee hubs needs cloud access, this dont! So this is one of the very few 100% privacy oriented zigbee hubs, and with zigbee2mqtt you can use as many of these as neccessary with Home Assistant, even thou the zigbee2mqtt system in principle only supports one, but i hope they by time will see the need for a system which supports multiple "Coordinators", and officially support it! The situation where you need multiple coordinators, is when the distance between controlpoints is so big, that they cant see each other.
