I’m running my HA inside a VM running on a Synology NAS which is located in my basement. I want to integrate various ZigBee devices in HA without using the device’s official gateways (namely, the Xiaomi Gateway for Mija/Aqara devices).
I plan to use the HA Zigbee2MQTT add-on for this and got myself Slaesh’s CC2652RB USB stick. However, from what I’ve seen so far, every guide on how to set up Zigbee2MQTT with HA relies on the ZigBee coordinator stick being plugged directly into the HA server. Unfortunately, with my setup, the signal would then never reach my ZigBee devices located in the upper floor. There’s also no ZigBee devices/bridges in-between the basement & upper floor.
Is it possible to use the ZigBee coordinator stick with e.g. a Raspberry Pi and to then somehow integrate that ZigBee Pi with my HA server? Or is my only option to run some ZigBee bridge(s) in-between?
Thanks in advance for every help!
