Zigbee2mqtt has support for CC2652R chip used on this board. Download the Z-Stack coordinator firmware from @Koenkk's firmware repository. The firmware you'll need can be found under coordinator/Z-Stack_3.x.0/bin/CC2652R_coordinator_<date>.zip, as of writing the latest version available is CC2652R_coordinator_20210120.zip. Download and extract this and follow the "Flashing using BSL" instructions to burn this on your zzh.


Make sure that the CH340 USB-serial bridge drivers are installed and your device is recognised (instructions here).

With the correct serial port in use identified, edit your Zigbee2mqtt configuration.yaml:

  port: /dev/ttyUSB0  (change this if it is different on your machine)
  rtscts: false

The rtscts: false directive does not appear in the default configuration file but is crucial for the operation of zzh so please don't ignore that. Also note that it sits in the advanced: config group and not in serial:.
