Hi, I’m seemingly unable to make zigbee2mqtt work with the ZBT-1 adapter so hopefully one of you will be able to help or point me in the right direction - thanks.
This is my current YAML configuration per this guide:
data_path: /config/zigbee2mqtt
socat:
enabled: false
master: pty,raw,echo=0,link=/tmp/ttyZ2M,mode=777
slave: tcp-listen:8485,keepalive,nodelay,reuseaddr,keepidle=1,keepintvl=1,keepcnt=5
options: "-d -d"
log: false
mqtt:
server: mqtt://core-mosquitto:1883
user: mqtt-user
password: pi
serial:
adapter: ezsp
port: >-
/dev/serial/by-id/usb-Nabu_Casa_Home_Assistant_Connect_ZBT-1_3e903585ac38ef119b10337af3d9b1e5-if00-port0
baudrate: 115200
rtscts: true
And this is the error I keep getting in the log:
