Hello,
I’m new to Home Assistant. I’ve installed it on a RPI on my LAN. and also installed Mosquitto and Zigbee2MQTT addons. I have a SMLight SLZB-06M (firmware version is 2.7.1) but I do not manage to have Zigbee2MQTT connect to this one.
My configuration is this:
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: {}
serial:
port: tcp://192.168.1.17:6638
baudrate: 115200
adapter: ember
disable_led: false
advanced:
transmit_power: 20
On Zigbee2MQTT side, I get those logs:
[08:29:33] INFO: Preparing to start...
[08:29:33] INFO: Socat not enabled
[08:29:34] INFO: Starting Zigbee2MQTT...

at Controller.start (/app/lib/controller.ts:104:13)
at start (/app/index.js:149:5)
And on the SLZB side I get this
taskZB | Client limit has been reached!
I do not really understand as I do not have any other devices connected from what I know.
Any idea of the possible causes of this problem ?
Thank you for you help.
