- Issue of the topic: SMLIGHT SLZB-06M does not communicate with Mosquito
Dear All,
I’ve been strugling setting up my 1st zigbee device, even my zigbee adapter.
As you can see above i’m running the latest Openhab rlz, on an RPI4 with openhabian installed.
I’ve already sorted out to have the SMLIGHT SLZB-06M detected via and USB hub (as RPI4 fails to power devices properly.. my zwave adapter also is connected through that usb hub.)
What I’ve done and tried using forums, chatgpt and others..
I’ve installed Mosquito from openhabian-config, with default username and no pw.
I’ve instaled Zigbee2MQTT from openhabian-config.
Verified that the SMLIGHT SLZB-06M is connected and can be seen on USB0

Also have checked if the Mosquito is listening on port 1883.. opened 2 separate console-s. In 1 consolse i was connected to the port and on the other I’ve sent a hello command.. it did arrive.
openhabian@openhabian:~ $ sudo ss -lntp | grep 1883
LISTEN 0 100 0.0.0.0:1883 0.0.0.0:* users:((“mosquitto”,pid=707,fd=5))
LISTEN 0 100 [::]:1883 [::]:* users:((“mosquitto”,pid=707,fd=6))
I’ve set the zigbee2mqtt config as it was suggested by chatgpt to troubleshoot the issue..

If i start the zigbee2MQTT service and grab the logs i get this result:
