Hi,
I had a bit of an issue this evening where something has gone horribly wrong with USB, I think the ports are fragged as I can’t get Z Wave up at all.
Zigbee shouldn’t have been affected but something’s gone wrong as that was working fine and now doesn’t and I can’t work out why even after reading many posts and all the documentation I could find.
I have Z2M connected to an SLZB-06 oven LAN, the adaptor is fine, no problems with that I can see and the config details it produces are:
# Pay attention, if you use the Z2M addon for HA, it is better to edit Z2M addon yaml configuration file directly (Select the 3 dot menu in the upper right corner → "Edit in YAML")
serial:
# Location of SLZB-06
port: tcp://192.168.2.234:6638
baudrate: 115200
adapter: zstack
# Disable green led?
disable_led: false
# Set output power to max 20
advanced:
transmit_power: 20
In Z2M I have this as the setup:
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

If it helps the full error I get is the Z2M log is:
Can anyone tell me if there are any errors here I’m missing please?
