HA is workin in the new machine. Made sure the IP is the same. Everything seems to have loaded all good, except z2m.
The coordinator (SLZB-06) is reachable, in LAN mode, and using the same IP. Plugged in a different USB socket ofc, but that's just for power.
My add on config:
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
Don't remember any of this. It's been 2 years since I set this up.
