I just installed tonight snapshot #1592 and had to this in order to get Z-Wave up and running again:
(in karaf)
openhab> feature:install openhab-transport-serial
openhab> list | grep -i zw
260 │ Active │ 80 │ 2.5.0.201905160433 │ openHAB Add-ons :: Bundles :: ZWave Binding
openhab> bundle:restart 260
Besides that, all looks fine. Even the Trådfri Gateway re-connected twice!
Hmm, something’s strange here …
System is sluggish. Z-Wave event are coming in, but rules cannot control lights.
Z-Wave lights took 3-4 minutes to respond.
Had to revert back to 2.5.0M1 - HowTo
After that I had to enable XMPP for my Harmony Hub.
HUE binding also failed to connect to my deconz on port 8090
Hopefully the snapshot is up and running again soon.
