Just a note for those trying to update their zwave binding from Stable to Snapshot, here is what worked for me.
Openhab2 installed using apt-get running on Ubuntu desktop 1604.
Uninstall the stable binding from the Paper UI -> Add-ons -> Bindings.
Download the latest .jar snapshot from the following location:
Copy the .jar file to the addons directory:
sudo cp /path/to/download/org.openhab.binding.zwave-2.1.0-SNAPSHOT.jar /usr/share/openhab2/addons
Install the serial feature as discussed in post 2
sudo systemctl restart openhab2
To check which version of the zwave binding is running, SSH to the Karaf console (from the host running Openhab).
ssh -p 8101 openhab@localhost
(passwd is habopen)
At the openhab prompt type: bundle:list | grep ZWave
openhab> bundle:list | grep ZWave 209 | Active | 80 | 22.214.171.124706022154 | ZWave Binding
I hope this helps others, thanks to Chris for maintaining the Zwave binding!!
