Jasco Smart Switch 4103 not initializing

It is already in the database so chances are high that your zwave binding version is too old:

Upgrade to the latest zwave snapshot or even better development version and you should be good to go.
Btw, it is not necessary to link any channels to the controller, unless your are doing some special stuff with it :grinning:
