I have restarted the Pi (a few times)..
And done a ZWave discovery .. this has got my motion detectors working again
But i have 4x ZWave TZ68E switch modules all of which have stopped working. I have tried removing the nodes for these switches, then doing a discovery and adding them again, which works fine and gives them a new ZWave node ID (as expected).
But they still dont work..
Something i've just noticed.. not sure if this helps..
If i click on the switch widget's On/Off buttons nothjng happens, but if i go into setup for that switch and set basic value to 0 or 255 the module switches on/off correctly, so im guessing theres something in the code for the switch widget thats not quite right?
Did you try restarting or doing a z-wave node discovery (from system->interfaces section)?
