Further investigation suggests that there is something awry with the channel config parameter in zwave items db for the LSControl Temperature Sensor. Similar to this issue
You can see the point of failure when comparing the DEBUG output for the (working) Battery channel to the Temperature channel:

Note in particular:
17:08:44.998 [DEBUG] [verter.ZWaveMultiLevelSensorConverter] - NODE 135: No sensorType set for channel zwave:device:z-stick:node135:sensor_temperature
So presumably there is no way to manually resolve this and it needs to be updated in the database?
