C-Stat 11-ZW slow to react

I have a Horstmann C-Stat 11-ZW I can send new temperature setpoints to it but sometimes takes a good few minutes as when I send the change it sits waiting for device to wake up, my logs also get a Device Not Responding error.

Is there anywhere I can set the thermostat to wake up or poll/listen more often? Cant see any settings ion the zwave section on the thermostat itself.

I’m having a similar issue with my Honeywell stat. I get “Device not responding” and “Device responding again” log entries all the time, but I’m not actually having problems with the thermostat. Control works, scheduled setpoint scenes work properly. It’ sliek a check engine light when nothing is actually wrong.
