Exploring the Potential of the ADC-T 2000 Z-Wave Thermostat

I’ve been diving into the world of smart thermostats, and the ADC-T 2000 Z-Wave Thermostat by Alarm.com has caught my attention. However, I’ve hit a snag with its configuration parameters that I’m hoping the community can help me untangle.

After setting up the thermostat, I noticed that the configuration parameters weren’t responding as expected. The device reported values that seemed out of range, and attempts to adjust them according to the binding’s suggestions were ignored. To troubleshoot, I tried an experiment: I copied a value from the ‘minimum cool setpoint’ and pasted it into the ‘maximum heat setpoint’. Surprisingly, it worked! The thermostat accepted the value and set the ‘max heat setpoint’ to 50 degrees, which matched the ‘minimum cool setpoint’ value. This suggests that there’s a conversion happening between the expected values and the 9-digit format the device uses internally.

While this experiment was a small victory, it’s clear that there’s more to uncover. I’m curious if anyone has figured out how to decode or encode these values to fully utilize the thermostat’s capabilities. The device’s potential is evident, and resolving this issue would unlock its full functionality for temperature control and energy management.

If anyone has insights or experiences with similar devices, I’d love to hear your thoughts! Let’s explore this together and see if we can crack the code on these configuration parameters.
