Zwave haven't a "Adapter" yet. This means no local calibration Support.

Feel free to make an PR. Or provide information about how the offset can be set with zwave

What is local calibration exactly? I have a bunch of Zwave TRVs (Aeotec clones of the Eurotronics Spirit Z), and am expecting another set of clones from another brand soon as both Eurotronics and Aeotec models have been discontinued. They all share a hidden Manufacturer Specific mode (appearing as Heat/Cool in HA) where the valve opening can be set manually via a number entity in HA (between 0 and 100, 0 being fully closed, and 100 fully open), would that qualify as local calibration?

Do note that in this case the thermostat mode should not be modified by better thermostat, or it should provide a way to go back to the hidden mode, which is not possible via normal means, only via a service call like so:

service: zwave_js.set_value
data:
  command_class: "64"
  property: mode
  value: 31
target:
  device_id:

I have some Eurotronic z-wave TRVs and I guess it's not the manufacturer specific mode where you can set the valve manually, I would guess the functionality that better-thermostat is using is configuring the offset of the detected temperature towards the current temperature (for one of my valves it would be number.thermostatic_valve_temperature_offset_3).

Am I right that better-thermostat works in the following way?

• External thermostat measures 20°C
• Internal thermostat measures 16°C
• better-thermostat sets offset to +4°C so that the TRV adapts its internal temperature towards 20°C

Thus it is required to develop an adapter that gives better-thermostat "the knowledge" of how to set this kind of offset?
