v2021.12.1

Bug fixes:

• Fix heater remaining on while thermostat is switched off (#34).
  When thermostat was switched off while heating since less than the minimum cycle duration, the heater switch could remain in on state until the thermostat is switched on again. In this release, switching off the thermostat will force the heater switch to off whatever the duration of the last on cycle.

v2021.11.9

Breaking change !!

Be careful to the new setting unique_id that might create a duplicated entity. See below for workarounds.

What's new:

• Add optional unique_id parameter: Breaking change !
  Closes #22.
  It allows to customize the entity through UI. Please note that leaving this setting empty may duplicate the previously existing entity, and the old one will then be marked as unavailable.
  Example:
  • Old entity becoming unavailable : climate.room_thermostat
  • New entity : climate.room_thermostat_2
    You should note the ID of the old entity, then delete the old entity in the UI and rename the new entity using the same ID as old entity to restore functionality of all your automations, scripts, cards, etc...

To avoid this, update Smart Thermostat using HACS, then stop Home Assistant, set the unique_id parameter in YAML with the ID of the old smart thermostat entity as shown in Developers tools > States (example if old entity ID is climate.room_thermostat in developers tools, then write unique_id: room_thermostat in the YAML file), save file and then start Home Assistant.

• Add service to set PID gains :
  Use the smart_thermostat.set_pid_gain service to adjust the PID gains without requiring a restart of Home Assistant. Values are saved to Home Assistant database and restored after a restart. Please consider saving the final gain parameters in YAML configuration file when satisfied to keep it safe in case of database corruption.

• Add service to set preset modes temperatures:
  Use the smart_thermostat.set_preset_temp service to set the temperatures for the preset modes. Closes #17.

• Add service to clear the integral part:
  Use the smart_thermostat.clear_integral service to reset the integral part of the PID controller to 0. Useful when tuning the PID gains to quickly test the behavior without waiting the integral to stabilize by itself.

• Add integration reload service:
  Use the smart_thermostat.reload service to reload the thermostat from scratch without requiring a restart of Home Assistant.

Bug fixes:

• Fix integral windup when set point is changed while heating is on and modulating.
• Fix logging issue when autotune is successful.
• Fix error when calling service climate.set_preset_mode to set preset to 'none' while no preset is active (#28)
