 This custom component for Home Assistant is an upgrade and is a complete rewrite of the component "Awesome thermostat" (see [Github](https://github.com/dadge/awesome_thermostat)) with addition of features.

+> * **Release 3.3**: add the Air Conditionned mode (AC). This feature allow to use the eventual AC mode of your underlying climate entity. You have to check the "Use AC mode" checkbox in configuration and give preset temperature value for AC mode and AC mode when absent if absence is configured
+> * **Release 3.2**: add the ability to control multiple switches from the same thermostat. In this mode, the switches are triggered with a delay to minimize the power required at one time (we minimize the recovery periods). See [Configuration](#select-the-driven-entity)
 > * **Release 3.1**: added detection of open windows/doors by temperature drop. This new function makes it possible to automatically stop a radiator when the temperature drops suddenly. See [Auto mode](#auto-mode)
 > * **Major release 3.0**: addition of thermostat equipment and associated sensors (binary and non-binary). Much closer to the Home Assistant philosophy, you now have direct access to the energy consumed by the radiator controlled by the thermostat and many other sensors that will be useful in your automations and dashboard.
 > * **release 2.3**: addition of the power and energy measurement of the radiator controlled by the thermostat.
 > * **release 2.2**: addition of a safety function allowing a radiator not to be left heating forever in the event of a thermometer failure
 > * **major release 2.0**: addition of the "over climate" thermostat allowing you to transform any thermostat into a Versatile Thermostat and add all the functions of the latter.
