This is pre-release containing specific logs to diagnose the issue #600 (energy seems not restored or saved correctly).
Do not install if you don't have the #600 issue in your environment.
To activate the specific logs, you must add this line into the logger.yaml file:
default: warning
logs:
custom_components.versatile_thermostat.energy_debug: debug
After installing this beta release, you should update your logger.yaml file, restart and when you find the issue then send me the logs when the energy have changed (so around the time you change the configuration).
Full Changelog: 6.6.0...6.6.1.beta1
