v0.9.0

What's Changed

Dynamic Schedule v2

The Energy Price and Power Schedule sensors now use the Dynamic Schedule V2 API, available in Sessy firmware 1.9.2 and up.
This changes the attributes of the sensor.sessy_dxxx_power_schedule and sensor.sessy_dxxx_energy_prices entities slightly to be compatible with 15-minute pricing windows.
If the new version is not yet available on your Sessy, the sensor will maintain it's original behavior.
(Move to Dynamic Schedule v2 API by @PimDoos in #138)

Temperature based limit

The temperature-based limit setting can now be turned on or off from within Home Assistant.
(Add temperature limit config switch by @PimDoos in #139)

Removed old update entities

The deprecated update entities to update the Dongle and Battery pack separately have been removed. The combined update entity which updates both at the same time has been the default for a long time now, and these old entities were disabled by default since Sessy firmware 1.6.8.
(Remove seperate update entities (replaced by OtaTargetAll entity) by @PimDoos in #140)
