PredHeat Integration, bug fixes & Tidy up

What's Changed

• PredHeat is now integrated into Predbat.
• New automation API feature.
• Lots of small bug fixes

WARN Breaking change - if you use AppDaemon then ha_url/ha_key must now be set in apps.yaml, Predbat will no longer use AppDaemon to communicate with Home Assistant

New features

Integration Predheat into Predbat

The PredHeat tool for predicting energy consumption of heating systems is now integrated into Predbat. Please see the chapter of the documentation for details.

• Predheat integration by @springfall2008 in #1523
• Create example_chart_predheat.yml by @springfall2008 in #1524
• Fix for clash between predheat options and config options by @springfall2008 in #1530

Use of Ohme with tariff's other than Octopus Intelligent GO

Predbat can now take the schedule from Ohme as if it is using Octopus Intelligent GO but if octopus_slot_low_rate is set to false in apps.yaml it will not modify the energy rates (Intelligent GO always charges at low rate).

• Allow use of octopus slot for other tariffs by @springfall2008 in #1512

Support for power based sensors

If an energy sensor is set to a power sensor (units in Watts) then it will be integrated to create Energy (in kWh). This is not always a very accurate method but is better than reading Watts as energy.

• Integrate W to Wh by @springfall2008 in #1510

Added new experimental automation API for Predbat

See the Manual API chapter for the documentation for details.

WARN This is an expert mode feature and incorrect use may cause Predbat to crash or do strange things.
