Octopus free (power up) event support

What's Changed

Octopus free (power up) event support

Predbat can automatically detect Octopus free events and adjust your battery plan according.

For Predbat to automatically manage Octopus free sessions the following additional configuration item in apps.yaml is used.

Note: You must have signed up to Octoplus to benefit from these events

Like the electricity rates this is set in the apps.yaml template to a regular expression that should auto-discover the Octopus Energy integration.

octopus_free_session - Will point to the free event sensor that is exposed by the Octopus Energy Integration. This event sensor contains the dates/times of
all the free events.

  octopus_free_session: 're:(event.octopus_energy_([0-9a-z_]+|)_octoplus_free_electricity_session_events)'

Note: This event may need to be enabled in Home Assistant first How to Enable Octopus events

If you normally increase your house usage during a free session then you can change input_number.predbat_load_scaling_free to allow Predbat to assume an energy
increase in this period. E.g. setting to a value of 1.2 would indicate you will use 20% more energy that normal during this period. (Default is 1.2)

If you do not want Predbat to see these sessions then comment out the octopus_free_session setting.
