19.0.0 (2026-08-03)

Add Intelligent State of Charge to show vehicle battery charge level (Thanks @matt7aylor) (ffd980f)
Added new sensors to represent power up and power down events which will supercede saving session and free electricity session sensors - Full reasoning can be found at https://bottlecapdave.github.io/HomeAssistant-OctopusEnergy/architecture_decision_records/0004_rename_saving_sessions_free_electricity_sessions (2 hours dev time) (ae7ce2f)
Added optional enforcement of intelligent 6 hour cap (3 hours dev time) (24c796c)
Added sensor for capturing dispatch hours during current charge cap (1 hour dev time) (9bb5631)
Removed free electricity binary sensor in favour of calendar sensor (30 minutes dev time) (afa4d38)
Removed saving session binary sensor in favour of calendar sensor (30 minutes dev time) (9def3d8)
Removed greener nights sensors due to service being discontinued (30 minutes dev time) (09a10cd)
Updated deprecated isOctoplusEnrolled field to use new enrollmentStatus field (15 minutes dev time) (4ac32b2)
Updated intelligent charge target to support values from 0 to 100 (5 minutes dev time) (b6cfe42)
Updated intelligent target time to allow setting 30 minute intervals throughout entire 24 hour block (5 minutes dev time) (9c552da)
Updated rate and standing charge sensors to be reported as measurement to support min/max/average statistics. This is to align with other HA integrations for this type of sensor (30 minutes dev time) (8ced498)

Greener night sensors are no longer provided due to the service being discontinued. Please update
all dashboards and automations accordingly
With the type of sensor changing for rate and standing charge sensors, you may need to reset the
statistics associated with these sensors. This may result in you losing long term history for these
sensors.
