 ⚠️ `Not Ready - Force Stopped` was added to overcome a gotcha with Hypervolt. If the user manually stops a charge by switching charging off via the app or integration, the Hypervolt charger remembers this state and if later is switched into Schedule Charge activation mode, the scheduled charge _will not automatically start_ as might be expected. To overcome this, the Charging switch needs to be manually toggled. This can be done when in Scheduled mode even outside of the schedule window and will switch the `Hypervolt Charging Readiness` state back to `Ready`. ⚠️ In the Hypervolt app, there doesn't appear to be a way of telling whether the charger is ready or not.
