Move to experimental mode

Support for Goodwe solar inverters is present as native integration of Home Assistant since its release 2022.2.

The standard HA integration is recommended for most users.

This custom component is now experimental version with features not (yet) present in standard HA's integration and is intended for users with specific needs and early adopters of new features. Use at own risk.

Migration from HACS to HA

If you have been using this custom component and want to migrate to standard HA integration, the migration is straightforward. Just remove the integration from HACS (press Ignore and force uninstall despite the warning the integration is still configured). Atrer restart of Home Assistant, the standard Goodwe integration will start and all your existing settings, entity names, history and statistics should be preserved.

(If you uninstall the integration first, then uninstall HACS component and install integration back again, it will also work, but you will probably loose some history and settings since HA integration uses slightly different default entity names.)

Apply Eco mode power changes immediately

When inverter is in of the new Eco charge mode or Eco discharge mode any change of value of the Eco mode power will be immediately applied on inverter. (Prior to v0.9.8.1, it was applied only upon operation mode change).
Fix Eco mode power number entity when multiple inverters are present.

Created new Eco Charge and Eco Discharge work modes

Created new (emulated) work modes Eco charge mode and Eco discharge mode as convenience shortcuts to enter inverter Eco Mode with single configured charging (or discharging) group valid all the time (from 00:00-23:69, Mon-Sun) and with charging power set to the value of another new configuration entity called Eco mode power.
