Fronius Wattpilot Home 22J Partial Support

[EinSchwerd]

The Fronius Wattpilot Home 22J inverter can be connected using firmware 42.5 (it uses OCPP 1.6J).
The integration recognises 52 entities; however, some are never set (always remain in an Unknown state). Parsing of some entities could also be improved, as they show up as a composite string (e.g. the features sensor is a list of '|' separated strings).

Below are the screenshots of the exchanged entities and values:

Let me know if I can provide any additional information to improve the integration for this inverter and to get it added to the official documentation.

Additionally, when I reboot Home Assistant, I receive a 'Charger Rebooted' notification:

This is not accurate as the charger did not reboot. The connection may have been re-established, but the device itself was running uninterrupted the whole time.

In terms of functionality, what would you like to see in the integration to better support Wattpilot?

[EinSchwerd]

1. The Charger rebooted notification has no added value on reboot. This should only be displayed when the charger actually reboots.
2. The sensors with 'enumeration' could have human-readable states displayed (compared to the raw values the charger sends at the moment)
3. The sensors that are always in an 'Unknown' state should be disabled in HA by default
4. The 'Vendor', 'Model', 'Serial' (and maybe even the 'Firmware Version') don't need to be sensors as they are displayed as part of the device info
5. The 'Number of connectors' is always 1 and will never change; this can also become part of the device info

6. The documentation could give a brief overview of some of the sensors and a 'how to start/stop charging' section.
7. Some sensor naming is ambiguous, e.g., 'Reconnects' should mean issues with the wifi or with the charger-to-car interface;
8. The charger does not currently support bi-directional charging; the 'Import' and 'Export' sensors might need either better naming, more context, or one of them being disabled. e.g. is it imported from the grid or from the car, or to the car?
9. Weekly, monthly and yearly charging meters can also be useful to many users

Thank you for considering some of these features.
