WARNING: 2021.9 breaks Energy dashboard derived from this component about sensor.fronius HOT 4 CLOSED

To fix this mess we can do something like this, or just update it and let users on 2021.8 skip the update or fix the mess themselves :P

1. Update this integration as you have prepared so that it supports HA 2021.9.x
2. Document in the README how you can use the customize feature in HA to modify attributes for the required sensors so that it can still be used in 2021.8.x for users that does not upgrade immediately, but decides to use the latest version of this integration.

For some reason I could not get the UI config for customizing entities to work, at least not in 2021.9.0. The only available option for state_class was measurement...but doing it the old fashioned yaml-way worked.

Here is what needs to be added to make an updated version compatible with 2021.8.x

configuration.yaml

homeassistant:
  customize: !include customize.yaml

customize.yaml

sensor.fronius_total_energy:
  state_class: measurement
  last_reset: "homeassistant.util.dt.utc_from_timestamp(0)"
sensor.fronius_smartmeter_energy_ac_consumed:
  state_class: measurement
  last_reset: "homeassistant.util.dt.utc_from_timestamp(0)"
sensor.fronius_smartmeter_energy_ac_sold:
  state_class: measurement
  last_reset: "homeassistant.util.dt.utc_from_timestamp(0)"

Where "fronius" in the sensor name needs to match the name of the integration. And a note that this needs to be deleted when the user upgrades to 2021.9.x

@nilrog appreciate your thoughts on this one (and also the breaking changes noted in the readme). Concerned that HA 2021.9 broke the component (despite suggestions there would be some months of compatibility) and so how best to convey this as visibly as possible.

This is a bug in HA that they are not following their own documentation. It will be impossible for third-party integrations to solve this since not everyone will update to 2021.9.0 immediately. And if we were to release a new version through HACS for 2021.9.0 then people, that may still be on 2021.8.x, will update and we will be broken for them.
