Fronius: Storage Battery icon not showing status of charging

[thecem]

The problem

The Battery on Fronius integration don't show the charging state. If there is device_class set to battery for the SOC the battery icon shows the SOC in relation, but if it is charging it does not show the charging state.

Is there a possibility to change the integration, that the charging state is an attribute of the SOC? Or a possibility to set the parameter that HA could show the battery icon accordingly, like it is in other integrations, when the battery is charged.

What is version of Home Assistant Core has the issue?

core-2021.6.5

What was the last working version of Home Assistant Core?

Hey there @nielstron, mind taking a look at this issue as its been labeled with an integration (fronius) you are listed as a codeowner for? Thanks! _{^{(message by CodeOwnersMention)}}

Hi @thecem, thanks for the suggestion. Can you point out the exact sensors that should take into account the charging state of the battery in their icons? My own device does not feature a battery, so I have no resources to test it myself.

[thecem]

Thanks for your answer! The one for charging state could be sensor.power_battery_fronius_power_flow_0_url values are -10000 up to 10000, actual the battery is charged with value: -366.3 charging state of battery is: sensor.state_of_charge_fronius_power_flow_0_url

So it would be nice if a negativ value of the power_battery sensor could be used for the charging state of the battery icon of the state_of_charge sensor. Additional the device_class of state_of_charge sensor should be by default battery.

if you need more details, logs, tests let me know.

I think I will not get to implement this myself, but this thread may be interesting for anyone with some coding experience and a fronius device with batteries :)

At least when flow for HEMS will come in 2021.8.. but if you would like to have this in place, there is an option with Sunspec integration https://github.com/CJNE/ha-sunspec to have the right battery sign.
