In the Anker App you see in the Device section a temperature information.

It would be helpful to have that temperature information also in the Solix Integration.
I.e. to understand why the battery is not charged (usually temperatures below 2 degrees)
or to set a warning notification for the hotter days.

Describe the solution you'd like

sensor.solix_site_sb_akkutemperatur

• just an idea

Describe alternatives you've considered

or similar

Additional context

I think it is missing right now as I don't find an entity with that information in the current Integration version

Hi,
The device temperature is not available via Cloud Api at this time, see Add temperature entity.
There is a new heating power field in the Api scene info response, but I have no idea how it is used for solarbanks.
You will have to monitor the Api response from time to time, especially when you see the heating on in the App.

You can use the Action to get Anker System information to fetch that data from Api.

@HakunaMatata47
Any success in getting System info via the service? Does it show values other than 0 in pei_heating_power field?
Here are the new solarbank fields that are unknown and needs interpretation and correlation to App values that might be shown...

    "other_input_power": "0",  => Unknown? Maybe DC input for battery charging when grid to battery is AC?
    "micro_inverter_power": "0",   => AC Output power for SB2? Should be lower than other output power values, if those are DC?
    "micro_inverter_power_limit": "0",   => Inverter output limit? Used for all SB2 models?
    "micro_inverter_low_power_limit": "0",  => Unknown
    "grid_to_battery_power": "0",   => DC or AC charging power?
    "pei_heating_power": "0"   => Total heating power for the batteries?

I see those values but especially pei_heating_power is 0 for me as I have a non-heated SB1 battery model. In the app you can see the temperature value but I don't see that in the system or device info when probing it with test_api.py Would be cool to get the battery temperature info if it can be identified in the API - maybe some day. as to the unknown fields: "total_charging_power": "32" "total_photovoltaic_power": "32" "micro_inverter_power": "32" Those have the same value while I look at it and it probably means it gets 32W from the solar panel and turns that into inverter power used i.e. to load the battery or put trough to the house From the naming of the unknown fields I come to the same conclusion as in your comments.

"micro_inverter_power": "32" => all micro_inverter_* field were introduced with the AC model as well as the pei_heating_power field, Probably the inverter fields are all non-sense for any other SB2 model, e.g. micro_inverter_power power is always the same at PV channel 3 power, which does not make sense at all.
I never saw pei_heating power other than 0....maybe it will come some day, maybe just for certain models and with certain firmware levels....
Total charging power response from Api is wrong. The library recalculates and reuses that total field to reflect battery power (positive and negative)
