detect battery care aka Batteriepflege

[doncuco]

Hello,
is there any way to detect that the battery is doing battery care or batteriepflege.
sometimes I am wondering why my battery is not discharging despite it is fully loaded.
best regards

Sonnen batteries have a REST API that you can access. This will give you control over the battery and allow queries of many parameters. If you log into the battery select the software menu it's fully documented there.

Well I am sure that @doncuco knows that - after all, this is a github Repo that already makes use of the REST api.
But how exactly can we know that the battery is in "care modus" ? I also have this "issue" one time every year and believe me, it makes me frown every time :-)

I have to log in to the local web interface of my Sonnen battery, and there I can somewhere find a note that the battery is currently undergoing some maintenance. I thin this always takes more than one day! It would be great to be able to query this with the REST api, but if I remember correctly the "operation mode" does not reflect it.

Yes, I think in the OpenAPI specification there is mention of dischargeNotAllowed: 1. *Check dischargeNotAllowed from /api/v2/status* - This boolean indicates whether discharging is restricted due to maintenance.

This is a Node-Red flow that would extract 'dischargeNotAllowed' and update a binary sensor in Home Assistant with it's value:

dischargeNotAllowed.json

Thank you for that. I will Test it. But i am Not quite Site of this works for me.
I have a nodered Flow Running, that Charges my battery based on the prices regarding the battery loss.
He also calculates the battery percentage price and blocks from discharging if rubber is cheaper.
I am aware of the api. But i was hoping that there is a way in home Assistant, that could be integrated in this repository.
