Tibber - Pulse Battery Sensor

It would be great to have a sensor reading the Tibber Pulse Battery Level. With this, notifications could be sent if battery has to be changed.

I do not think the data are available from the Tibber API.

The Tibber app notifies me in case the battery level is low. There must be some kind of API, otherwise the app wouldn’t know that the battery level is low.

The app is not using the public API

Hmm, ok, the battery’s voltage seems to be part of the node’s metrics. But that’s something which cannot be accessed remotely?

Didn’t even know it had batteries!
How often do they need replacement though? I’ve had mine for years…

But could any of you who has experience with Tibber Pulse look at this:

My DB is 50MB after deleting Tibber integration and creating a new database, it was almost 800MB before. How do you handle this? It is writing the SD or eMMC to death.
