To answer @joostlek 's question, I followed this part of the documentation. Each device has its own api endpoint so it seemed to make sense to implement it this way.

[joostlek]

How do you mean an API endpoint?

[crevetor]

Basically, each devices data is available at https://api_base/<device_unique_id>/data which seems to match this sentence in the documentation :

If you can map exactly one device endpoint to a single entity, you can fetch the data for this entity inside the update()/async_update() methods

[joostlek]

Yes, but that sentence doesn't explain that it should be 1 config entry. I think that would be beneficial. Otherwise with stuff like reauth, you'd have to enter your credentials for every device.

I can't go more in depth since I need answer on the config entry question
