Hi, are you planning or do you have somewhere a working version that would allow you to read data from Foxess, but bypassing HA. So that it could be fired straight from the python interpreter?

No, no plans and there likely won't be any I'm afraid.

We're very tightly integrated with HA: we read register values over modbus and turn them into human units, then send that to HA which handles all of the formatting and display; all of the setup and configuration is handled by HA; the integration sensors (total PV1, etc) are implemented in HA; the storage we use for the charge period sensors is handled by HA; etc etc. See e.g. here.

You might be able to create a tool which uses the entity definitions to parse the registers it reads, but that will depend on HA.

You can read registers directly from the command-line using e.g. modpoll or pymodbus, but then you'll need to do your own parsing.

It's a pity , I'm just trying to decode it to a simpler form. Unfortunately, not knowing the HA operating scheme is quite problematic at this point. Anyway, I'm mega grateful for running this project, at least I know it's possible.
