Which version of bsblan is on the board connected to your heating system?

Hello @liudger, I am also concerned by this issue. I am using version 3.2.2-20230606224119 with for now a rudimentary set of parameters. Which version of BSB-LAN do you support ?
from python-bsblan.

I had the same issue but could fix it by reading the /Q function ("Reglerspezifische Parameterliste") docs and then using the BSB_LAN_custom_defs.h from 2.2.1.
(I've also done the rest of the recommended actions there). Now the home assistant device configured correctly and I have a thermostat device :-D

PS: with the "proper" custom_defs.h from the bsb lan folks, the error re-appeared

Could it be that the library gets confused because the API_V3 constants use 700.0, but the API doesn't return such values?

Since I don't always have access to this device, here's also a dump of all available parameters from it.
