maybe it works with older version because of a fallback to RC200_RC300 with an unknown system/info id?

I guess this is a way to deal with it? https://github.com/bosch-thermostat/bosch-thermostat-client-python/blob/dev/bosch_thermostat_client/db/db_IVT.json

    "195": {
      "value": "RC300",
      "name": "RC300/RC310/Buderus Logaplus",
      "type": "RC300_RC200"
    },

hi, there was no fallback function ever. Is it still working with 0.17.3? Because for me it seems something got disconnected in your installation. 195 is a boiler only, 164 is solar module, 224 is wall controller, 160 is a mixer. There is no km module. Anyway you don't have dhwCircuits and heatingCircuits, so how do you control your installation?

[comtel2000]

your right, 0.17.3 doesn't work anymore too. The local controller panel works perfect and all EMS systems are registered but the official Buderus app can't change anything related to dhwCircuits, heatingCircuits. All visualization are still there (Buderus app, iobroker). I'm afraid the KM100 needs a factory reset or it's killed by to many clients/requests.

[comtel2000]

ok, there is not reset function for KM100 but reset and change the private password via Buderus APP worked for me. Now the raw scan also contains ID=158 It was just confusing to still see all data but controlling was out-of-order. thanks for your time
