Switch hc1 / hcx to off from frontent or get real state on frontend

[honikos]

Is your feature request related to a problem? Please describe. I use Bosch custom component v0.18.3 HTTP -> IVT Logamatic HMC300, Gateway iCom_Low_NSC_v1, firmware 04.08.02.

Describe the solution you'd like The debug scan tells me I can't switch off hc1, despite it's now off. This was achieved with the remote-controll rc100 (Bosch). If I set RoomSetpoint lower than 5, the screen on rc100 allows me to switch off the hc1. On lovelace I can't set temperature lower than 5.5 degree (also said in debug_scan).

{
      "id": "/heatingCircuits/hc1/currentRoomSetpoint",
      "type": "floatValue",
      "writeable": 0,
      "recordable": 0,
      "value": 0.0,
      "unitOfMeasure": "C",
      "state": [
        {
          "off": 0.0
        }
      ]
    }

With ems-esp it seems to be possible to switch off hc. https://github.com/emsesp/EMS-ESP32/blob/main/src/devices/thermostat.h (example rc100h) Sometimes I have an update on Lovelace that the hc1 is off, but usually the frontend hc1 is on (heating) even it was turned off with rc100.

Describe alternatives you've considered Is it possible to

1. get the real state of hc1 to the frontend or
2. even switch the rc100 or heatpump.hc from frontend?

Now real state is displayed in frontend. I couldn't figure it out how to implement state off.
