kwb integration integrates the sensors of KWB Easyfire pellet central heating units with the Comfort3 controller (https://www.kwb.net/produkte/) into Home Assistant.
Direct connection via serial (RS485) or via telnet terminal server is supported. The serial cable has to be attached to the control unit port 25 (which is normally used for detached control terminals).
Since this serial protocol is proprietary and closed, only most temperature sensors and a few control relays are supported, the rest is still WIP (see https://www.mikrocontroller.net/topic/274137).
Direct connection via serial port:
# Example configuration.yaml entry - platform: kwb name: kwb device: "/dev/ttyUSB0" type: serial raw: false
Telnet terminal server with a serial-ethernet converter:
# Example configuration.yaml entry - platform: kwb name: kwb host: <ip> port: 23 type: tcp raw: false
Take a good look at which configuration variables are for
TCP use or for
Should the raw serial output be shown as a sensor.
The name of the device used in the frontend.
(For serial use) The serial device of the machine.
(For tcp use) The IP-address of the serial server.
(For tcp use) The TCP-port of the serial server.
Type of sensor, you can choose between:
