Home Assistant custom component for the web2com interface from ochsner. Use the python module ochnser-web2com

This component is in an experimental stage.

Installation

Create a folder "web2com" in "custom_components". Copy all files to this folder.

custom_components/web2com/__init__.py
custom_components/web2com/manifest.json
custom_components/web2com/sensor.py
custom_components/web2com/service.yaml

Copy "ochsner_web2com.yaml" to your configuration folder. Copy "ochsner_web2com_template.yaml" to your configuration folder.

Add a link in you configuration.yaml file

web2com: !include ochsner_web2com.yaml
template: !include ochsner_web2com_template.yaml

Set the user name and the ip number of the web2com server in the file ochsner_web2com.yaml

ip_address: 192.168.188.50
username: OEM

Optional: In the file ochsner_web2com.yaml the authentication method can be set. If the value is not set then Digest authentication will be used.

authentication: Digest

or

authentication: Basic

Set a password in the secrets.yaml file

web2com_password: your_password

With the climate_template it is possible to combine a sensor and a service to a climate integration.

climate:
  - platform: climate_template
    name: RaumtemperaturSollwert
    modes:
      - "auto"
    min_temp: 15
    max_temp: 30
    temp_step: 0.5
    current_temperature_template: "{{states('sensor.Normal_Raumtemperatur_Heizbetrieb') }}"
    set_temperature:
      - service: web2com.heating
        data:
          temperature:  "{{ temperature }}"

Configuration

A sensor can be set via the ochsner_web2com.yaml file.

sensors:
  - name: Heizenergie Teil 1 MWh
    scan_interval: 30
    unique_id: web2com_HeizenergieTeil1MWh
    id: /1/2/1/125/10
    unit_of_measurement: MWh
    device_class: "energy"

One service is set up: NormalSetpointRoomTemperature
