The incomfort integration links Home Assistant with your Intergas Lan2RF gateway for integrating the boiler and any room thermostats attached to it.

The boiler is represented as a Water Heater device. It will report the boiler's state and temperature (current temperature). The gateway does not expose any means to directly control the boiler or change its configuration.

Note that the temperature will switch between the CV and Tap temperatures according to the current operating mode of the boiler. If the boiler is neither pumping nor tapping, it will be reported as the higher of the two.

Any room thermostats (there can be 0, 1 or 2) are represented as Climate devices. They will report the thermostat's target_temperature (setpoint) and current_temperature and the setpoint can be changed.

In addition, there is a Sensor for CV pressure, CV temperature, and Tap temperature, and a Binary Sensor that will be on if there is a fault with the boiler (the fault code will be a state attribute).

To send an alert if the CV pressure is too low or too high, consider the following automation:

{% raw %}

- alias: Low CV Pressure Alert
  trigger:
    platform: numeric_state
    entity_id: sensor.cv_pressure
    below: 1.0
  action:
  - service: notify.pushbullet_notifier
    data_template:
      title: "Warning: Low CH Pressure"
      message: >-
        {{ trigger.to_state.attributes.friendly_name }}
        is low, {{ trigger.to_state.state }} bar.

{% endraw %}

Other properties are available via each device's attributes.

{% linkable_title Configuration %}

To add your Lan2RF gateway into your Home Assistant installation, add one of the following to your configuration.yaml file.

Older gateways do not require user authentication:

# Example configuration.yaml entry, older firmware with no user credentials
incomfort:
  host: IP_ADDRESS

Alternatively, if a username & password is printed on the back of the gateway:

# Example configuration.yaml entry, newer firmware with user credentials
incomfort:
  host: IP_ADDRESS
  username: USERNAME
  password: PASSWORD

The hub does not have to be in the same network as HA.

{% configuration %} host: description: The hostname/IP address of the Lan2RF gateway. required: true type: string username: description: The username of the Lan2RF gateway, if any. required: inclusive type: string password: description: The password of the Lan2RF gateway, if any. required: inclusive type: string {% endconfiguration %}
