Intergas gateway

This integration links Home Assistant with your Intergas Lan2RF gateway, including the boiler and any room thermostats attached to it. The integration uses the incomfort-client library.

Supported devices

The Intergas Lan2RF Gateway connects thermostats based on the OpenTherm standard. An example of such a thermostat is the Comfort Touch Thermostat. The thermostats and LAN2RF gateway are often sold as a set. The gateway is suitable for use with Intergas Kombi Kompakt HRE and HReco appliances from year of manufacture 2014. If the Comfort Touch thermostat is used together with the gateway, then this will work in combination with Intergas Kombi Kompakt HRE, HReco, or Xtreme devices from year of manufacture 2017.

Boiler

The boiler is represented as a Water heater device. It will report the boiler’s state and current_temperature. The gateway does not expose any means to directly control the boiler or change its configuration.

Note that the current_temperature will switch between the CV (circulating volume) 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.

Rooms

Any room thermostats (there can be 0, 1 or 2) are represented as Climate devices. They will report the thermostat’s target temperature and current_temperature and the target temperature can be changed. This is similar to changing the target temperature override using the Comfort Touch App that comes with the thermostat/gateway. Note that any override will be reset when a new set point is reached on the thermostat’s schedule.

Configuration

To add the Intergas gateway integration to your Home Assistant instance, use this My button:

Intergas gateway can be auto-discovered by Home Assistant. If an instance was found, it will be shown as Discovered. You can then set it up right away.

The hub does not have to be in the same network as HA, but must be reachable via port 80/HTTP.

The above configuration can also be adjusted later via Settings > Devices & services, select “Intergas InComfort/Intouch Lan2RF gateway” and click and select Reconfigure.

Options

Options for Intergas gateway can be set via the user interface, by taking the following steps:

• Browse to your Home Assistant instance.
• Go to Settings > Devices & Services.
• If multiple instances of Intergas gateway are configured, choose the instance you want to configure.
• Select the integration, then select Configure.

Sensors for diagnostics

Note that all sensors are disabled by default.

• Sensors
  • Boiler Pressure: Indicates the boilers pressure.
  • Boiler Temperature: Indicates the central heating temperature.
  • Boiler Tap temperature: Indicates the tap water temperature.
• Binary sensors
  • Boiler Burner: Indicates if the burner is on.
  • Boiler Fault: Indicates if there is a problem. The fault code is set as an attribute.
  • Boiler Hot water tap: Indicates if the hot water tap is running.
  • Boiler Pump: Indicate the pump is running for cental heating.

Troubleshooting

In case setting up an older gateway type fails, then try to leave username and password fields empty.

Data updates

The Intergas Lan2RF Gateway will fetch state data from the gateway every 30 seconds. When the target temperature on the thermostat is changed, it might take some time for the set point to be updated on the Home Assistant climate entityAn entity represents a sensor, actor, or function in Home Assistant. Entities are used to monitor physical properties or to control other entities. An entity is usually part of a device or a service. [Learn more].

Remove integration

This integration follows standard integration removal, no extra steps are required.

To remove an integration instance from Home Assistant

1. Go to Settings > Devices & services and select the integration card.
2. From the list of devices, select the integration instance you want to remove.
3. Next to the entry, select the three-dot menu. Then, select Delete.

Automation

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

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

Other properties are available via each device’s attributes.
