Genius Hub

The geniushub integration links Home Assistant with your Genius Hub (the hub does not have to be in the same network as HA).

Currently only Radiator and Hot Water Temperature zones are supported. Within HA, each Radiator zone will appear as a Climate device, and each Hot Water Temperature zone will appear as a WaterHeater device.

The device’s operating_mode can be set to one of off, timer, on (i.e. Override mode) or eco. The eco mode is a proxy for the Footprint mode and so is only available to Radiator zones that have room sensors.

Other properties are available via the device’s state attributes, which includes a JSON data structure called status. For example, in the case of Radiator zones/Climate devices:

  "status": {
    "type": "radiator",
    "temperature": 19,
    "occupied": False,
    "override": {
      "duration": 0,
      "setpoint": 16

This data can be accessed in automations, etc. via a value template. For example:

value_template: "{{ state_attr('water_heater.boiler_h_w', 'status').override.setpoint }}"

In the specific case of Radiator zones with room sensors:

value_template: "{{ state_attr('climate.main_room', 'status').occupied }}"

Currently, there is no support for modifying schedules and neither do they appear in the state attributes.


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

Option 1: hub token only

  • requires a hub token obtained from
  • uses the v1 API - which is well-documented
  • polls Heat Genius’ own servers (so is slower, say 5-10s response time)
# Example configuration.yaml entry, using a Hub Token

Option 2: hub hostname/address with user credentials

  • requires your username & password, as used with
  • uses the v3 API - results are WIP and may not be what you expect
  • polls the hub directly (so is faster, say 1s response time)
# Example configuration.yaml entry, directly polling the Hub
  host: IP_ADDRESS

Note that if a host is used instead of token, then the username and password are also required.
