Genius Hub

The geniushub integration links Home Assistant with your Genius Hub CH/DHW system, including its zones, devices, and issues.

It uses the geniushub client library, which provides data compatible with the v1 API that may not necessarily match that of the official Web App.


Each zone controlled by your Genius Hub will be exposed as either a:

  • Climate entity, for Radiator and Wet Underfloor Zones, and
  • Water Heater entity, for Hot Water Temperature Zones

Other zone types, such as On/Off zones, are not currently supported (although see Binary Sensors, below).

Each entity derived from a GH zone will report back its mode, setpoint and current temperature; other properties are available via its attributes (see below). The zone’s mode can be changed as below.

GH mode HA Operation HA Preset
Off Off N/A
Timer Heat None
Override Heat Boost
Footprint Heat Activity

Note that Footprint mode is only available to Radiator zones that have room sensors.

Currently, there is no support for reading/altering zone schedules, although a zone can be switched to/from modes that utilize schedules.


Each Device controlled by your Genius hub will be exposed as either a:

  • Sensor entity with a % battery, for any Device with a battery (e.g., a Genius Valve), or
  • Binary Sensor entity with on/off state for any Device that is a switch (e.g., Smart Plugs, DCRs)

Each such entity will report back its primary state and assigned_zone. If the Hub is directly polled using Option 1 (see below), then some additional attributes such as last_comms (last communications time) are also available.


There are three Sensor entities that will indicate the number of Errors, Warnings and Information issues.

Each such entity has a state attribute that will contain a list of any such issues which can be used in automations, etc. For example:

- alias: GeniusHub Error Alerts
    platform: numeric_state
    entity_id: sensor.geniushub_errors
    above: 0
  - service: notify.pushbullet_notifier
      title: "Genius Hub has errors"
      message: >-
        Genius Hub has the following {{ states('sensor.geniushub_errors') }} errors:
        {{ state_attr('sensor.geniushub_errors', 'error_list') }}

This alert may be useful to see if the CH is being turned on whilst you’re on a holiday!

- alias: GeniusHub CH State Change Alert
    platform: state
    entity_id: binary_sensor.dual_channel_receiver_2_1
  - service: notify.pushbullet_notifier
      title: "Warning: CH State Change!"
      message: >-
        {{ trigger.to_state.attributes.friendly_name }} has changed
        from {{ trigger.from_state.state }} to {{ trigger.to_state.state }}.

State Attributes

Many zone/device properties are available via each entity’s state attributes. For example, in the case of Radiator-derived Climate entities (note ‘status’):

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

… and for Genius Valve-derived Sensor entities (note ‘state’):

  "state": {
    "set_temperature": 4.0,
    "measured_temperature": 20.030000686645508,
    "setback": 3.5,
    "wakeup_interval": 450

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

value_template: "{{ state_attr('water_heater.genius_zone_2', 'status').override.setpoint }}"

In the specific case of Radiator zones with room sensors:

value_template: "{{ state_attr('climate.genius_zone_12', 'status').occupied }}"


To set up this integration, add one of the following to your configuration.yaml file.

If required, you can switch between one Option and the other and, as the unique_id remains consistent, state history will be preserved. This assumes that the correct MAC address is provided for Option 2, below. If a wrong MAC address was provided for Option 1, then the MAC address can be overridden for Option 1 to maintain these links within the entity registry.

Option 1: hub hostname/address with user credentials

This is the recommended option.

  • Requires your username & password, as used with
  • Uses the v3 API - unofficial, but there are additional features (e.g., battery levels).
  • Polls the hub directly (so is faster, say ~1s response time).
  • You have the option of specifying a MAC address.

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

Option 2: hub token only

This option is recommended only if Ootion 1 does not work. The MAC address should match that written on the back of the Hub.

  • 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).
  • You should use the Hub’s MAC address (although any valid MAC will do).
# Example configuration.yaml entry, using a Hub Token
# Example configuration.yaml entry, directly polling the Hub
  host: IP_ADDRESS

Configuration Variables



The Hub Token of the Genius Hub.



The MAC address of the Hub’s ethernet port.



The hostname/IP address of the Genius Hub.



Your Genius Hub username.



Your Genius Hub password.

Note: username and password are only required when host is used (instead of token).

Note: mac is required if token is used (instead of host) and is optional otherwise.
