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 exactly match that of the official Web App.

Prerequisites

You can configure the integration either via the cloud API or the local API.

• Cloud API: requires a hub token obtained from my.geniushub.co.uk.
• Local API: requires your username and password as used with geniushub.co.uk/app.

The local API is unofficial, but is faster and has more features, while the cloud API is slower.

Configuration

To add the Genius Hub integration to your Home Assistant instance, use this My button:

Zones

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 and
• Switch entity, for On/Off zones

Group zones are not supported.

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

There are limitations due to the differences between the Genius Hub and Home Assistant schemas (for example, Home Assistant has no Footprint mode) - use the actions below, for this functionality.

Action handlers

Home Assistant is obligated to place restrictions upon integrations such as geniushub to maintain compatibility with other ecosystems (e.g., Google Home) and so not all of the geniushub functionality is available via the web UI. Some of this missing functionality is exposed via integration-specific actions:

• set_switch_override: change the switches on time for a specified duration (up to 24h),
• set_zone_override: change the zone’s setpoint for a specified duration (up to 24h), and
• set_zone_mode: change the zone’s mode to one of off, timer or (if supported by the zone) footprint

Climate and water heater entities

Climate and water heater entities will report their current temperature, setpoint and mode; other properties (e.g., occupied state) are available via their state attributes (see examples below). The Genius Hub mode will be reported as/set to:

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

Switch entities

Switch entities will report back their state; other properties are available via their state attributes. Currently, HA switches do not have modes/presets, so the Home Assistant state will be reported as:

• On for Override \ On, and
• Off otherwise (NB: the zone could still be ‘on’, e.g., with Timer mode)

Note: if you turn a Switch entity Off via Home Assistant’s web UI, it will revert to Timer mode - this may not be the behavior you are expecting.

Individual smart plugs are not yet exposed as switches - you can create one zone per smart plug as a work-around.

Devices

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)

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

Issues

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"
  triggers:
    - trigger: numeric_state
      entity_id: sensor.geniushub_errors
      above: 0
  actions:
    - action: notify.pushbullet_notifier
      data:
        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"
  triggers:
    - trigger: state
      entity_id: binary_sensor.dual_channel_receiver_2_1
  actions:
    - action: notify.pushbullet_notifier
      data:
        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 the corresponding 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 }}"
