Tado

The Tado integration platform is used as an interface to the my.tado.com website.

There is currently support for the following device types within Home Assistant:

• Binary Sensor - for some additional information of the zones.
• Climate - for every Tado zone.
• Water Heater - for water heater zones.
• Presence Detection
• Sensor - for some additional information of the zones.
• Weather - for information about the current weather at the location of your Tado home.

Configuration

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

Tado 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 Tado thermostats are internet connected thermostats. There exists an unofficial API at my.tado.com, which is used by their website and now by this component.

It currently supports presenting the current temperature, the setting temperature and the current operation mode. The operation mode can be set to manual, auto and off. If no user is at home anymore, all Tado zones show the away-state (Only with Tado assist mode). Manually switching between home-mode and away-mode is also supported. Manually switching to auto-mode is only supported with Tado assist mode. Any Tado climate card can be switched between these presence modes, this changes the setting for the entire home.

Presence Detection

The tado device tracker is using the Tado Smart Thermostat and its support for person presence detection based on smartphone location by geofencing.

This tracker uses the Tado API to determine if a mobile device is at home. It tracks all devices in your home that Tado knows about.

To use the Tado platform in your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry for Tado
device_tracker:
  - platform: tado
    username: YOUR_USERNAME
    password: YOUR_PASSWORD
    home_id: YOUR_HOME_ID

After configuration, your device has to be at home at least once before showing up as home or away. Polling Tado API for presence information will happen at most once every 30 seconds.

See the device tracker integration page for instructions how to configure the people to be tracked. Beware that the Tado (v2) API does not provide GPS location of devices, only a bearing, therefore Home Assistant only uses home/not-home status.

Finding your home_id

Find your home_id by browsing to https://my.tado.com/api/v2/me?username=YOUR_USERNAME&password=YOUR_PASSWORD. There you’ll see something like the following:

{
  "name": "Mark",
  "email": "[email protected]",
  "username": "[email protected]",
  "homes": [
    {
      "id": 12345,
      "name": "Home Sweet Home"
    }
  ],
  "locale": "en_US",
  "mobileDevices": []
}

In this example 12345 is the home_id you’ll need to configure.

Finding your home_id alternative

If the above method returns an unauthorized error. The home_id can also be found using Chrome developer tools. Whilst logged into https://my.tado.com/webapp, take the following steps:

• Select the “Network”’ tab
• Filter for “home”
• Under “Name”, select “users”
• Click on the “Response” tab

The home_id appears in the response for users as "id":12345

In this example 12345 is the home_id you’ll need to configure.

Services

Service tado.set_climate_timer

You can use the service tado.set_climate_timer to set your Tado climate device, for example a radiator valve, to switch on for a set time period.

Service tado.set_water_heater_timer

You can use the service tado.set_water_heater_timer to set your water heater to switch on for a set time period.

Service tado.set_climate_temperature_offset

You can use the service tado.set_climate_temperature_offset to set the temperature offset for Tado climate devices.

    # Work out what the new offset should be (tado temp less the room temp but add the current offset value) and turn that to a negative value for setting as the new offset
