Controlling hot water (Tado) with google assistant

Hi all,

I’m having some trouble with exposing my HA-controlled water heater to Google Assistant. I’ve followed the guide at Google Assistant - Home Assistant to connect Google to my HA instance which is working fine: I’m able to control lights, input_booleans etc by voice.

However, I can’t seem to make Google detect my water heater. I use Tado for heating and hot water: the heating works fine, but the hot water controls don’t appear in the Google Home app. Here’s the relevant part of my config:

google_assistant:
  project_id: my-google-project-id
  service_account: !include secret_files/google_service_account.json
  report_state: true
  expose_by_default: true
  exposed_domains:
    - switch
    - climate
    - vacuum
    - light
  entity_config:
    water_heater.hot_water:
      name: Hot water

Any ideas?
