Set profile

Use this action to activate a ventilation profile on your Vallox unit, and optionally set how long it stays active.

Using this action from the user interface

If you prefer building automations and scripts visually, Home Assistant walks you through this action step by step. You pick what to target, tweak a few options, and save. No YAML knowledge required.

To set the profile from an automation or a script:

  1. Go to Settings > Automations & scenes.
  2. Open an existing automation or script, or select Create automation > Create new automation.
  3. If you’re setting up a new automation, add a trigger in the When section. Scripts don’t need a trigger. They run when something else calls them.
  4. In the Then do section, select Add action.
  5. Search for and select Vallox: Set profile.
  6. Set the Profile, and optionally a Duration.
  7. Select Save.

Options in the UI

Profile (Required)

The profile to activate: home, away, boost, fireplace, or extra.
Duration (Optional)

How long to keep the profile active, in minutes, between 1 and 65535. Only applies to the boost, fireplace, and extra profiles. A value of 65535 activates the profile without a timeout.
