Toggle humidifier

Use this action to toggle a humidifier, dehumidifier, or hygrostat, switching it on if it is off and off if it is on.

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 toggle a humidifier 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. Select what you want to control. Under By target (see Targets), select the humidifier you want to toggle.
  6. From the actions shown for that target, select Toggle humidifier.
  7. Select Save.

Options in the UI

This action has no additional options beyond the target.
