Humidifier target humidity

The Humidifier target humidity condition passes when a humidifier entityAn entity represents a sensor, actor, or function in Home Assistant. Entities are used to monitor physical properties or to control other entities. An entity is usually part of a device or a service. [Learn more]’s target humidity setting meets a threshold you define. The target humidity is the setpoint you configure on the device, not the actual current humidity reading from its sensor. For example, you can use it to turn on a ventilation fan when the humidifier is set to 70% or above.

When you target more than one humidifier, the condition’s Condition passes if option controls how the check combines results. You can require any targeted humidifier to meet the threshold, or demand that all of them do.

Labs

Requires the Purpose-specific triggers and conditions Labs preview feature. Enable it at Settings > System > Labs.

Using this condition from the user interface

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

To use Humidifier target humidity in an automation:

  1. Go to Settings > Automations & scenes.
  2. Open an existing automation, or select Create automation > Create new automation.
  3. In the And if section, select Add condition.
  4. Select what you want to check. Under By target (see Targets), pick the area your humidifier is in (like your bedroom or living room). You can also select a device, a specific entity, or a label.
  5. From the conditions shown for that target, select Humidifier target humidity.
  6. Under Threshold type, set the comparison direction (Above, Below, In range, or Outside range) and the threshold value.
    • Choose Number to enter a fixed humidity percentage between 0 and 100, or Entity to use a humidity sensor or input number as the threshold.
  7. Under Condition passes if (see Behavior), pick Any or All to control how the check behaves when multiple humidifiers are targeted.
  8. Under For at least, set how long the humidifier must have been at the threshold before the condition passes. Leave it at zero to pass immediately.
  9. Select Save.

Options in the UI

Threshold type

Controls how the target humidity is compared and where the threshold value comes from. Use Above, Below, In range, or Outside range to set the comparison direction. Then choose Number to enter a fixed percentage between 0 and 100, or Entity to use a humidity sensor or input number as the threshold value.

Condition passes if

When multiple humidifiers are targeted, controls how results combine. Pick Any to pass if at least one targeted humidifier meets the threshold, or All to pass only when every targeted humidifier does. Default is Any.

For at least

How long the humidifier must have continuously met the threshold before the condition passes. Default is 0 (passes immediately).

Using this condition in YAML

If you work directly in YAML, or you want to know exactly what Home Assistant does under the hood, this section has the technical reference. It lists the field names you use in YAML, their types, and which ones are required.

In YAML, Humidifier target humidity is referred to as humidifier.is_target_humidity. A basic example looks like this:

ConditionConditions are an optional part of an automation that will prevent an action from firing if they are not met. [Learn more]
condition: humidifier.is_target_humidity
target:
  entity_id: humidifier.bedroom
options:
  threshold:
    above: 50

This passes when the bedroom humidifier’s target humidity is set above 50%.

Options in YAML

threshold map

The threshold to check the target humidity against. Accepts a mapping with the comparison direction as the key and the humidity percentage (0–100) as the value. Use above, below, or both (above and below together for a range) as keys. Instead of a fixed number, you can reference a sensor, input_number, or number entity as the value.

behavior string

When multiple humidifiers are targeted, controls how results combine. Accepts all or any.

for string

How long the humidifier must have continuously met the threshold before the condition passes. Accepts a duration string in HH:MM:SS format.

Targets of the condition

This condition requires a target. The target is the object that Home Assistant will check. You can point the condition at a single entityAn entity represents a sensor, actor, or function in Home Assistant. Entities are used to monitor physical properties or to control other entities. An entity is usually part of a device or a service. [Learn more], a device, an area, a floor, or a label, and Home Assistant will evaluate every matching humidifier entity behind that target.

  • Entity: one specific humidifier entity, such as humidifier.living_room.
  • Device: every humidifier entity that belongs to a device.
  • Area: every humidifier entity in a room or area.
  • Floor: every humidifier entity on a floor.
  • Label: every humidifier entity that shares a label.

You can also select different target types in one condition. For example, you can add a specific entity and an area as targets in the same condition to check both of them at once.

Behavior with multiple targets

When you target more than one entity (or select an area, floor, or label that contains several), the Condition passes if option controls how the results combine:

  • Any (default): the condition passes if at least one of the targeted entities matches. For example, if you check three smoke sensors and only one of them detects smoke, the condition still passes. This is useful for questions like “is there smoke anywhere in the house?”
  • All: the condition passes only when every targeted entity matches. For example, if you check the same three smoke sensors, the condition passes only once all three report cleared. This is useful for “is the entire house safe now?” checks, so your automation does not send an all-clear while one room still has a reading.

Good to know

  • This condition checks the humidifier’s target humidity setpoint, not the actual measured humidity in the room. To react to the measured humidity, use a sensor-based numeric condition instead.
  • Humidifiers that are unavailable (unavailable) or have an unknown state (unknown) are skipped for Any and fail for All.
  • Target humidity is expressed as a percentage. The valid range depends on the device, but is typically between 20% and 90%.

Try it yourself

Ready to test this? Go to Settings > Automations & scenes, open an automation, and add this condition. Trigger the automation with and without the condition met, and watch whether it continues or stops.

Tip

You don’t need to edit YAML to use these examples. Copy a YAML snippet from this page, open the automation editor in Home Assistant, and press Ctrl+V (or Cmd+V on Mac). Home Assistant automatically converts the pasted YAML into the visual editor format, whether it’s a full automation, a single trigger, a condition, or an action.

Automation: turn on the ventilation fan when the humidifier is set high

When the bedroom humidifier’s target humidity is set to 70% or above, turn on the ventilation fan to reduce the risk of condensation. This keeps air circulating whenever the humidifier is running at a high setting.

  • Trigger: State change of the bedroom humidifier’s humidity attribute
  • Condition: Humidifier target humidity (70% or above)
  • Target: Bedroom humidifier
  • Condition passes if: Any
  • Action: Switch: Turn on ventilation fan

AI assistants like ChatGPT or Claude can also explain conditions or suggest the right one when you describe what you want in plain language.
