Morph effect

Use this action to run the firmware-based Morph effect, which animates blobs of color across the device. This is a hardware effect, so it only works on LIFX matrix lights such as the Tile, Candle, Path, Spot, and Ceiling.

You must provide either a palette or a theme to use for the effect, but not both. The palette lets you pick the exact colors, while the theme lets you choose one of the predefined themes that match those in the LIFX smartphone app.

By default, the light is turned on when the effect starts. Turn off the power on option to leave a light that is off untouched.

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 run the morph effect 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 LIFX matrix lights you want to animate.
6. From the actions shown for that target, select Morph effect.
7. Fill in the options you want to use.
8. Select Save.

Using this action 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, refer to this action as lifx.effect_morph. A basic example looks like this:

action: lifx.effect_morph
target:
  entity_id: light.lifx_tile
data:
  theme: exciting
  speed: 5

This starts the Morph effect on the LIFX Tile using the exciting theme.

Targets of the action

This action requires a target. The target is the object of the action. You can point the action 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 run the action on every matching light entity behind that target.

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

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