Send command

The Send command action sends a custom command to your Lutron Homeworks controller. You can send a single command or a list of commands.

This action does not target an entity. Instead, you provide the controller to send to and the command to send.

In addition to the commands supported by the controller, the special command DELAY <ms> is supported, where <ms> is the number of milliseconds to wait before continuing.

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 send a command 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. From the search box, search for and select Lutron Homeworks: Send command.
6. Enter the Controller ID and the Command to send.
7. 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 homeworks.send_command. A basic example looks like this:

action: homeworks.send_command
data:
  controller_id: "homeworks"
  command: "KBP, [02:08:02:01], 1"

This sends a single command to the controller.

Options in YAML

Good to know

To send several commands in sequence, pass a list. The following example sends KBP, waits 0.5 seconds, then sends KBR to simulate a keypad button press that lasts half a second:

action: homeworks.send_command
data:
  controller_id: "homeworks"
  command:
    - "KBP, [02:08:02:01], 1"
    - "DELAY 500"
    - "KBR, [02:08:02:01], 1"
