Lutron is an American lighting control company. The Lutron Homeworks Series 4 & 8 systems are relatively old (~2003), and use RS-232 connections to communicate with home automation systems. The
homeworks integration in Home Assistant is responsible for communicating with the main controller for these systems. Communication is through an ethernet to serial converter (NPort, for example).
Only a subset of the Homeworks system is supported - lights and keypads.
Lutron has created many systems over the years, each with their own unique interfacing protocol. There are three Homeworks systems - QS, Series 4 & 8, and original. This platform is only for Series 4 & 8. There is another integration lutron which handles Lutron RadioRA 2 systems.
Homeworks keypad buttons are momentary switches. The button is pressed and released, meaning that there is no “state”. Buttons generate
homeworks_button_release events. These events contain the “id”, “name”, and “button” of the button that was pressed. “id” is derived from “name”, and “button” is the number of the button on the keypad (starting at 1).
The protocol for automatically extracting device information from the controller isn’t documented, so the
homeworks integration must be configured manually. To use Lutron Homeworks devices in your installation, add the following to your
# Example configuration.yaml entry homeworks: host: IP_ADDRESS port: 4001 dimmers: - addr: "[02:08:01:01]" name: "Foyer Sconces" - addr: "[02:08:01:02]" name: "Foyer Downlights" rate: 2 keypads: - addr: "[02:08:02:01]" name: "Foyer Keypad"
The IP address of the ethernet to serial adapter. It is assumed that the adaptor has been preconfigured.
The port of the ethernet to serial adapter.
List of dimmers.
The unique address of the dimmer on the controller. The quotes, brackets, and number formatting must be of the form
The name of the sensor will be the title of the button +
"_"+ the name of the keypad/
The amount of time (in seconds) for the light to transition to a new brightness level.
List of keypads.
