All lights and wall switches are wired to a central panel. This central panel has a sierial port interface that allows a computer to control the system via LiteJet's third party protocol. Home Assistant integrates the LiteJet 3rd party protocol and allows you to get the status and control the connected lights. After connecting the LiteJet's RS232-2 port to your computer, add the following to your `configuration.yaml`: ```yaml litejet: url: /dev/serial/by-id/THE-PATH-OF-YOUR-SERIAL-PORT ``` Your LiteJet MCP should be configured for 19.2 K baud, 8 data bits, 1 stop bit, no parity, and to transmit a 'CR' after each response. These settings can be configured using the [LiteJet programming software](https://www.centralite.com/helpdesk/knowledgebase.php?article=735). You can also configure the Home Assistant to ignore lights, scenes, and switches via their name. This is highly recommended since LiteJet has a fixed number of each of these and with most systems many will be unused. ```yaml litejet: exclude_names: - 'Button #' - 'Scene #' - 'Timed Scene #' - 'Timed Scene#' - 'LV Rel #' - 'Fan #' ``` Configuration variables: - **url** (*Required*): The path to the serial port connected to the LiteJet. - **exclude_names** (*Optional*): A list of light or switch names that should be ignored. - **include_switches** (*Optional*): Cause entities to be created for all the LiteJet switches. Default is false. This can be useful when debugging your lighting as you can press/release switches remotely.
