LiteJet is a centralized lighting system that predates most home automation technology. All lights and wall switches are wired to a central panel. This central panel has a serial 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:
|
|
port: /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:
|
|
```
|
|
|
|
Configuration variables:
|
|
|
|
- **port** (*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.
|
|
|
|
|
|
|
|
```yaml
|
|
litejet:
|
|
exclude_names:
|
|
- 'Button #'
|
|
- 'Scene #'
|
|
- 'Timed Scene #'
|
|
- 'Timed Scene#'
|
|
- 'LV Rel #'
|
|
- 'Fan #'
|
|
```
