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.
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.

## Prerequisites
After connecting the LiteJet's RS232-2 port to your computer, add the following to your `configuration.yaml`:
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). Connect the LiteJet's RS232-2 port to your computer.
```yaml
litejet:
port: /dev/serial/by-id/THE-PATH-OF-YOUR-SERIAL-PORT
```
{% include integrations/config_flow.md %}

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.
{% configuration %}
port:
description: The path to the serial port connected to the LiteJet.
required: true
type: string
exclude_names:
description: A list of light or switch names that should be ignored.
required: false
type: [list, string]
include_switches:
description: Cause entities to be created for all the LiteJet switches. This can be useful when debugging your lighting as you can press/release switches remotely.
required: false
default: false
type: boolean
{% endconfiguration %}
```yaml
litejet:
exclude_names:
- 'Button #'
- 'Scene #'
- 'Timed Scene #'
- 'Timed Scene#'
- 'LV Rel #'
- 'Fan #'
```
By default only light entities will be enabled. Scene and switch entities can be individually enabled on the integration's entity list page.
### Trigger
LiteJet switches can be used as triggers too to allow those buttons to behave differently based on hold time. For example, automation can distinguish quick tap versus long hold.

- **platform** (*Required*): Must be 'litejet'.
- **number** (*Required*): The switch number to be monitored.
