General-purpose program for showing statistics on a Raspberry Pi with an LCD display.

An example configuration can be found in example-config.json.

npm run build
npm start /path/to/config.json

• You don't have to switch or scroll the status text yourself. The hard part is done for you.
• You can show any statistic or text you want on the LCD screen using any program you want. rpi-lcd-server has an HTTP API which can be accessed on port 8485 by default, making it easy to add or update statistics on the screen.

All requests that have a body must have the content type application/x-www-form-urlencoded.

Gets the current status for the specified service.

{
  "value": "294 req/hr",
  "lastUpdate": "2021-09-21T15:58:06.456Z",
  "expireDate": "2021-09-21T16:00:06.456Z"
}

Returns all active services and the index for the service that is currently being displayed on the LCD screen.

{
  "services": [
    "my-web-server",
    "my-bluetooth-service"

}
