Package Exports

homebridge-rtl

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (homebridge-rtl) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

homebridge-rtl

Homebridge plugin to display information from 433 Mhz sensors, like the Skylink HA-434TL motion sensor or the AcuRite Digital Wireless Fridge and Freezer Thermometer temperature sensor. This plugin uses the RTL_433 package to listen to the sensor in-conjunction with a sdr device to receive the signals from the sensor. In my setup I use this RTL_SDR to receive the radio signal from the sensor.

For sensors, I'm using these

Fridge Temperature
Motion
Supported sensors include Motion and Temperature
Also shows "not responding" if the sensor stops sending data

I have tested this on both a Mac and a RPI3

Installation

Install Homebridge using sudo npm install -g homebridge
Install this plugin sudo npm install -g homebridge-rtl
Install RTL_433 following the instructions here
Configure homebridge

Configuration

platform: "rtl_433"

id: id number of device - To find the ID of your device, run homebridge in DEBUG mode, and it will log the message received from all rtl_433 devices. See below for examples
type: Type of sensor device. Supported sensors are motion and temperature

Example configuration:

"platforms": [{
    "platform": "rtl_433",
    "devices": [
      {
      "id": "1e3e8",
      "name": "Front Porch",
      "type": "motion"
      }]
  }]
