Broadlink RM server for IFTTT

Broadlink RM Server for IFTTT control

This is a simple server that allows you to connect your Broadlink (tested with the RM mini 3) to your IFTTT account.

Setup

• Get a IFTTT account and enable the Maker Webhooks: https://ifttt.com/maker_webhooks
• Download and install ngrok: https://ngrok.com/
• Install this repository by running npm install broadlink-rm-server

Running with NPM

Create a file named index.js and add the following code:

"use stict";
const PORT = process.env.PORT || 1880;

const BroadlinkServer = require('broadlink-rm-server');
const commands = require('./commands');

let app = BroadlinkServer(commands);
    app.listen(PORT);

console.log('Server running, go to http://localhost:' + PORT);

Create a file named commands.js and add:

module.exports = [];

Configure this commands.js file with your commands and IP/Mac address of the BroadlinkRM (see below).

Now run node index and the server should start. You will see in the console your Broadlink IP address, we will use it later.

Learn IR codes

Learning codes is now built in with the server, in order to enable it, edit your index file and modify the line:

let app = BroadlinkServer(commands);

After commands, set TRUE to enable the learning mode.

let app = BroadlinkServer(commands, true);

Now run the server with node index and open your browser, go to your server url and add /learn/command/MAC_OR_IP, point your remote to the Broadlink and press the key you want to attach to the command. You will get a response like this:

{
    command: "Projector",
    secret: "dnja9kdtn",
    mac: "34:ea:34:bb:16:1a",
    ip: false,
    data:"260058000001289413121213111413121213111413121114113911391238113911391238111412381114123811141213111411141212121410391214103912391237113912391237110005490001264b12000c5e0001264b11000d05"
}

Add this command to your command.js array and save. Remember to disable the learning mode by removing the true or setting it to false.

Ngrok

In order to connect IFTTT to the PC/server running this code (like a Raspberry Pi), you will need a URL that tunnels to your device, this is done with ngrok.

After installing ngrok, run: ngrok http 1880

IFTTT

For this instructions I'm going to setup my Google Home with the Broadlink, on IFTTT search for Google Assistant and enable it (https://ifttt.com/google_assistant). Then, create a new applet: https://ifttt.com/create.

Trigger setup

• Click on +this and search for the Google Assistant.
• Select Say a simple phrase
• Set What do you want to say? with a command like "TV on".
• Set What do you want the Assistant to say in response? with a custom response like "Turning the TV on"
• Click on Create trigger

Action setup

• Click on +that and search for Maker Webhooks
• Select Make a web request
• In the URL field, set your Ngrok URL and add at the end /command/YOUR_COMMAND_NAME
• Method should be POST
• Content Type select application/json
• For the body set: {"secret":"YOUR_COMMAND_SECRET_HERE"}
• Click Create Action

You should now be able to say Ok Google, TV ON and IFTTT will send a request to your local server that will relay the action to the Broadlink and turn on your TV!.
