Homebridge-ewelink-complete NPM

This is a fork of homebridge-ewelink

The largest change here is to use evelink-api for all API needs rather than rewrite

homebridge-ewelink-complete

Homebridge plugin to control Sonoff relays with OEM firmware. It uses the same API as the iOS app to communicate with your devices.

The platform will dynamically add/remove devices based on what is configured in your eWeLink account.

It has been tested with the Sonoff basic relays. I have performed testing with up to two relays associated to my account.

The plugin will only support one eWeLink account.

It is possible to continute to use the OEM functionality (eWeLink app, Google Home integration); this plugin requires no modification to the relay's firmware.

Shortcomings

The plugin uses the same credentials as the eWeLink app. In order to obtain the authenticationToken, you'll need to use Charles to inspect the traffic and grab the value from the Authorization header. See below for information on how to obtain this value.

Also, the code is of suboptimal quality. It was a quick-and-dirty plugin; feel free to contribute & improve.

Steps to install / configure

Assuming that you've already downloaded the eWeLink app on your iOS device & have configured it:

1) Install the plugin

sudo npm -g install homebridge-ewelink-complete

2) Add to the platforms[] section of config.json. Steps for obtaining the values for authenticationToken, apiHost, and webSocketApi can be found below.

3) Restart Homebridge

Sample config.json

{
    "bridge": {
        "name": "Homebridge",
        "username": "XX:XX:XX:XX:XX:XX",
        "port": 51826,
        "pin": "123-45-678"
    },
    
    "description": "Your description here",

    "accessories": [
    ],

    "platforms": [
 {
            "platform": "eWeLink",
            "name": "eWeLink",
            "phoneNumberOrEmail": "YOUR_ACCOUNT_EMAIL_OR_PHONE",
            "accountPassword": "YOUR_ACCOUNT_PASSWORD",
            "apiHost": "us-api.coolkit.cc:8080",
            "webSocketApi": "us-long.coolkit.cc",
            "debug": "true"
        }    ]
}

A note on the authenticationToken

The authentication token is generated every time your device's app logs in to the eWeLink service. Based on my limited testing, the session seems to persist for quite some time.

You can only have one authentication token per user account.

If you logout and login to the app again, you'll need to perform the above steps to get things working again.

Troubleshooting

I've attempted to make the logging as useful as possible. If you have any suggestions, please open an issue on GitHub. I've also hidden most logging behind the debug parameter, please set to true or false accordingly

The plugin will also listen for announcements via a persistent web socket. This allows you to control the device from the likes of Google Home & have Homebridge be kept up-to-date
