Para integrar interruptores sonoff com firmware original, você irá precisar do homebrige como ponte , veja neste artigo como instalar o homebridge.

Após instalar o homebridge, você irá precisar configura-lo para conectar-se a api da ewlink através do plugin homebridge-ewlink-max.

Como instalar o homebridge-ewelink-max

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 continue to use the OEM functionality (eWeLink app, Google Home integration); this plugin requires no modification to the relay’s firmware.

Why max?

This is a fork of homebridge-ewelink, which is not being actively updated. There is another package named homebridge-ewelin-plus which is not updated for 6 months at the time of writing. The name is inspired by Apple’s naming convention.

This fork have the following notable changes / improvements:

• Support login with phone number / email and password, which save your time from obtaining the authentication token with Charles once in a while.
• Support sending heartbeat on the WebSocket connection, which greatly reduce the interval of reconnects, hence better stability.
• Support obtaining the correct API / WebSocket API host automatically, so you don’t need to obtain these information with Charles.

Shortcomings

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-max

1. Add to the platforms[] section of config.json.

• phoneNumber – The login phone number of your ewelink account, do not include this if you login with email
• email – The login email of your ewelink account, do not include this if you login with phone number
• password – Your ewelink account login password
• imei – This can be any valid UUID, get one with an online generator

1. 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",
            "phoneNumber" : "+12345678901",
            "password" : "your-login-password",
            "imei" : "01234567-89AB-CDEF-0123-456789ABCDEF"
        }
    ]
}

If you use email login, the platform section should look like this:

        {
            "platform" : "eWeLink",
            "name" : "eWeLink",
            "email" : "your-email@example.com",
            "password" : "your-login-password",
            "imei" : "01234567-89AB-CDEF-0123-456789ABCDEF"
        }

A note on login session

An authentication token is generated every time your device’s app logs in to the eWeLink service.

You can only have one authentication token per user account.

Therefore if you use the HomeKit app and eWeLink app at the same time, they will fight each other for the login session. They should both work individually. You can leave homebridge running when using the eWeLink app.

To avoid being logged off from the eWeLink app

1. Create another account
2. Then log in with the new account on another mobile device (you have to keep both accounts connected and with eWeLink on the screen).
3. Go to your eWeLink, select your Sonoff device and share it with the other account.
4. A popup should appear on the other mobile device, accept it.
5. Use the second account as your plugin login (and never use this account on eWeLink anymore to avoid being logged off)
6. Be happy and never get a “session expired” message again.

Troubleshooting

I’ve attempted to make the logging as useful as possible. If you have any suggestions, please open an issue on GitHub.

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

Feito isso, basta adicionar o homebridge ao seu aplicativo apple casa.

1. Dirija-se ao seu dispositivo iOS e inicie o aplicativo CASA
2. Toque no botão Adicionar no canto superior direito da tela (parece um sinal de mais).
3. Toque em Adicionar acessório .
4. Toque no acessório Homebridge (o meu acabou de se chamar Homebridge).
5. Você verá um alerta que diz: “Este acessório não é certificado e pode não funcionar de maneira confiável com o HomeKit”. toque em Adicionar mesmo assim .
6. Toque em Inserir código manualmente na parte inferior da tela.
7. Digite o código do HomeKit para o seu acessório Homebridge. Você pode encontrá-lo na janela do Terminal abaixo do texto que diz “Digitalize este código com seu aplicativo HomeKit no seu dispositivo iOS para parear com o Homebridge”.
8. Adicione seu acessório Homebridge e toque em Avançar .
