Server Bridge to control Sonoff Devices via MQTT This uses Sonoff stock firmware, no flashing required.
Version 2.0.0 Tested on Ubuntu 20.04, Python 3.8.
NOTE: This is a completely re-written version. The old version (V 1.x) is available in the old_version branch, but is no longer maintained as of 9th September 2022
This is a python 3.8 program and uses asyncio. you will need several libraries installed including
- asyncio
- paho-mqtt
- aiohttp
- zeroconf
- voluptuous
The eWelink authentication is based on the Home-Assistant SonoffLAN custom component. https://github.com/AlexxIT/SonoffLAN You Need to download this custom component to the eWeLink-mqtt directory - See Installation for details
I have only verified that e-mail logins works.
NOTE: The server only supports one eWeLink account where you can connect using your app email and password, or in place of the email you can use your phone number and password (but I have not tried phone number logins, or regions other that North America and Europe). Each time an eWeLink is logged in an authentication token is generated and you can only have one token per user, so after starting the server, you must keep your eWeLink account logged off. Otherwise, if you try to use eWeLink at the same time as the server with your paired devices, both applications will be contending for a login session and neither will stay online.
Alternatively, you can create a secondary account on eWeLink and your primary account to share devices with this secondary account. Then simply use the secondary account with the server and keep your primary account online with eWeLink without the risk of having the session expired because of the server running.
This applies to the Autoslide app as well if you use it.
Autoslide Patio Door Openers are Supported if you have the WiFi module
I wrote this bridge specifically to control my Autoslide patio Door opener, I just added all the other Sonoff stuff because it was easy. I do find that the Autoslide Controller goes off line from time to time, but you can still send it commands (like to trigger the door opening for "pet" or "auto" and changing modes), it's the feedback that seems to be the problem. Power cycling the door controller fixes it, but I'm hoping for an updated firmware from Autoslide (or Itead) to fix it. Current F/W is 2.7 (with no updates for a year or so).
Clone this repository:
git clone https://github.com/NickWaterton/eWeLink-mqtt.git
cd to eWeLink-mqtt:
cd eWeLink-mqtt
The server can be run by running ./ewelink.py now. The first time you run, the custom_components directory will be downloaded from https://github.com/AlexxIT/SonoffLAN/releases automatically.
To update the custom_components directory, delete the custom_components directory, and the latest version will be downloaded again when you run ewelink.py.
Clone this repository:
git clone https://github.com/NickWaterton/eWeLink-mqtt.git
Clone SonoffLAN:
git clone https://github.com/AlexxIT/SonoffLAN.git
or download a release from https://github.com/AlexxIT/SonoffLAN/releases
Copy the custom_components directory from SonoffLAN to eWeLink-mqtt:
cp -R SonoffLAN/custom_components eWeLink-mqtt
cd to eWeLink-mqtt:
cd eWeLink-mqtt
The server can be run by running ./ewelink.py now.
To update the custom_components directory, change to the SonoffLAN directory, and run git pull. Now copy the custom_components directory to eWeLink-mqtt as described above.
I included support for a number of basic devices, such as:
- Basic,Basic2 Switches
- Pow,Pow2,S31 Switches
- TH16,TH10 Switches
- 4CH Pro Switch
- B1 LED Bulb
- Autoslide Patio Door Controller
Anything not on this list will get added as a Basic switch (ie you get on and off control and feedback).

You set up an account using the ewelink app. Add all your Sonoff devices to the ewelink account as the app described (this can be a PITA, as Sonoff devices can be hard to add).
Now when you start ewelink.py with your account credentials and mqtt broker address, the devices values will be published to your mqtt broker, and you can send commands via mqtt messages.
The two tested regions are us (default) and eu.
Many standard devices are supported (built in). if you have an unsupported device, the default for a Basic switch is used. Most functions are supported, including timers etc. Feel free to add more functions/devices.
You send on or off to /ewelink_command/1000861ac4/switch to turn the switch on or off (or change any of the other settings or trigger parameters).
eg using Ubuntu and mosquitto
mosquitto_pub -t "/ewelink_command/1000861ac4/get_config" -m 0
mosquitto_pub -t "/ewelink_command/1000861ac4/switch" -m on
mosquitto_pub -t "/ewelink_command/1000861ac4/switch" -m off
and so on.
It is fairly easy to add new devices, you just add a <devicename>.py file (give it a unique name) in the devices directory with this format (this is the definition of the B1 bulb):
class LEDBulb(Default):
"""An eweclient class for connecting to Sonoff Led Bulb B1"""
productModel = ["B1"] #model list used for identifying the correct class
#this is available in self._productModel to allow different responses depending on the model created
triggers =[ ]
settings ={ "channel0": "white_cold", #"0-255", in colour mode (2) these are set to 0
"channel1": "white_warm", #"0-255", in colour mode (2) these are set to 0
"channel2": "red", #"0-255", regular RGB, in white mode (1), these are set to 0
"channel3": "green", #"0-255",
"channel4": "blue", #"0-255",
#These just seem to be indicators for the app, changing them makes no difference to the bulb
"state": "state", #"on","off", - this does turn the bulb on and off if changed, but does not report the state correctly
"type": "type", #"middle", "warm", "cold", setting of slider switch on app (does not change bulb)
"zyx_mode": "mode", #colour mode 2=colour, 1=white, mode setting in app (does not change bulb) this is a numerical value
}
other_params ={ "fwVersion": "fwVersion",
"rssi": "rssi",
"staMac": "staMac"
}
numerical_params=["zyx_mode"] #all basic parameters are assumed to be strings unless you include the parameter name here (in which case it's converted to an int)
timers_supported=[ 'delay', 'repeat', 'once']
__version__ = '1.0'
Give the class a meaningful name ('FanControler' or something), and fill in the data. You can see the names of the fields in the log of the bridge, just match them up with whatever you want then to be in mqtt.
You need to enter productModel correctly, this is how the device is identified.
EG: This is the class for the Pow, Pow2 and S31 Switches:
class PowSwitch(Default):
"""An eweclient class for connecting to Sonoff Switch with Power Monitoring"""
productModel = ["Pow","Pow2","S31"] #model list used for identifying the correct class
#this is available in self._productModel to allow different responses depending on the model created
triggers =[ "switch"]
settings ={ "sledOnline": "sledOnline", #'on', 'off'
"startup" : "startup", #'on', 'off'
"switch" : "switch" , #'on', 'off'
"alarmPValue": "alarmPValue", #Pow2 and S31 set Power Limit [min, max] -1 = off (this is a floating point value, min 0.1)
"alarmVValue": "alarmVValue", #Pow2 and S31 set Voltage Limit [min, max] -1 = off
"alarmCValue": "alarmCValue", #Pow2 and S31 set Current Limit [min, max] -1 = off
"alarmType" : "alarmType", #Pow2 and S31 report alarms set "p|v|c" (when tripped limit is reported as above) no alarm set is "pvc" oddly enough
"endTime" : "endTime", #ISO Zulu (UTC) Time
"hundredDaysKwh": "hundredDaysKwh", #'get', 'start', 'stop'
"oneKwh" : "oneKwh", #'get', 'start', 'stop'
"startTime" : "startTime", #ISO Zulu (UTC) Time
"timeZone" : "timeZone" #current timezone offset from UTC (EST= -5)
}
other_params ={ "init": "init", #int 1 (not sure what this is)
"power" : "power", #reported power consumption (W)
"voltage" : "voltage", #Pow2 and S31 reported Voltage (V)
"current" : "current", #Pow2 and S31 reported Current (A)
"fwVersion": "fwVersion",
"rssi": "rssi",
"staMac": "staMac"
}
timers_supported=[ 'delay', 'repeat', 'duration']
__version__ = '1.0'
And this is typical output from the server log (in debug mode):
[D 2020-04-06 15:35:07,262] (Main.EwelinkClient ) Received data: {

},

}
You can see that "current" in the json is set to publish to "current" in mqtt, and so on. As you change things in the app, you can watch the json,
and figure out what the parameters are, or send get_config to get them all.
This will publish the following:

To your mqtt server.
See ewelink_devices.py to see the definition of all the devices. Do NOT change Default as that is the base class for all devices!
