Hey, I recently face the following problem: I wanted to share a smart Sonoff switch with my family using the native eWeLink app. At the same time I wanted to Integrate this smart switch with my local Home Assistant and Node Red installations. eWeLink + Home Assistant + Node-RED – I managed to find a solution and now I have the best from both worlds – Cloud and Local Sonoff at the same time. In this video post I want to show you how you can also do it step-by-step.

eWeLink + Home Assistant + Node-RED Other Possible solutions?
Initially I thought that I will just flash the Sonoff switch with Tasmota – https://youtu.be/_UnI6cnzF3k
or if you prefer to read
and then aI will setup a VPN client for everyone that I want to have access to my switch. While this approach will definitely do the job it’s seem that it will be too complicated. Setting a VPN on different devices – ones with iOS others with Android on top with different OS versions can be a real pain.
Then I immediately remember about ZeroTier for the VPN part – https://youtu.be/lFmeF5xoAPI
the full article can be found here
But even with ZeroTier, explaining to a non tech person what is VPN, then how to connect to it, then what to open and at the end how to turn on and off the switch is not an easy task. So I abandoned this idea for now and I start searching for other solution – eventually I found it.
eWeLink + Home Assistant + Node-RED Prerequisites:
- A Sonoff Device with the free eWeLink app installed and eWeLink account
- A Smashed Subscribe button
- Working Home Assistant or Node Red or better both
Setup:
Actually the solutions are two:
- For Home Assistant is called – HASS-sonoff-ewelink – https://github.com/peterbuga/HASS-sonoff-ewelink
- Create the following structure inside your Home Assistant configuration folder (the sonoff folder you can get from the GitHub repo above)
custom_components └── sonoff └── __init__.py └── switch.py └── sensor.py
- Add the following lines to your configuration.yaml file:
sonoff: username: [email or phone number] password: [password] scan_interval: 60 (optional, lower values than 60 won't work!) grace_period: 600 (optional) api_region: 'eu' (optional) entity_prefix: True (optional) debug: False (optional)
- For Node Red called – node-red-contrib-ewelink – https://github.com/ottoszika/node-red-contrib-ewelink
- Install the package by either using the Terminal/Command Prompt and run the following command in the Node-RED data directory:
$ npm install node-red-contrib-ewelink
- From Node-RED
Go to Menu → Manager palette → Install and search for node-red-contrib-ewelink and click install.
After that you could watch the video above and you can use the test flow that I created, but don’t forget to add your credentials and device ID:
