eWeLink has officially integrated with SmartThings

@Mikeyf79 did you have to pay for any special access to add your sonoff devices to ST?

None, its all now integrated.
Just goto add new device in Smartthings, select ewelink switch or light (cant remember which i selected). It will ask you to link accounts and then all existing devices get imported.


I stumbled around for a bit, thinking that I had to add a specific device. You really just need to select ewelink Smart Home from any of the device options.

@Automated_House Thanks for your comments. It’s a cloud-to-cloud integration.

The linking process is quite simple.
Add eWeLink compatible devices to the SmartThings app. >

@Olli-Pekka_Kurppa Technically, you can add most eWeLink compatible switches, outlets, lights, Zigbee sensors.

3 Gang Sonoff switches show up in ST as individual switches. Temp and humidity did not show up for me with Sonoff switches that have it. They show up if you flash them and use erocm1231’s handler and app.

How are the Zigbee sensors handled? Is another hub needed (cloud to cloud integration) or are those directly connected to ST hub? I’m thinking about devices like Sonoff Zigbee door sensor.

WiFi sockets join by c2c as expected, would imagine zwave zigbee items join by either brand selection or general inclusion
Minimum would be c2c

Basically there is two connection types : eWeLink (direct connection, asks to press pairing button on device) and eWeLink Smart Home (asks to login to eWeLink cloud).
Lighting is cloud only. Motion, open/closed and Outlet are direct. Switch/dimmer has both plus Zigbee.
Does it mean that Wifi sensors or outlets could connect directly to ST?
@fido Have you actually connected Wifi socket using this? Type outlet or switch/dimmer selected?
I’m just trying to make sense all of this. Currently, I do not have any commercial Wifi devices on ST.

I use a couple of wifi plugs that use the ewelink app, connected through c2c no issues although not all the available info available in the ewelink app is surfaced within ST


I just tested a Sonoff TH16 with DS18B20 temperature sensor. Switch response in SmartThings is functional and very fast.

There is no discovery of the sensor in SmartThings. The sensor works fine in the eWeLink app. This kinda makes sense because when adding a device in the SmartThings app (by brand, eWeLink), there are only 5 device types to choose from:

  • Lighting
  • Motion sensor
  • Open/closed sensor
  • Outlet
  • Switch/dimmer (which I chose when adding the TH16)

This is how the device appears in the ST IDE:

Name c2c-switch
Label Freezer Thermometer
Type placeholder

All new cloud-to-cloud integrations have Type = placeholder, so the IDE looks correct. Most likely eWeLink developed and owns the integration, so requesting new features through them is probably the best route.


I’ve been in touch with sonoff and they said they are working on additional features like the TH16 and will be added later.


Hi Mate,

I think you can use all linked device in ewelink app by using the eWelink Smart Home cloud config in smartthings.


No, as I said I’ve been talking with sonoff and you cant yet. You can see things like the TH16 but you can’t get temperature or humidity readings yet. So in smartthings you can see the state of the switch but not the thing your monitoring.

I have a few Sonoff Basic in-line switches which are used to control LED lights around the house. Anyone know how to make them show up as lights in ST instead of switches? In Alexa app, I can just switch the Type from “Plug” to “Light”.

are you referring to the icon in the app? Currently that can’t be changed.

Yes. However, I was under the mistaken impression that you could not add switches to a light group, but you can so it’s not a pressing issue.

can Sonoff T3 wifi smart switches be integrated with smartthings

@A.N.M_Samiul_Alam, yes.

I have a T1 US switch working fine using the Tasmota firmware and this Device Handler [RELEASE] Tasmota (Connect) for Sonoff, Tuya, SmartLife & other ESP8266 devices).

I believe the process is similar for the T3.
