(Updated) Last update broke the app for me

Last update made the app very unreliable for me. I open the app and I see all my devices but when I tap on them they just don’t respond. Force closing the app sometimes gets them to work. I have Siri shortcuts set through ifttt. They work reliably. I also have voice commands through google home mini that work reliably. It’s just the eWeLink app that gives me trouble now. Devices have been fantastic otherwise. Just wish the app was reliable.

I figured out the reliability problem for me is related to newer Lan Mode feature. Found the setting to turn it off for each switch and now everything works fine. That’s a shame though. My internet has gone out and left me unable to
Control switches remotely. Be great to have this feature working reliably.


Easy to use works great

The eWeLink app makes setup & configuration of smart devices very easy. I used the app with a Sonoff 4ch Pro. Within 10 minutes out of the box i had the Sonoff 4ch Pro working properly. This time includes installing & registering the eWeLink app, connecting the Sonoff 4ch Pro to wireless, updating the firmware and even adding the skill to Alexa.

The eWeLink app is great, you can change the inching (momentary) settings for each switch, including the duration. There are a lot of other settings for the Sonoff 4ch Pro that can be adjusted through the app.

*Keep in mind, during initial configuration the eWeLink app will connect the smart device to the wireless network that your mobile device is using. After configuration your mobile device will be able to control the smart device through the eWeLink app from any network.

Piece of junk

Literally, the worst app I’ve ever installed and used in my life. The lightbulbs are ALWAYS irresponsible and offline. I have to rest the light 2-3 times every single day. No we to contact eWeLink or Sonoff. I’ve installed all light switches, light bulbs and “smart” plugs from Sonoff, which use this horrible app that never worked properly for one straight week without failing.

I’ve tried everything from resetting the lightbulb, which is a pain in the behind to do so and if you are very lucky, the light bulb would rest. I on the other hand, have tried everything with these light bulbs and they will never connect to this horrible. I also deleted every single smart device from my router and reprogrammed everything. EWeLink and Sonoff are the only light bulbs that are always irresponsive and I was never able to get them to work even when I changed my entire network and password.

Do yourself a favor and buy proper light bulbs and smart devices from somewhere else.

Developer Response ,

Dear user, we understand how you feel. Sorry for the trouble. Please keep your devices close to your router and reduce the connected devices to your router for a better network connection.
