eWeLink could not detect new Sonoff switch
Spent a few hours troubleshoot the eWeLink could not add Sonoff switch issue.
- Tried to move the switch near to WiFi router
- Separate bands in router
- Connect to different router
- Change phone, between iPhone and Android phone
After a few hours, still could not detect Sonoff switch.
In the evening, the suddenly can detect, but could not download device info, got error 401. Then I think it was caused by me after reset password, then used the phone which performed password reset to try again. Finally the device was added successfully.
Then tried at night again, everything ok.
Possible cause
I think it was caused by eWeLink website issue, which could not register new device. And once issue happened, need to reset the device to let the eWeLink App detects again, and I didn't notice the message as well.
