I noticed a new option in eWeLink latest update.
Under Device Settings, the new option is "Vibration Switch" with "Open" and "Close" buttons.
Can you please explain what this setting does/controls?
The "vibration switch" turns on/off the vibration on your phone when the device is switched.
Unfortunately the english translation to "Open" and "Close" is poor and it should be "On" and "Off"
There are quite a few areas where english translation is missing or poor but it does not really affect the ability to operate. Some notifications are not translated which should be fixed.
