The location of one of my TPLINK HS110 never able to detect my WiFi. So I can’t switch it on and off.
So I purchased EVE Energy Switch instead as it does not requires Wi-Fi. It is homekit compatible so I guess it is using bluetooth. It receive well.
Receive well in place where Wifi signal not available
The size of the switch is a lot smaller.
Expensive. A lot expensive than HS110.
