I purchased several HS103 smart plugs for my home.  I have been able to set them up and access them through an Android phone.  But, most of the people in my home use iPhones.  The phones won't identify any of the plugs.  It has been tried on an iPhone 16 Pro, 15, and 12 Pro.  I have spent much longer on this than I should have.  I have tried both the 2.4 GHz and 5 GHz bands for the phones and the devices.  All of the devices have the necessary local network permissions and Bluetooth is on.  I don't see how it could work with Android and not iPhone.  They aren't overly useful if no one can use them.  I'm hoping that someone will be able to help me out because if not I'm going to return them and go with another brand.
