I have 2 HS103 smart plugs that have been connected to my 2.4 GHz network but have dropped out for reasons unknown to me. I did not remove them. I don't think there has been a power glitch. They show up with the names I gave them in my iPhone Kasa app under devices but their info is dimmed.
I have unplugged the one I'm working with first, plugged it back in, held the button until I got blue/amber blinking lights indicating - I think - that it is ready to pair with the network. I go into the iPhone app and cannot find a reconnect procedure nor a delete procedure for these devices (unless, of course, I missed something in the menu sequence). So, I tried adding it as a new device and got through to the screen showing that it was attempting to connect to the plug. The iphone was less than 2 feet away from the router and the plug. After it's time out period, I get the message that it was unable to connect. Retrying got the same results multiple times.
Can anyone suggest another approach if this one is wrong, as it obviously must be because it doesn't work.
