I have installed 9 HS200 Smart Switches over the last week. All have worked fine until yesterday when one of them started showing Local Only in the Kasa app.
I can control the switch from within my network but not when over my cell with wifi off.
I deleted the device and reset the switch multiple times. I connected the switch to a different wireless ap on the same subnet. Nothing I've done fixes the problem.
I have screen shots of the errors and information but don't see a way to post them in this message.
