Beyond irritated at this point and looking for suggestions of something to try.
I have several Kasa plugs of various models. All work great as cloud connected devices. I have 1 HS103 that's currently an extra to me, so decided to make it work local to integrate into Home Assistant, where I'm slowly going to move my 50+ Zigbee and Z-Wave devices. Problem is that as soon as I factory reset it, I can never get it to connect to my WiFi again as a Guest. I CAN get it to connect to my very worthless guest mode WiFi, though. If I log back into my Kasa account, I can easily reconnect to the same 2.4GHz network that's rejected time and time again when logging into the Kasa app as a Guest.
So, why will this plug connect when I'm on my account and not when as a Guest?
