Kasa smart plug is suddenly offline to SmartHub & smartthings app cannot reconnect
Two days ago this outlet was linked & online on my Smarthub, and operated by Google Nest voice & a daily routine. Yesterday the lights on this strip failed to turn on, and showed as offline in the Smartthings app.
The plug and lights are fine in the Kasa app, operable.
I removed the devices from my Smarthings app, and unlinked TPLink/Kasa.
Now I cannot relink my account.
In the Smartthings app I see that I can add a partner device TPLink/Kasa, but if I choose this and login with my TPLink account, I have to choose scan a qr code or scan nearby.
Scan nearby does not find anything, as the device is not in pairing mode. I expected this to be picked up from the TPLink account information. But apparently this fails.
If I try in Smartthings to link my account, I get put in a cycle: "you can add ... existing devices ... by linking your account" so I login at the next screen, but after several seconds I am back at the same message: an endless cycle of login as if it never happened. I am using the TPLink account I use in my Kasa app and online at tplink.
The outlet is up in a loft, and my memory is it was a hassle to pair originally so I hesitate to start over.
Are there any alternatives?
