1 of 4 HS-110 units stuck on Local-Only mode. Also reports time is not in sync
I have 4 HS-110 smart plugs around my house.
2 of those were unplugged for over a year, since the COVID-19 thing.
I decided to bring them back online today.
I have not done anything with Kasa App for over a year again.
So I decided to update the firmware.
3 of 4 updated fine. 4th one repeatedly says failed to update, please try again later.
The failing plug on the devices screen shows Local Only while other three are displaying the scheduled time underneath them.
I can command the problematic switch from the Kasa app for turning on or off and I am on the same wifi network.
The phone I am using Kasa app on, is sitting next to the HS-110 unit so, WiFi signal strength or coverage is not an issue.
I have unplugged the HS-110 and plugged back in and again to another outlet. No matter what I do, I can not update firmware or let it get out of local only mode.
All other 3 HS-110 units updated to firmware V1.2.6 today, while this problem one is still sittin on 1.2.5 if it is relevant.
I need help.
EDIT: For the record, I did a factory reseton the HS-110 and removed it from my Kasa app and re-added it as a new device. But as soon as it is discovered, Kasa app tells me new firmware apdate is available and whn I click on update, it fails to update. Do I have a dud in my hand ?
