I have two Tapo C200 cameras. Both were easy to set up and have worked perfectly for the last 5 months. They were both unplugged when we remodeled the kitchen. Two weeks later after plugging them back in they will not work. It gets to the pairing and then fails

I have:-

Tried all the resets.

Remove the Tapo router and tried to connect direct to my BT hub.

Deleted the whole Tapo App and reinstalled the two outside cameras sucessfully.....but not the C200's

I have taken them and my tapo router in to my work place and set them up without any problem.

Bought them home and plugged them in again and they dont work.

Nothing has changed with my BT Hub

I really need these on as I have a puppy which I like to monitor when I am out of the house.

What else can I do.....short of buying another camera/router and trying?
