Now that I can connect the hubs to my router via wifi I've discovered that you can't just switch the hub that a device is paired with.

You need to first remove the item completely from the Tapo app and then readd from scratch.

It'd be good if you have multiple hubs if you could just switch the hub the device is paired with.

(I have one upstairs at the rear of my house and one downstairs at the front of it)
