Feature Request:Monitor WiFi signal strength for Tapo cameras

[steviebug]

Is your feature request related to a problem? Please describe.
I need to investigate WiFi signal strength related to my Tapo cameras. I suspect one of them is too far from the AP.

Describe the solution you'd like
I see from Tapo app that signal strenght is visible and can be visually checked. I would like to have this information stored by HA, so that I could check a graph to undestand if during the day the WiFi signal strenght decreases too much.

Describe alternatives you've considered
I have tried monitoring from OpenWrt router, but HA integration does not contain a sensor with signal strength for connected devices.
