Here is the deal - I want to place an Aqara P2 sensor in my mailbox so that I can be notified when new mail arrives.

I already have M3, G410, and 2 HomePods as thread routers. And I was impressed that M3 holds the connection with P2 from the 5th floor to the 1st floor in a concrete building, while it loses connection at the ground floor.

I ordered an M100 to see if it will extend the signal, but still unsure where I can place it legally in the building.
