If this is the wrong place, just let me know and I’ll remove it.
I just picked up a couple of Xiaomi door/window sensors, and I was going to use one for my mailbox. Unfortunately, the metal mailbox is blocking the signal, which was always a concern.
I was wondering if there was any chance I could detach the reed switch from the circuit board and wire it back in? This would allow me to mount the rest of the circuit board outside the mailbox, with wires running inside for the reed sensor. I imagine the only issue would be if the length of the wire introduced enough resistance that it could no longer pick up the voltage on the other end? Also, any idea what the Ground and DI+ are for on the other side of the board?
Hoping someone with some more experience can provide advice.
