Is it possible to discover signal strength between two devices that are connected to the same network?
Devices
A. Cell Phone WiFi
B. WiFi enabled device
C. Wireless Router
Both A & B are connected to C on the same network. I would like to be able to discover the relative signal strength between A and B.
The goal is to enable B detect when A appears to perform an action like turn on a light switch or a coffeemaker.
My current research shows this is not possible unless I add a separate WiFi / detector to B.
