How to make a trigger to connect a device to home WiFi?

Question

Programming

Good afternoon.

There was a need to track the connection of my smartphone to my home WiFi network and take some action at that moment.
To simplify a lot, then turn on %device_name% when I come home.

Probably you can scan the network constantly and watch the connected devices at the poppy address. Or by IP, I can set a permanent IP to my smart in the router. Or else how?

UPD
Ideally, solve the problem at the level of the router (ROOter firmware), or on the edge of the software in the computer, which practically does not turn off.

Answer 1

The application on the phone will monitor the Wifi connection event with the name xxx and signal the device to turn on, as an option

Answer 2

Finish this script for yourself
