FWIW, other integrations use Wi-Fi to debounce unreliable GPS status. One example is the community Owntracks integration that was created to replace Life360 when it went sideways.
Owntracks can be set up to use designated "home" Wi-Fi network(s) to maintain Present status at a location even if GPS coordinates are exhibiting short-term flaky behavior and the phone GPS thinks it has moved when it really hasn't. TL;DR: Wi-Fi can help w/this stuff in multple ways. 
Nice work here.
