I use these currently four methods to detect my presence:
- Life360 (Ashok's Life360 Presence)
- Hubitat app (Ashok's Pixel Presence)
- Alexa app (turns on a Virtual Presence sensor with switch)
- Google WiFi (through IFTTT, turns on a Virtual Presence sensor with switch)
I had to made a quick run to drop something off at a friend's home, and I was curious to compare how rapidly each method would mark be as being "not present" when I left and "present" when I returned.
Not present: 19:07:20 Present: 19:18:07
Hubitat app on phone:
Not present: 19:07:02 Present: 19:13:14
Alexa app on phone:
Not present: 19:07:01 Present: 19:13:14
Google WiFi (through IFTTT):
Not present: 19:05:02 Present: 19:13:13
The radius for Life360, Hubitat app, and Alexa app is about 0.4 miles. Off course, there's no radius for Google WiFi.
It's not surprising that my phone is out of WiFi range faster than anything else - so Google WiFi picks up my departure quickly.
But I'm surprised it picked up my arrival at about the same time as the Hubitat app and Alexa app. Logically, I should have entered the geofence quite a bit before coming into the Google WiFi range.
Also really shocked that Life360 was about 5 minutes slower than the others in establishing my presence.
