I’m using the Home Assistant Android app on my mobile phone. The app is reporting my mobile’s wifi connection name to HA when I’m at home and connected to my wifi (which I am when I’m at home :p). When I’m not connected to my wifi, the app reports “not connected” (or similar).
I would like to use this as my presence detection, but I can’t figure out how - at all. When I search, I only find really contrived solutions like using MQTT, or some Bayesian detector, or other strange stuff, but surely it can’t be that hard? In my mind I should just have to (perhaps) create a new binary_sensor or something and use that?
(My motivation is that the “asuswrt” platform device tracker I have been using doesn’t work any more since I’ve been forced to start using a wifi extender, which is an older Asus thingy, which does not use asuswrt, and every time my phone jumps to the extender I’m “not_home”. The Android app “solution” that I’m thinking of does not have this problem.)
