I wrote a SmartThings SmartApp, SmartThings Device Handler and a REST API server to enable the ability to use wireless clients on an Unifi Controller as presence sensors.
If you have a local Unifi Controller running on your local network, then you can use it’s wireless clients as presence sensors. I wrote this because of unreliable presence sensors. Hoping that by detecting if my phone is connected to my Unifi wireless network it will provide quicker / more reliable presence sensing for my automations.
If you would like to use Unifi wireless clients as presence sensors, give this solution a try and let me know what you think.
