Presence Detection

Unifi is this Ubiquiti thing where you run a Unifi server (for example on Bellman on port 8443) and it watches all the supported WiFi APs on your LAN and lets you manage all of them from one place. In my case it's just one AP right now. I live in a small house, it's all I need.

I can run python scripts to pull data from the UniFi server, see

This is pure coolness.

sudo pip install unifi
./unifi-ls-clients -c bellman -u readonlyuser -p YOURPASSWORDHERE -v v5 -s default

Better even is turning on logging and watching daemon.log

I can see when a device comes into my network even before it's finished its key handshake and gotten an IP address.

Flask project

I started a flask project and it's in Projects/presence on Bellman. I should get back to it.
