My current favorite ones: - My GF is a bit forgetful and sometimes leaves her purse behind when leaving somewhere. I had an automation setup with an ibeacon in her purse and owntracks on her phone to detect when the purse is far away from her, and send me and her a notification

- i built a bed occupancy sensor so hass knows if we're in bed or not, and disables automations that would otherwise be annoying (mainly the motion-detected lights in the bedroom)

- i come home and say "hey snips, i'm home" which turns on the tv and sets kodi to a plugin that i tend to use.

- i have a snips.ai command (hey snips, let's party) which turns on my lifx bulbs and makes them change colors

- also whenever Eric Prydz comes on my living room kodi, those party lights come on

- i have an announcement go out over snips.ai tts when my 3d print starts (so i can go ensure the first few layers are good) and when the 3d print is done. I also have snips commands to tell me how much time is left on my 3d print job, and if the temperature of the nozzle spikes too high.
