Garage sensor. Uses distance sensors to detect door open/closed and car present /absent. Has buttons to open/close the doors, a 3v garage door remote. Also has a motion sensor, temp/humidity sensor and a photo resistor to understand outside ambient brightness.

Looking at building some fridge/freezer temperature and water leak sensors.

If you can pick it up in person in Markham, it’s even cheaper. Bought a bunch of UPSes across a couple dozen years now, and replaced the batteries on many of them. Best prices I’ve found.

Agree on the creepy side, though there’s other possibilities besides facial recognition, namely:

• They buy data from a data broker. Said data broker bought (or got) location data from any number of apps you have installed on your phone that monitor your location data.
• They associated your phone’s Wifi MAC (even if you don’t connect to their Wifi) or a bluetooth MAC (of bluetooth headphones, watch, or other device) to you previously, then saw it again

Solid File Explorer, bought it forever ago, and it hasn’t let me down yet.
