Magnetic sensor on the garage door is probably my favorite “automation” too. Notifies my phone, and I can close it remotely. Other favorites are: - magnetic sensor on basement freezer cabinet, has saved my bacon, literally. - magnetic sensor on roof windows (good old fashion drying attic) that notifies me if it’s about to rain and windows are open. - water leak sensors on everything that’s hooked up to water pipes.
