Spotter ($50) is a multi-purpose sensor that measure the temperature, humidity, light, sound, and motion in your home, letting you connect, control and monitor just about everything. Want your lights to automatically turn on when someone knocks on your door? Sure. Want an alert when your wine cellar is too warm? Wait. You have a wine cellar!? Wow. OK. Huh. Anyways, yes, as you might imagine, Spotter works with your smartphone, so ya know, you’ll need to pry yourself away from your 1978 Montrachet for a moment. Sorry, I just can’t let this wine cellar thing go.
