I have 12ft ceilings and hard-wired smoke detectors that like to go off at the slightest provocation. Needless to say, I've had plenty of opportunities to question why there isn't a mid-range option for a smoke detector with an easy way to get them to STFU. I love the creativity of going via the battery, although I wonder how they get around the back-up battery that most smoke alarms have. I've always thought building an alarm that includes a cheap infrared remote would be a massive leap forward without having to spend a fortune on Nest.
