Re: @Andrew Fernie (as: WTF?)
"What good is the "ap" notification going to do for you? What use is it? Is it helpful?"
For normal people, having an 'app' (not an 'ap') is useful because say, oh for example you might want to stop in at a shop and buy a battery for the smoke detector, or at least set a reminder to change it if you have some at home. In the case of a CO detector, it puts you in a position to know there might be a safety hazard at home before you step through the door. Surely a man of your wide experience and amazing knowledge shouldn't need that pointed out.
"My horse's stall needs it's shit removed" isn't exactly handy when I'm a couple hundred miles from home"
That's nice, however unless your horse's horseshit is as prone to setting off smoke alarms as your own horseshit is to setting my horseshit detector, it's not really relevant, as we were talking about 'smart' smoke/CO alarms, not horses.
"nor is "the barn is burning to the ground"."
No fire department to call? Let me guess, only you are qualified to fight fires on your property, because of your tremendous firefighting expertise.
"When I'm home, all of these things are obvious."
And when you're not? Are are now claiming you can be in two places at once? At this point, nothing would surprise me.
