My brother lives in Alaska, and he just built a home this past summer. No Internet, no phone. Just electricity. He has to fill a 1500 gallon water tank in the town because he's up too high to drill a well, there's no running water.
He's not too confident in his heater, and being away from home when it's -20C for more than a few hours can do serious damage if the heaters not running. Most people would just use the Internet, but he can't. So what do you do?
We scripted around APRS raw packets [1] and APRSDroid [2]. He bought some 1WIRE temperature sensors that are plugged into his OpenWRT WAP. The values are served up by apache, and a $10 smartphone from craigslist reads the values and pipes them [3] through APRSDroid. This then goes via the headphone jack to his radio and it gets digipeated a couple times before it hits the 'net.
Now he can watch his home temperature while he's at work and not get worried. How cool is that?

- nickysielicki 11y agoThe broadcasts stop, so at least he knows and can go check on things. There's no reason he couldn't hook this up to an APU or something though.
