Cabin in Tahoe, about 3 hours from my full time home, so I have interest in automating. It is off utilities network - septic well... Even needed a cell booster to get a cell signal indoors. Some devices I've tried: Sensi thermostat Wink spotter (no longer available) Dahua security cam Lockitron was hopefully going to be used for access, but it didn't work out. I've considered adding a tablet for guests to lookup instructions for the house. I have an "EKM metering" (ekmmetering.com) gas meter that can (at some point) be connected to a pulse counter - they have a device that can tie your electric, water, and gas usage into a graph on the net (and they have an API). Tried a wemo light switch - it sucks. I have an Ambient Weather station that feeds current weather stats to weather underground.
