Winter is coming, and the Northeastern United States where I live can get cold! And the houses are often old and drafty. So I built a wireless sensor system tied to a Nest thermostat to keep me cozy, wherever I am in the house, instead of keeping my thermostat cozy, bolted to its wall.

I did this with Texas Instruments’ Sensortags, a Beaglebone Black, DeviceHive for device registration and management, and a Nest thermostat.

This one was coded up using Python to speak Bluetooth LE to the Sensortags, and JavaScript on Node.js to do the device registration and telemetry messaging.

Yeah, they call it Bluetooth Smart now, but I don’t like that name! LE for me. 😉

DeviceHive managed the device registration for Sensortags, to make it easy to add new tags and wrangle them, and the wot.io data service exchange piped the messaging to scriptr for some transform logic in a convenient cloud service. bip.io did visualization and Nest control, and Circonus handled data logging and analytics.

And the code is on GitHub!
