IoT Home Thermostats – NEST and Clevermajig.com

nestClevermajig.com now connects and logs your home thermostat data!

Your NEST thermostat is likelyWiFi connected.  Clevermajig.com can be authorized by interfacing through NEST to read your thermostat data!

By adding a new Thing, you can link your NEST thermostat and Clevermajig.com will record your NEST data such as how much you are heating, what the temperature is, what the humidity is, etc.

Potential use cases:

  • Monitor how many hours your furnace has been on so you know when to order more heating fuel
  • Monitor the rate your home loses heat to learn how well insulated your home is
  • Keep a record of the temperature or humidity in your home

Features being added in the future:

  • Connect to Honeywell thermostats
  • Download your data
  • More advanced alerts
  • Advanced temperature control events triggered on any IoT data

Brewing in situ prototype

The first working test version of the real-time connection for a sensor with in situ application is in progress.  This sensor runs sanitized wiring through the air lock which then goes through a waterproof housing into the liquid.


The sensor is connected over wifi which then transmits updates over an IoT backbone.  Currently, it is logging temperature changes into a Google Spreadsheet.


The graph shows an example log from 26 hours.  Not that the temperature fluctuated within a 2 degree Celsius range over this period.

Next steps include adding additional ambient temperature sensors and also to develop the in situ hydrometer sensor.
