During the winter season, we spend a lot of money heating our homes. Many heating systems are controlled by a basic thermostat installed in a random part of the home. It’s great to know whether the heating came on once, twice, or three times during the day. If the thermostat has been played with, it could have been on for longer than you require.
I have been monitoring our heating system for several years and this year I decided to improve the wiring. Instead of recycling scraps of wire, I have splashed out on some pretty ribbon cable from DigiKey. I have recently written about the sensors and software that I use. The MicroChip MCP9808 temperature sensor mounted on an AdaFruit breakout board is an excellent choice for the Raspberry Pi.
