Two years of home heating data


A complicated graph.

I have a Tado smart thermostat - part of my smarthome project. As well as letting me set the temperature from my phone, it records environmental data, and provides a handy API for me to retrieve it. This blog post will show you why I've gathered the data, let you download the full dataset, and explain what I learned from it. Why do this? There's a long-standing plan to use waste-heat from a nearby supermarket to provide communal heat to our neighbourhood. A low temperature heat main…

I've an unhealthy amount of smart gadgets at home. Enough so that it's worth running an orientation session when friends come to visit.
