When I started this IoT journey, my goal was using always free open source hardware and software. At least, as much as I could, given the available possibilities. The next stage in the journey was the vacuum cleaner There is clearly a challenge in this stage: would I find free/open source hardware in the vacuum […]

Visualizing temperatures and heating cycles

During these last days, the weather went crazy in Madrid. A great snowstorm was followed by a great freeze. It was hard for our heater to catch up. But also, a perfect scenario for learning more about what is going on with temperatures inside and outside the house! Since the beginning, when I started with […]

Debugging in Kweb

I have been recently hacking on HestiaPi‘s interface, so I could add the measures from ANAVI Thermometer to HestiaPi‘s interface.

My thermostat, with root access

HestiaPi looks awesome. An open software and open hardware project, Raspberry Pi based, customizable LCD touch screen, it is all you can ask as a basis for your home IoT infrastructure.
