After I gained root access to my vacuum cleaner robot, a new world of opportunities emerges. This is the great aspect of owning your own home devices. And it is geometric. After you add a new liberated device to your home mesh, you can start thinking on all the combinations among your other devices, even […]
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 […]
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 […]

Luckily, handling the screen brightness of my ANAVI Thermometer was easier and more straightforward than I imagined The first step was getting a light […]
I am pretty happy with my University education. I studied Telecommunications Engineering in Spain, which is a mix of Computer Science, Electrical Engineering and Telecommunication Systems. I think it gave me a solid base for a broad range of topics, from the signals inside a circuit to software engineering principles. However, something I have missed […]
After setting up the mighty open source and open hardware Hestia PI in the living room, an extra thermometer in the bedroom was the next step. Hestia PI‘s does its job amazingly well during the day. But when the night comes, we don’t care about the temperature in the living room, but in the bedroom. […]
