  • A P1 sensor. I have recently entered the rabbit hole of home automation. One of the things I care about, is to be as private as possible, so I went for Home Assistant.

    A P1 sensor is a small thingumabob that you plug into your electricity meter and it measures electricity and natural gas use. It comes with its own webserver and it integrates seamlessly into my HA energy dashboard. I did not have to subscribe to any cloud service and as far as I can tell, it does not phone home.




  • I insulated my own house despite not being particularly skilled (to say the least) and absolutely loathing DIY.

    A bit more context. I live in a house that was built in the early 70s. When I bought it back in 2009, there was hardly any insulation and due to the way it was built it was draughty and cold. A few years ago, I had the walls insulated, which made the major rooms a bit warmer. However, the house was still cold, part of the problem being the crawlspace and concrete floor. Last year, I got all the debris out of my crawlspace and put a thick plastic film on the sandy floor. That had instant effects: not only did the humidity drop (and some occasional musty smells), but we also needed to use less natural gas to heat the house. This year, I finished that project by insulating the bottom of the concrete floor with thick rock wool. That job took me several weeks. First, i had to glue wooden slats to the bottom of the floor and then I had to apply the rock wool.

    My DIY skills are poor. I did this alone. It was a hell of a job which I do not intend to do a second time. However, the rewards, both in terms of comfort and savings are great.
