Yet Another Vindriktning Modification Tale
IKEA is selling their air quality sensor VINDRIKTNING for some time now and it finally arrived here in Australia. I bought my own device a couple of months ago with the plan to modify and integrate it into Home Assistant. Some clever people have already done all the heavy lifting and there is a thread…

Recently I discovered the luftdaten.info project that provides a simple blueprint for measuring particulate matter, and in this post I am sharing how I built and set up my own device and integrated it into Home Assistant.

Every couple of weeks I have to replenish that drum, otherwise the chlorine concentration in the pool water gets too low, and algae starts growing resulting in green-ish pool water. Needless to say, this…

Water disappears from an outdoor swimming pool over time – naturally through evaporation or through a small leak in a pipe that is hard to detect. To some degree rain helps to balance the pool water level, but sometimes you will have to top up manually. If your pool is constructed like mine, then if…
Smarter Swimming Pool 2: Water Temperature
Since my pool is purely heated by the sun, I thought knowing the current water temperature might help in choosing the right outfit – boardshorts or wetsuit – or choose to better stay out of the pool altogether.
