Improved humidity-sensitive ventilation

A few weeks ago, we showed you how to monitor the operation of humidity-sensitive ventilation (type B) with Home Assistant. We left off with the observation that, in some cases, the mechanical humidity-sensitive setting is not ideal. So let's take a look at how a little home automation, used wisely, can improve the system's energy performance.

This week, we're going to do a simple DIY project that will be of interest to anyone involved in 3D printing. We're going to make a box for storing filaments while monitoring humidity.

In addition to reading and writing tags, the Yocto-RFID-15693 module API allows you to program a callback that is called every time a tag enters or leaves the antenna field. And these callbacks are time-stamped. It's only a short step from there to using this feature to build a stop-watch application, a step we didn't hesitate to take.

Humidity-sensitive ventilation and Home Assistant

When insulating a house as part of an energy-efficiency renovation, it's essential to provide ventilation to evacuate any moisture that might accumulate inside. Since it's generally not possible to install a double-flow ventilation system after the fact, the recommended method is to use humidity-sensitive ventilation, which selectively ventilates the rooms that need it most. But does it really work? Let's find out with Yoctopuce modules and the Home Assistant home automation platform.

When we introduced version 2.0 of the command line library, we modified our compilation scripts and realized that we had never explained how to compile the command line library.
