I have several IKEA Vindriktning air quality sensors (measuring PM2.5 but not CO, CO2 or VOC) equipped with an ESP32 with Tasmota on it. The level of soldering

  From the article, it looks like it involves a significant investment in DIY time and parts acquisition. Are you using the custom PCB and 3D-printed LED mounts in the instructions? What are you doing differently?

    I've seen articles about it; my understanding it that at minimum, it only involves a small amount of simple soldering to connect an ESP8266 (or ESP32)-equipped board to the IKEA PCB, which is about the limit of what I can do in my current conditions. It also fits into the original enclosure without damaging it, which is a nice bonus. I keep it on my list as a last-resort option, because of two factors: 1. That's only a particulate sensor, and I'm hoping I can find something more comprehensive - at least with TVOC, but a legitimate CO₂ would be nice too. 2. Unless immediately hacked, it's just a paperweight - I'm not going to bother manually recording the two-bit measurement it displays, and my wife isn't fond of colorful indicator lights illuminating the apartment at night.
