Getting my Lüften on today, the house started to feel a bit too stuffy and dusty, so time to get all those windows open while the weather isn't too bad.

I've got some modded IKEA air quality sensors around the house, reporting into #HomeAssistant, so it'll be interesting to see what it does for those stats.

For anyone interested, i've got 3 VINDRIKTNING modified with ESP8266s and flashed with ESPHome. The mod itself is three wires attaching to some test points on the board

Quick, simple, and easy to do. IKEA does sell 'smart' versions now but i've not investigated them, also they're a lot more expensive than just the basic one and a ESP...

I have a couple I modded with on, and since I had one in my parts bin, one has a BME688 I put in while I had the opened up.

I wrote it up at unixorn.github.io/post/add-sma but the hardest part was not stripping the screws in the plastic case.

Works great with and the tasmota integration.

I like the display on the vindstryka but I don't need another air sensor. Using them to house and power an ESP32 with is appealing though.

The Plural of SRE is an OutageAdd Smarts to IKEA Vindriktning SensorsWe’re doing a kitchen & bathrooms renovation, and the construction is generating a lot of dust, to the point that I was changing the HVAC filter twice a week. I wanted to see just how much garbage is in the air, so I started looking around for air quality sensors. Naturally I wanted one that I could integrate into my Home Assistant so I could generate notifications if the air was extra filthy.

@unixorn @nikdoof @homeassistant Same. If on the other hand they made a cheap CO2 sensor...

It’d be great if they made a cheap zigbee CO2 sensor so we could embed a running and use the co2 sensor as a case and parasitize its power supply

@unixorn @nikdoof @homeassistant From what I've read the actual CO2 sensors are pretty expensive compared to almost any other.

Good quality NDIR sensors are expensive. There are less expensive sensors that infer CO2 from other measurements, but they tend to be inaccurate.

IKEA would have economies of scale most smarthome manufacturers don't, but yes, the decent sensors are expensive.

I can always hope 😃
