For a home #CO2 monitor, I ended up buying an #IKEA #ALPSTUGA for AU$50.

tl;dr: If you just want to keep an eye on relative CO2 levels in your home, this is the thing to get. It's only accurate to within 100ppm-ish, but that's enough for my use. It also does PM2.5, humidity, temperature, and the time - and the display dims very intelligently at night, making it an excellent bedside clock. Recommended.

Welchem CO2 Sensor glauben wir jetzt?

đŸ«Ž #Ikea #Alpstuga mit 401 ppm
đŸ›ïž #ApolloSensors #MSR2 mit 327 ppm
đŸ”ș #Aranet4 mit 496 ppm

🌋 Mauna Loa Observatory, Hawaii: 429.29 ppm

Kann es sein das 6. Stock, Stadt und ca 3 C Temperatur die Messung verzerren?

Wie kalibriert man am besten?

I'm sick of writing it so my new blog post is ready ​​
It's about setting up the Alpstuga with Home Assistant using GrapheneOS <3

The APLSTUGA, HomeAssistant, and GrapheneOS | Baa Baa Blog

I explore the Ikea Alpstuga air sensor, discuss my smart-home setup, Matter, Thread, Home Assistant, and GrapheneOS. I cover some limitations of these projects and work-arounds I’ve discovered, including Graphene’s inability to use the Android Matter Flow. The Ikea Alpstuga is a low-cost CO2, humidity, air temperature and quality sensor. Supporting the open Matter protocol, and costing £25 it’s extremely competitive for a CO2 sensor alone. It apparently doesn’t directly measure CO2 directly but estimates it based on some other variables with the air, this gives it a low accuracy compared to competing devices. However, for estimating whether you need to open a window, it’s perfect. Check out this amazing write-up by Mica on accuracy results https://mica.lgbt/posts/2026/alpstuga/. I’ve purchased three of these for my home (Alpstugas not Micas). GrapheneOS is an alternative to Android supporting on Pixel phones. Its unparalleled dedication to security and privacy makes it not only the best option for FOSS fans, but also the only realistic option when you compare the feature-sets of alternatives. Home Assistant is an open-source application / operating system for connecting, controlling and organising Smart Home Devices. It might be one of the most successful open-source projects out there, it works incredibly well, has a vast active community, and the backing of paid developers.

Bet... cilvēki nolika blakus ar Aranet, un atĆĄÄ·irÄ«ba brÄ«ĆŸiem pat 600PPM.

Vai kāds ir salīdzinājis Aranet un ALPSTUGA ar kalibrētu iekārtu rādījumiem?

Does seem that the Alpstuga is incapable of measuring CO2 below 400, or maybe that's just atmospheric levels ​​
#alpstuga
Got my ALPSTUGA connected to Home Assistant ​​

It was not easy or simple with the TrueNas, Home Assistant and GrapheneOS combo
​​

#HomeAssistant #alpstuga

Erfolg des Tages, nach Kauf eines #IKEA #DIRIGERA Hub “fĂŒr smarte Produkte”, habe ich es geschafft den IKEA #ALPSTUGA #CO2 Sensor in mein #homeassistant einzubinden.

Versuche mit #SONOFF Dongle-LMG21 oder Dresden Elektronik #ConBee3 und #OpenThread Border Router haben nicht funktioniert.

Thanks everyone for their suggestions, I've ordered three Ikea ALPSTUGA.
I think, not as accurate as some other options, but it's WAYY cheaper and hopefully will be decent.
I
think I can just connect it to HomeAssistant without an additional hub, I think Matter can just work over Wi-Fi? If I'm wrong someone let me know please <3

Dans le tout nouveau catalogue de produits domotiques qu’IKEA est en train de doucement commercialiser, l’ALPSTUGA est un appareil particuliĂšrement intĂ©ressant, car rare dans le domaine, en tout cas Ă  son prix. Cet objet mesure la tempĂ©rature, le t...

Hier ein Vergleich zwischen #ALPSTUGA , #TIMMERFLOTTE und meinem alten Sonoff, stehen direkt nebeneinander.
Deutlich zu sehen die hohe Updatefrequenz beim Alptsuga. Der Timmerflotte ist mit 5min auch recht gut, der Sonoff ist dynamischer (hat auch die kleinste Batterie). Timmerflotte scheint etwas trĂ€ger zu sein bei startken Schwankungen (Fenster auf o.Ă€.). Insgesamt sind die Varianzen im fĂŒr den Zweck ertrĂ€glichen Bereich.
