Has anyone created a Smartthings automation using IKEA ALPSTUGA air quality sensor CO2 or PM2.5 values?

[plannersteve (Steve Wolfe)]

I want to use the CO2 and PM2.5 values on the IKEA ALPSTUGA air quality sensor to create automations to start and stop air purifiers and exhaust fans. I’ve read that while the values are visible in Smartthings, they are not available to use for automations. Is that true? Is there a work around like using Sharp Tools?

[Andreas_Roedl]

They are.

[plannersteve (Steve Wolfe)]

Thank you. I probably used the wrong term. I want to create a “routine” in Smartthings to say if Alpstuga CO2 value is greater than 800, then turn on bathroom exhaust fan switch. Is that possible? And what drivers do I need with this sensor? Thanks.

[Andreas_Roedl]

Yes, of course it’s possible…

… with the standard Matter Sensor driver.

Delete the device in the SmartThings app and add it back again. You don’t have to switch the driver or anything - it works out of the box.

Would be great if you could post some screenshots.

[plannersteve (Steve Wolfe)]

Thank you. I don’t have the devices yet, I was asking before I ordered them. My initial web search showed other sources saying that while you can see some indication of Air Quality, one is not able to see actual CO2 ppm values or trigger automations based on CO2 values.

But from the screenshots I can see you know what you are talking so I’m ordering two.

Thanks.

Which aspects/metrics of the air quality sensor are exposed to Alexa?
Is it possible, for example, to create an Alexa routine so announce ventilation is required in a room, or is it necessary to resort to virtual switches?

Which aspects/metrics of the air quality sensor are exposed to Alexa?

I don’t know - I don’t have Alexa. All I know is that the pm2.5 and tVOC of the IKEA VINDSTYRA (Zigbee, but doesn’t matter) is not exposed to Alexa.

@Andreas_Roedl great work on the driver! Looks like there was some challenging hurdles to overcome there! One thing I’ve noticed in pairing SmartThings with Alexa is that the device reports to Alexa as a Temperature Sensor, and as such shows only the temperature on Alexa. I’m wondering if there’s a way in the driver to have it report to SmartThings as a multi-sensor - so Alexa can be aware of humidity, tvoc, PM2.5 etc? [IMG_9211]

Only temp is exposed in alexa

[Declankh]

Thanks, that’s a bit of a nuisance. I’d have liked to have an Alexa routine to announce ventilation needed without resorting to more virtual switches but I suppose I could still do it with a switch.

[all4dom (Dominick Barile)]

I agree. All these gadgets are smart…BUT not that smart. Happy new year.

As far as I know, Alexa still only triggers routines from contact or motion sensors. About four years ago she proudly learned to tell us the temperature… and then stopped there. No humidity, no curiosity, no ambition. So I wouldn’t hold my breath for her doing anything useful with PM2.5, VOC or CO₂ anytime soon.
Happy New Year 2026
