Great Addition to my Smart homeTomI love these, and have 4 of them running in my smart home. They connect perfectly with Google Home through Matter over Thread and expose all the information I need to keep my family healthy!! The price is perfect as well
Excellent -- once connectedAndrewIt took many tries to get it connected, but I'm really happy with it now that it's set up. This is an awesome little device. I have several of them around the house.
Capable for the price, but some flawsJoshuaFor the price, this is a very capable device. The CO2 readings are imprecise, but are reasonably accurate and useful for the basic purpose of knowing whether to ventilate the room. Competing products with more precise sensors are much more expensive.
The biggest problem is that temperature unit and 12 vs 24 hour time selection do not persist when unplugging the device. The device also offers no way for a Matter hub to read or update these settings, even though the Matter standard does offer a way to do so. Hopefully Ikea will fix this in a firmware update.
Will not Connect to DIRIGERAMartinHub firmware up to date, dozens of attempts. Matter devices get stuck at "checking connectivity to Thread network.
Half-BakedMaxThe alpstuga multi-sensor has some nice features, but there are several design flaws which make it a pain to use. It seems to report temperatures and CO2 concentrations which differ wildly from other sensors, so I'm not sure how reliable the sensors in the alpstuga are. Even worse, when the device loses power, it does not retain any settings. There are some features which should be exposed to smart home controllers but aren't, such as the LED brightness and the ability to calibrate temperature readings.
Works With Home Assistant - No Temp CalibrationAnonymousConnected to my Home Assistant and updated to the latest firmware. The temperature sensor reads 4 F high and no way to calibrate. The device displays real time however time setting is lost when you loose power and it is not updated when connected to a matter network. Poor design includes: device settings do not persist with a power failure, when connected to a matter network the real time is not synchronized and unable to calibrate the temperature sensor.
Great deviceAndrewLike all of the new IKEA Matter over Thread accessories, it was tricky to get this connected. But now that it is, it’s a great device with lots of functionality at a great price.
Works well when integrated with Home AssistantPaulI bought 2 of these, one for each floor, They are sensitive.
I integrated them with Home Assistant and can cycle my HVAC system fan when PM2.5 levels are high. My HVAC fan uses a hepa 13 carbon backed filter that removes particulate matter.
It integrated with thread easily and directly without ikea's app. The also did firmware upgrades from Home Assistant
Since I'm using it with automation, I don't need it to display anything. I can use programming to turn the display off, but it persists to turn it back on after a power failure. I don't need a clock (that's likely on the wrong time) or numbers that guests don't understand what they mean. "It says 580, is that good, what does that mean?". I wish it simple remembered its last state, including off
OfflineWendyI really like the sensor but it keeps going offline for no reason and forces me to unplug and set up again.
Eye-opening data on indoor air qualityJavenI bought 2. Installed one in the bedroom and one in the kitchen. I couldn't believe how high the CO2 got in bedroom with the door closed, which may have contributed to poor sleep quality. When cooking in the kitchen, even using the range fan, PM2.5 gets into unsafe levels and stays high for several hours. I can't believe I was living with unhealthy indoor air quality all this time.
Feature request #1: add a mode to cycle the LED display between all sensors at a reasonable time interval (15 seconds?). I'd rather glance at the display while cooking than dig around on my phone for the smart home dashboard.
Feature request #2: when PM2.5 or CO2 air quality is unhealthy but isn't currently shown on the LED display, there's no indication on the display that air quality is poor. Please do something to alert the user about poor air quality on the display, like flash the orange dot or toggle the display between the active display and the unhealthy measurements.
Promising Start, eventual failChipI like the display, and the number of things it will monitor and for a reasonable price. However, after a few days the CO2 monitor began to lose it, climbing steadily past 1000 ppm even in outside air. Disappointing.
A good start, but needs updatesAdamI had no trouble adding Alpstuga to Apple Home and my existing thread network. The firmware update went through smoothly, which is a good sign.
The main issues I have are:
* Temperature does not show in Apple Home. Humidity, CO2, and PM2.5 all do, but not temperature.
* Changing temperature unit from C to F does not persist, and it resets back to C.
* Dimming is nice, but I'd like a way to turn off the display altogether (or ideally, have it turn on briefly when the top button is pressed). Right now I wouldn't want to have it in a bedroom at all.
* Software updates need a changelog. We need a set URL where we can see firmware version releases with what changed. Otherwise we're stuck guessing whether our issues have been addressed.
Great CO2 MonitorKirillThe CO2 sensor is quite accurate and serves as a reminder for me when I need to open the windows and ventilate the room.
I’m Liking This Product!RonaldALPSTUGA Air Quality Sensor
So far I’m liking the product:
IKEA thanks for making Smart Homes affordable,
Temp
CO2
PM2.5
Humidity
4 programable functions in one affordable device.
Mattter over Tread network to reduce accessory signal congestion.
Brilliant!
Here’sthe issue I had:
Unable to reset Sensor to factory reset CO2 continues to very High 1200-1443 ppm.
Resulting in poor air quality
Sensor is on current firmware update.
Followed instructions to reset base line CO2 outdoors, at 400 ppm PM2.5 at 0 ppm reporting good air quality.
Reset, removed powered down from 2hrs. No change with CO2 status.
Will return unit for exchange.
Ordering More and other products:
Ordered second sensor appears to be working.
Will order a third and possibly 3 more + other accessories.
What I would like to see enables:
Not just Excellent, Good, Moderate, Inferior, Poor
Also the ppm data displayed.
Also *temperature in smart home app ( Apple Home ect)
Works fine for meDelmarGreat product to identify how healthy your air is in your home. Matter connection works fine for me through Google Hub no issues.
Easy to use and improve your air quality KaseyEasy to use out of the box. Accurate readings and easy to read measurements are something you can’t get from Amazon or any other store.
Great, but a frustrating lack of memoryVictor ManuelThe Good:
The sensor is very accurate. Compared to more expensive air quality monitors, the CO2 and PM2.5 readings are consistent and fast. The design is clean, and the display is very easy to read.
The Downside:
The biggest drawback of this device is that it does not have internal memory or a backup battery for its settings. Every time you disconnect it from the power to move it to another room, or if there is a simple power flicker, the sensor loses all its configurations. You have to manually set up the time and the format (12h/24h) all over again because it resets to factory defaults. It is disappointing that a "smart" device in 2026 cannot save simple user preferences or keep the clock running for a few minutes without power.
Verdict:
If you plan to leave it plugged into one spot forever, it’s fine. But if you want to move it around the house, be prepared to re-configure it every single time you unplug it.
Questionable measurementsAaronNo problems setting up and connecting to Apple home but something very off with readings. Hopefully can be fixed via firmware but CO2 frequently goes up very high even with no one in the room to 1100+. Airthings sensor moved right next to it reads around 590. Also not sure if PM2.5 is working since 0 since purchased. Firmware is 1.0.15
If you’re having trouble pairing with Home Assistant, read thisJDisappointed to see that the temperature and humidity do not show in the Apple home app, but if you’re like me and have Home Assistant, make sure both your hub (apple tv in my case) and home assistant are connected via Ethernet. I tried literally everything else until it finally hit me to try that and it worked instantly once I did.
I split my Wi-Fi band between two and 5 GHz, manually routed from Home Assistant to my hub, disabled ipv4, disabled security settings, watched the logs while pairing, nothing worked. I was about to create VLANS to get it to work lol
Now that I connected both via Ethernet it’s rock solid and logging everything for a week with no issues. Don’t give up, yall! It’s a great product with home assistant.
Not compatible with Apple as promisedPeoThe specs say that this works with Apple HomeKit but both Temperature and Humidity does not show up in Apple home so that is unfortunately false advertisement from IKEA if they can not fix this with a software upgrade sooner than later.
