Good sensorIgorI like the sensor connected to a DIRIGERA hub. There were two issues though: clock is auto-sync in UTC and I don't see how to change it to use in my time zone. Ios app shows temp in celsius on UI (top of a sensor history screen).4
It would be nice if you gave me an option to reply.JamesI gave this product a bad review because it's basically useless in HomeKit. IKEA responded and said they were sorry the sensor isn't "compatible with my smart systems". It's Apple HomeKit, not Bob's Home Smart Home Stuff. Please don't act like this isn't at one of the top 3 smart home ecosystems. Then you proceeded to tell me I can return it. It's not worth driving 300 miles to the nearest store to return a $30 product. I was so hopefully for these new low cost Matter of Thread devices but they have been very disappointing. The only product so far that I've been happy with is the buttons.1
Awesome Little Sensor - HomeKit Integration Needs WorkBlakeThe build quality on this thing is great. The sensor is high quality, the injection molding feels durable, and the display is very legible. Matter over Thread support is the future and 100% the direction IKEA needed to go. You can’t find a comparable product for this price point, and in that sense IKEA nailed it.
That said, the HomeKit Integrations need some work. None of the sensors are separated out when viewing them in the Apple Home app, and you can’t view the temperature or humidity in the Apple Home app at all. If you look at the sensor in Eve’s iPhone app, it shows all the details separated, but that isn’t a real solution. Hopefully, this will be addressed in software updates (via the Apple Home app), but I can’t fully recommend this for HomeKit Users until IKEA updates their firmware.4
Works perfectly with Home Assistant.DanielThe route I used to add this to HA was to pair it with HomeKit, then display the pairing code and add it to the Matter integration in HA.5
Pretty useless in HomeKitJamesI was assuming that you could get notifications in HomeKit if the air quality fell below a certain level or if the CO2 level went above a certain level.
There are zero options to get notifications of any kind from this sensor.
Also like others, the temperature and humidity don’t show up in HomeKit climate info.
Very disappointing. 1
Functions well but could be designed betterJThis sensor works well- plug it in and shows all your air quality readings. It also detects ambient lighting and dims automatically, which is great. I'm also glad Ikea has been adopting Matter. It connects up easily to my thread border router. The clock synced up instantly once I paired it with matter. The monitor itself also looks very nice, it blends in well in the home.
What I don't like:
- No cable or power adapter included. This is a pretty big nuisance
- Temperatures in Fahrenheit are only report to the nearest degree. I wish it had 1 decimal place.
- I wish it was bigger so it could display multiple values on the screen at once. Like at least temperature/humidity on one screen, and CO2/PM2.5 on the other. I don't like having to pick a singular value to be displayed all the time unless I walk up to it and press the button.3
Clock Is UselessBrianSo the clock has its own local time, which it continually reverts to no matter what I do to manually adjust the time setting. I've got this matter paired for my Apple Home. Main reason to use as a clock in a living room, with the side benefits of the environmental readings it offers. Ugh. Since I'll only be using this paired via Matter I doubt we'll see a firmware fix for this. Ugh. Will return.1
FrustratingMarkMy Alpstuga won't connect to Matter or Home apps. Google searches on various word combinations produce nothing useful to resolve the issues. I cannot find even basic operating instructions either. I only gave 2 stars since I might use it as nice-looking clock or hygrometer.2
Missing temp & humidity in Apple HomeTaylorMost disappointing to me is that the temperature is no where reported in Apple Home. Humidity isn’t either except if you view the accessory details which is difficult to get to. These should be reported under Climate -> Temperature & Humidity sections. Setup wasn’t straight forward until finding info about the buttons from the manual pdf file online. So to not accidentally reset it with one button and how to change to Fahrenheit etc. But continued to be frustrating as setting the time would not take, would immediately reset to bogus time - finally gave up and later noticed it had finally synced the time correctly I guess.3
Died after a weekTedThe sensor wouldn't turn on after a week of normal use. I tried unplugging, resetting, etc. It somehow came back to life after a couple days, but then died again after a day. Thankfully I could return it. It's too bad because it really was a perfect sensor. Hopefully it's a quality blip.1
CO2 reading too high. Need firmware fix.SukCO2 reading in lower range 300 to 500 is relatively accurate but in anything higher range like overnight in bedroom is too high compared to other meter (I have to subtract 600 from its reading to get reasonable level). Please fix this by firmware update. In addition, there's no way to change Temperature unit to Fahrenheit in the Google Home. Otherwise it's solid thread device.2
temperature off by almost 10fEricI want to love it, checks all the boxes for me... But if the temp is off by so much, it's hard to have faith in other sensors being very accurate. The instructions don't seem to have a way to calibrate it.3
Small but mightyJorgeThis is a really tiny little device that works well. I got it for co2 sensing in my bedroom/office. Good thing i did the censor went orange as soon as i connected it, until i turned on the fan. Now i know when to turn on the fan/ open a window. Also i dont have it connected to any hub so if your wondering if you need a hub for it to work. Anyways solid product for the price need one in every room with people in it.5
Great clock that happens to be an air quality monitor ShaneEven though this first is an air quality monitor, it’s a great clock, it can sync time via Matter over thread. Dims its display based on lighting in the room. Its display can even be turned off at night! 5
Matter + ThreadSteveLike all of the new IKEA home automation lineup does, this uses Matter + Thread (and is not very clear about it). If you only have Matter + Wifi this won't work for you. Once you get past that problem and set up a Matter + Thread network (or use the IKEA hub), it's actually quite nice.
This device stylizes itself as a little clock, with CO2, PM2.5, temperature, humidity, and "air quality". It connected to Home Assistant easily and updates its readings regularly. So far my main complaint is that there's no way to set what's being displayed remotely or set the time remotely - you can only turn on/off the display. It's possible that's a failure of the Home Assistant integration, but I'm not sure.
The CO2 readings didn't always match my Aranet sensor, but for the price, I'm not going to be that mad. It seemed within around 100-200 PPM most of the time.5
Works with Apple HomeJoannaA snap to add via iPhone. Here to purchase 2 more.5
Uses Thread & Great InformationMattSo I actually love that it uses Thread since that's a more robust standard (but does require a hub). I love the easy at a glance information and plan to get a few to place around the house.
Great for monitoring CO2 level and general air quality. Now I just need to figure out some cool automations to do with these :).5
High Quality Sensor, Reliable ConnectionTannerWas really pleased to see that this was a routing capable Thread device instead of being Wi-Fi enabled. I wouldn't want to have something so small and simple on my Wi-Fi.
As for the sensor itself, seems to be pretty high quality. The sample rate is extremely frequent (probably because no battery). I'm seeing no noise on any of the sensors. I also love that there is a Matter binding for turning the LED backlight on and off. This makes the device maximally useful, I can place it anywhere without having to worry about the burden of disabling or enabling the screen at any given location.
I joined it to my HomeAssistant without the use of any hub. Good job IKEA! This seems to be one of the best in the market right now.5
Works well with Home AssistantAjPaired easily with Home Assistant and all entities populated for monitoring. USB C powered. Buttons on the bottom are a bit confusing, but some trial and error explained what they do in terms of changing the clock and units on temp.5
Works perfect!KushalWorks perfect! Yes it needs a hub but any thread hub will work. Worked with Home Assistant with no issues. Reads CO2, PM2.5, Temp and Humidity5
