I recently received an Eve Room HomeKit Air Quality monitor. But when I plugged it in, nothing happened. I let it charge overnight, and it remained stuck on the charging screen. I reset it with a paperclip multiple times. Tried multiple chargers. Tried a different micro-USB cable. All to no effect. The battery either seemed completely discharged upon arrival, or something was broken inside the unit.
That’s when I emailed Eve Support. They suggested resetting it again and waiting a few hours. I did, to no avail. After I sent them a photo of the non-working unit, they agreed to a quick, free replacement.
And the replacement worked great!
My experience with Volker and Sarah at Eve Support couldn’t have been better. Polite, prompt, professional, and a free replacement. I liked their service so much that I went out and bought a second Eve Room for the lower level of my house. I’m also planning to get one as a gift for a family member.
- Air quality monitoring via Sensiron metal-oxide based VOC sensor
- History graphs of your data (see below) – including exporting history to spreadsheets
- HomeKit support – You can ask Siri to tell you the temperature/humidity/air quality in any given room
- Automation – In the Home app, you can have an air purifier come on automatically when air quality drops
- More automation – In the Eve app, you can add additional automations based on temperature and humidity. For example, when temp/humidity get above 80F (26.6C), turn on air conditioner.
What are some downsides?
- Bluetooth-based, which means it takes slightly longer (~1 second) than WiFi-based HomeKit products to display status in the Home app.
- If you want to access Eve from outside your house, you need a HomeKit hub, such as an Apple TV, HomePod, or iPad. (In my experience, the Apple TV is the most reliable of the three.)
- Expensive – $70 more than the bigger AcuRite monitor (though it’s tough to find an air quality monitor with a display for less than $70).
- Not magnetized like the AcuRite – so you can’t stick it to your refrigerator without adding a magnet.
Charging is easy. It takes less than 2 hours and only needs to be done once every couple months. You can also use it with the charger plugged in, though it’s possible this will reduce the battery lifespan a bit. With the AcuRite, you need to replace the 2x AAA batteries every other year. (Though my first AcuRite started reporting obviously incorrect temperatures after a few years – I just bought another one since it was so cheap.)
Are the air quality measurements any good? The only thing I have to compare it to are the measurements from my Withings scale downstairs. The Withings reacts pretty fast to cooking in the kitchen. The Eve Room seems to be a bit more … optimistic on air quality, even when the air seems a bit stale. (a quick blast of the air conditioner clears this up though) It doesn’t care much about soiled diapers, but it does react when people are in the room breathing out carbon dioxide for half an hour or so.
Overall, fun little gadget, and I’m looking forward to setting up automations with it!
