Thanks to Ronald Reagan, I only have an intuitive understanding of temperature when it’s expressed in Fahrenheit. Unfortunately, but understandably, the Eve Room environmental monitor defaults to Celsius. (I almost wrote “centigrade” there, which should also tell you something about me.)

Finding how you to change the units from Celsius to Fahrenheit is surpassingly difficult. It’s challenging to Google, and it’s not part of the device’s “Frequently Asked Questions” (WTF?).

Here’s the answer: You have to use the Eve app, which is sort of bullshit, but there you go. As a HomeKit user, I didn’t have the app installed, and I had to download it just to change this one setting. (I only figured this out accidentally, by the way.)

On the whole, I’m happy with the Even Room environmental monitor. The build quality is great. But the battery life is poor. And it doesn’t alert you when the power is getting low, it just silently dies and stops working. Sort of like Reagan.
