Review: Elgato's New HomeKit-Connected Eve Degree is a Sleek, Palm-Sized Temperature Monitor

by

Elgato recently updated its Eve lineup of HomeKit-connected products with the Eve Degree, a temperature and humidity sensor that joins the existing Eve Weather and the Eve Room.

Priced at $69.99, the Eve Degree feels like an iteration of the cheaper Eve Weather. It monitors temperature, humidity, and atmospheric pressure like the Eve Weather, but it's smaller, better designed, and it includes an LCD display.

Design

Eve Degree is palm-sized and the tiniest of Elgato's temperature sensors, measuring in at 2.1 x 2.1 x 0.6 inches. For comparison's sake, the Eve Weather is a good deal larger at 3.1 x 3.1 x 1.3 inches.

The Eve Degree features a square-shaped anodized aluminum body with a temperature readout that makes it easy to see the room's temperature without needing to check an app. Compared to the white plastic Eve Weather and the Eve Room, it's more stylish and better able to blend in with a range of decors, plus it's lighter so it's easier to mount on a wall if desired.

Eve Degree compared to Eve Weather

Compared to the Eve Degree, the Eve Room and the Eve Weather look bulky, clunky, and cheap. The Eve Degree is sleeker, feels sturdier, and looks like a higher-quality product, but there is a visible logo on the front.

At the back, there's a cutout so it can be hung with a nail, but it's light enough that it would also stay up with an adhesive strip. Aside from the front display, there are no markings on the device. At the back, there's a battery slot that can be opened with a coin to accommodate a CR2450 battery, and a button for turning it on, switching between temperature/humidity readings, and resetting it should the need arise.

Because it uses a replaceable CR2450 battery, the Eve Degree does not need to be charged. According to Elgato, the battery should last for a year and it costs around $5 to replace.

Eve Degree has an IPX3 water resistance rating, which means it can withstand spraying water for up to five minutes. That means it can hold up to a little light rain, but in a downpour, it needs to go indoors.

Sensors

Eve Degree can measure temperatures between 0°F and 130°F with a +/- 0.54°F accuracy range, and between 0 to 100 percent humidity with a +/- three percent accuracy range. That's identical to the older Eve Weather and superior to the Eve Room, which can only measure 32°F to 130°F and 5 to 95 percent humidity.

Its atmospheric pressure operating range is 260 - 1260 mbar/7.7 - 37.2 inHg with an accuracy rating of +/- 1 mbar/0.03 inHg, slightly more accurate than the Eve Weather.

Temperature readings matched what I saw on the Eve Room, Eve Weather, an independent temperature/humidity monitor, and on my thermostat, so the measurements seem accurate. According to Elgato, the Eve Degree has been built to track temperature and humidity with "unrivaled precision."

Connection

Unlike most HomeKit devices, the entire Elgato Eve lineup, Eve Degree included, works over Bluetooth. No WiFi network or hub is required, but to use it away from home, an Apple TV or iPad is necessary.

When HomeKit was new, Bluetooth HomeKit devices were unreliable and were prone to spotty connections, but thanks to improvements introduced over the last two years, that's no longer the case. Eve Degree is reliable and works regardless of where I'm at in my apartment. It also connected fine outside on my patio from inside the house. Be aware, though, that this doesn't have quite the same range as WiFi and could be unreachable at times in some setups depending on house layout.

Setup, App, and HomeKit Integration

Setting up the Eve Degree took less than a minute, which is the case with most HomeKit devices. I opened the Elgato app, chose to add a new device, turned on the Eve Degree, scanned the HomeKit code, and it connected to my HomeKit setup immediately.

The Elgato Eve app is one of the better HomeKit apps on the market. Elgato was one of the first companies to come out with HomeKit connected devices and has had a lot of time to refine its app and figure out what works and what doesn't. The app is simple, straightforward, and easy to use. It's great for Elgato devices, and it plays well with other HomeKit products. When using the app, it takes just a couple of seconds to connect and get a temperature reading.

For the Eve Degree, the main "At a Glance" view displays temperature and humidity, and a 3D Touch on the Eve Degree icon offers more detail, including temperature, humidity, and atmospheric pressure readings over time.

evedegreemeasurements
The Eve app lets you drill further down into the readings, offering up hour, day, week, and month views for each of the metrics measured by the Eve Degree. You can even see specific measurements at a certain time and make comparisons to previous days.

There's also a "Rooms" section in the app that offers up a look at all of the HomeKit accessories in a specific room, while "Types" groups devices by what they do, lumping together temperature monitors, lights, motion, power, and more. Through the "Scenes" section of the app, the Eve Degree gains some of its most useful functionality.

evedegreeroomandtype
A Rule can be created that uses the Eve Degree as a trigger to activate a Scene when a certain condition is met. As an example, a trigger can be set to turn on a HomeKit-connected fan when the temperature hits 75 degrees (as detected by Eve Degree), or it can turn on a humidifier when the humidity in a room dips below a specific threshold. It can activate any kind of scene and combination of HomeKit products, so you can create a range of useful temperature-based automations.

evedegreetriggers
People who use multiple HomeKit devices will may prefer to use Apple's Home app. When set as a favorite device, Eve Degree will display temperature and humidity readings that can be seen on the main Home screen. You can't create the same kind of rules in the Home app, which is somewhat confusing, and hopefully a problem Apple will solve with future iOS updates.

evedegreehome
As far as Siri integration goes, the voice assistant can be asked questions like "What's the temperature in the office?" or "What's the humidity in the office?" Atmospheric pressure isn't a response Siri can give, though, so the app will need to be used for that measurement.

Bottom Line

The Eve Degree is far from cheap at $69.99, especially when a standalone temperature/humidity monitor can be purchased for less than $10, but it has the potential to add valuable functionality to a HomeKit setup.

If you already have a HomeKit-enabled thermostat, you likely won't need a device like the Eve Degree, but if you don't have a HomeKit thermostat, it offers a handy way to keep an eye on the temperature in a room both at the moment and over time, plus it can be used as a trigger for connected devices like humidifiers or fans.

The Eve Degree is also potentially useful if you have an area that needs separate temperature monitoring, like a wine cellar, or if there's an area in the house out of range of the thermostat. Eve Degree can go outside, but since it only offers an IPX3 water resistance rating, it'll need to be kept out of direct rain and moisture.

evedegreeandeveapp
Elgato's Eve Degree is functionally identical to the cheaper Eve Weather with the exception of the display, the new design, and better atmospheric pressure accuracy, so if a display isn't needed, the Eve Weather is $20 less expensive at $49.99 and perhaps the better buy for outdoor use, where most monitoring will be done from inside the house.

Indoors, the Eve Degree doesn't have the air quality sensor in the $79.99 Eve Room, but it features a sleeker, simpler design, it doesn't require an app to get a quick glance at the temperature, and it works in a wider range of temperatures, which makes it arguably more useful.

As someone who has been using the Eve Weather and the Eve Room continuously for almost two years, I am impressed with the new design and prefer the Eve Degree to either of the older sensor solutions. Those who already own an Eve Weather or an Eve Room probably shouldn't upgrade due to the similarities between the devices, but for those new to HomeKit-connected temperature monitors, this is the one to get.

How to Buy

Eve Degree can be purchased from the Elgato website for $69.99.

Note: Elgato provided MacRumors with an Eve Degree for the purpose of this review. No other compensation was received.

Impressive that they're getting an entire year out of a CR2450, I guess that's the benefit of BLE. Any indication how often they're taking and transmitting readings (about once a minute is typical for most 433MHz remote temp/RH sensors, which generally run 6-12 months on 2x AAA's).

I find it interesting their sensor goes to 260 mbar, that's almost unbelievably low, I rarely see it below 1000 (in the last 6 months 996 to 1030 mbar). The pressure in the eye of a hurricane rarely gets as low as 900 mbar. 260 is substantially below the pressure at the top of Mt. Everest (about 300 mbar).

Two comments on the article: 1) sticking the sensor up with adhesive (vs. hanging it on a screw or nail head) will make battery changes difficult; and, 2) "air pressure" is for tires, "atmospheric pressure"* is for weather.

*: (The judges would also have accepted "barometric pressure")

In the post you mention being able to turn on HomeKit enabled fans ... which fans (or conversion kits) are out there? I've only found the Hunter fans that are fully HomeKit Enabled. Or are you speaking more of turning on a light switch that controls a fan? Thanks!

I also only know of the Hunter fans. I was thinking more fans/humidifiers plugged into one of the HomeKit-enabled smart plugs.

Very fugly looking.

So appearance trumps functionality? Elgato obviously was going for a minimalistic design that has mobility and portability over it's over appearance. I don't think It should even be a consideration, considering how small it is and it's intent is to be placed in the rooms were you don't have a physical thermostat and or using the iPhone application. Seems you missed this point completely.

I have a couple of questions and appreciate if you could answer them:

1. I wonder if this device stores the logs locally, like the temp history, without the need to be connected all the time? If so, how far of history could it handle? One day, a week, a month?

2. Could the graphs be exported somehow?

It stores data. If it's like the Eve Room and the Eve Weather (and it seems to be), it can store about two weeks of data before needing to be connected to the iPhone to download that data. So it's ideal to connect every week or so to make sure you're getting all the readings.

Yes, data can be exported. The visual graphics can't, but the raw data the app uses to create them can be exported as an Excel file that can be opened in compatible apps.
