Elgato has been making HomeKit-enabled “Eve” Bluetooth accessories for several years now, and the company now boasts an impressive lineup that includes a range of sensors, switches and smart plugs, and motion detectors.
Eve Button, Elgato’s newest product, is a simple little three-gesture switch that’s designed to control all of your other HomeKit products, activating scenes, turning lights on and off, and more.
The Eve Button has a simple, clean design with a silver aluminum shell and a black plastic front plate with a smooth, circular button outline that doesn’t protrude at all.
It’s using the same design introduced in the Eve Degree, so if you already have an Eve Degree, the Eve Button will complement it nicely.
While there is no visible button protrusion, if you press on the button outline in the middle of the accessory, it will depress and activate the Eve Button’s gestures. Pressing at the sides does not cause the front plate to depress, so the pressing motion is limited to the center, which is a clever design.
The back of the Eve Button is where the battery compartment is located, which can be opened with a coin. The Eve Button uses a CR2032 replaceable watch battery that can be purchased from a local store or Amazon.com for just a couple of dollars.novodasoftware You can check battery level in the Home app.
Elgato included four little rubber feet for the Eve Button so you can set it flat on a surface and it won’t slip around, but curiously, there’s no included adhesive strip or mounting option. The Eve Button is the kind of accessory I’d like to be able to attach to the wall near my light switch, but that’s not an option.
With other switches and buttons, like the Hue Tap, there’s an included mounting solution so it can go on the wall or be used anywhere, so this is a bit of a disappointing oversight with the Eve Button. Portability is, of course, the preferred functionality because not everyone is going to use this as a light switch, but it would be nice if mounting was an option. It’s certainly light enough that I could pick up a 3M Command Strip on my own to stick it to the wall.
In addition to the four little feet, Elgato also included a whole slew of HomeKit stickers you can place on the Eve to remind you which gesture does what, which is a nice addition. Hue Tap and other competing button-like devices don’t have that option, and it can be difficult to remember what’s what, especially when there are multiple family members using the device.
There are three gestures available on the Eve Button, which can be tied to three of your HomeKit scenes: a single press, a double press, and a long press.
All of these gestures are simple to execute, and the Eve Button does a good job telling them apart. I didn’t have much trouble with it mistaking one gesture for another, and it takes just a few seconds (sometimes even less) from when I press the button to when the scene assigned to the button activates. You might think Bluetooth is slow, but it’s not, even when I’m in a different room.
I have noticed once or twice that the Eve Button refuses to respond to a gesture, causing me to repeat it, but it hasn’t happened often in the two weeks I’ve been testing it. For the record, I sometimes have the same issue with other accessories of this type. It’s irritating, but not a dealbreaker.
It can get a little confused if you’re pressing the button to activate different scenes that control the same accessory in rapid succession, but that’s not a normal use case and something I did just for testing.
Scenes are the only thing that can be associated with the Eve Button, but Scenes can incorporate as many HomeKit devices as you’d like. You can, for example, set something like a “Goodnight” scene that locks the doors, turns off the lights, turns down the thermostat, and turns on a night light, depending on which HomeKit products you own.
A “Wake Up” scene could do things like turn on the lights, start the coffee pot, warm up the house, and open the blinds. You can also use simpler scenes if you want the Eve Button to control a single device, like a light. Each gesture can also be tied to multiple scenes, which is handy if you want to keep your scenes separate for voice commands but combine them for the Eve Button.
I have the Eve Button set to turn the bedroom lights on with a single press, off with a double press, and then I have a long press set to activate a scene with my Nanoleaf Aurora for a kind of relaxing lighting scene that incorporates many of my Hue lights.
You’ll note that I am using two of the three button presses for an on/off state, because devices like these don’t naturally have on/off functionality. There is a way around this, though, as HomeKit scenes can be set to “Turn Off” after a set period of time in the Home app. So you could potentially set the Eve Button to turn the lights on in a room like a bathroom, and then set a timer to have them turn off again after 10 minutes without the need to use up a second button slot.
You can also add Conditions to Scenes that are tied to the Eve Button, such as allowing a Scene to be activated by the button only after 6pm or when the temperature is below a certain threshold, but I don’t think these are going to be commonly used with the accessory.
You can, of course, activate scenes without the Eve Button at all through the Home app, another HomeKit app, or through Siri voice commands, but sometimes it’s just easier to press a button. It’s hard to transition entirely away from light switches, especially when there are multiple people in the house, and these kinds of HomeKit buttons and switches are useful replacements, I’ve found.
Setting up the Eve Button, is, of course, as simple as any other HomeKit product and it takes just a few seconds. Open up the box, fire up the Home app or the Eve app, add an accessory, scan the code, assign scenes, and that’s it.
Elgato’s HomeKit products are some of my favorite. When HomeKit was new, Bluetooth HomeKit devices didn’t work well, but with the myriad HomeKit improvements introduced over the years, Bluetooth HomeKit accessories like the Eve Button work flawlessly.
I am happy with all of the Elgato HomeKit devices that I use, and Elgato has one of the best product-based HomeKit apps out there. I often use the Elgato app to tweak my scenes and my non-Elgato HomeKit devices. I’m also a fan of the design of the Eve Button (and the Eve Degree), and I’m glad to see Elgato appears to be adopting it across the HomeKit lineup. It’s a big improvement over previous Eve accessories that were a plain white plastic.
If you’re new to HomeKit, you might think that it’s silly to go to the trouble of automating your smart home devices and then adding in a physical switch, but accessories like the Eve Button are useful and eliminate annoyances that come with not having an immediately accessible physical control for your devices. I’ve had a Hue Tap for quite some time and it’s one of my most used accessories just because it’s sometimes easier to tap a button than it is to ask my phone to do something for me.
Button accessories also come in handy in multi-person households and when you have guests who might need to control devices like lights.
I do wish the Eve Button had a few more gestures available because $50 is quite a bit to pay for just three, but you can tie each one to your most used scenes to get a lot of value it. I also wish Elgato had included a mounting solution, but you can fix that with a cheap adhesive strip if you really want it on the wall.
