Ever since its debut at CES 2018 earlier this year, Eve Button has become a hot topic. And now, thanks to the release of iOS 11.3 and tvOS 11.3, it offers an additional function that essentially doubles your Eve Button controls, giving you the ability to toggle between device states. In other words, one gesture – a single, double, or long press – can now execute two scenes.
Take Eve Energy, for example. Previously, if you wanted to switch it on and off via Eve Button, you had to assign one scene (Power on) to a single-press, and a second (Power off) to a double-press. Now, using conditions, you can simply use a single-press to activate either scene – much like any switch.
Scenes, triggers and conditions
First, create two scenes each for Eve Energy – one for on and one for off. Be sure to use the Eve app to create these scenes and rules as Apple’s Home app does not yet provide the necessary means to do so.
Next, create a new rule in Eve via the tab bar in Scenes > Rules > Add Rule. Select Add Trigger, then Other Value > Types: Button Event > Eve Button: On > Single Press. In a conventional configuration, the Turn off Light scene could be assigned directly to the trigger. Now, instead, choose Add and Next and then Add Value Condition. Here, select the type Power, then the accessory (i.e. Eve Energy), set the condition to On, and tap Add.
After tapping Next, select the scene that turns off the accessory.
If everything works as intended, simply pressing Eve Button will switch off Eve Energy and anything connected to it, but only if it is currently switched on (condition).
Use a second condition
A second single-press rule is necessary to turn on Eve Energy when it is turned off. Like you did when setting up the first rule, create this rule with the trigger Other Value > Types: Button Event > Eve Button: On > Single Press. But now, add the value condition Off and select the scene to turn on Eve Energy upon a single-press of Eve Button.
That’s it. You’re done.
In this way, all three presses of Eve Button can be assigned two rules/scenes each. For example: a single press can turn a connected lamp on and off, a double-press can activate and deactivate an audio system, and a long-press can switch between two light brightness levels.
Mandatory: home hub
Eve Button requires a home hub such as a fourth-generation Apple TV, Apple TV 4K, or the upcoming HomePod. tvOS 11.3 or iOS 11.3 must be running on Apple TV and HomePod (this release allows HomeKit toggle switches and fixes a bug that turned on HomeKit devices when opening the Home app).
