In addition to numerous improvements, the latest firmware upgrade for your Eve accessories features value triggers, which you can apply to rules for automation. These value triggers include Temperature, Humidity, Air Quality, and Power, among others.
In iOS 9.3.x, rules with value triggers exist and operate on the iOS device originally used to create them. By contrast, with iOS 10 and an additional Apple TV 4 running tvOS 10 in your home, rules you create on your iPhone synchronize with Apple TV 4, and triggers exist and operate on your local home network. Put simply, once created, scenes will function independently of your iOS device, meaning they will operate even while your iPhone is without a cellular connection, or shut down.
To add a value trigger, use the tab bar to access Scenes > Rules > Add Rule > Next > Add Value Trigger, and see the available value triggers listed under Types.

Value Trigger by Room or by Type
Value Trigger Any for Temperature
Value Trigger Exact with Condition
Rule with Trigger and Condition

Value Trigger: Power (Eve Energy)
The characteristic, Power (On/Off), can be used as a value trigger for rules. Tap Types > Power to view and use your installed Eve Energy accessories. Activate the Eve Energy you want to trigger the rule. Under Trigger Value you’ll find Any and Specific. If you select Any, the value trigger will activate as soon as Eve Energy is turned on or off. If you select Specific, you have the choice between On and Off, and a shift to your chosen value (i.e. On or Off) will trigger its associated scene.

Value Trigger: Contact (Eve Door & Window)
The characteristic, Contact (closed/open), can be used as a value trigger for rules. Tap Types > Contact to view and use your installed Eve Door & Window accessories. Activate the Energy Door & Window you want to trigger the rule. Under Trigger Value you’ll find Any and Specific. If you select Any, the value trigger will activate as soon as Eve Door & Window is closed or opened. If you select Specific, you have the choice between Closed and Open, and a shift to your chosen value will trigger its associated scene.

Value Trigger: Temperature (Eve Room, Eve Weather)
The characteristic, Temperature, is available for Eve Room and Eve Weather, and can be used as a value trigger for rules. Select Types > Temperature, then select and activate the Eve Room or Eve Weather you want to use in a rule with a value trigger. Under Trigger Value you’ll find Any and Specific. If you select Any, the value trigger will activate as soon as the temperature changes (in integer steps, e.g. 20 to 21 degrees) – no matter what the value. You must then set up a Condition that defines the temperature change.
If you choose Specific you have the choice between More Than, Is, and Less Than. When making your choice, you must select a temperature, e.g. 68 degrees. After you tap Next, Eve will automatically create a value trigger with the value, Any, and the required condition e.g. Temperature less than 20 degrees.

Value Trigger: Humidity (Eve Room, Eve Weather)
The characteristic, Humidity, behaves much like the characteristic, Temperature, for Eve Room and Eve Weather. Choose Types > Humidity and activate the installed Eve Weather or Eve Room accessories you want to set up a value trigger for. Once again, under Trigger Value, you’ll find Any and Specific. You’ll also have to choose integer steps; this time, in the form of a percentage. The easiest way to set up a value trigger is to choose Specific, then More Than, Is, or Less Than; and select a value for Humidity, e.g. 40 percent. After you tap next, Eve will automatically create a value trigger with the value Any, and the required condition e.g. Humidity less than 40 percent.

Value Trigger: Air Quality (Eve Room)
In addition to temperature and humidity, Eve Room allows you to use Air Quality as a value trigger for setting up rules. If you choose Types > Air Quality, you’ll see the Eve Room accessories in your home. Activate the Eve Room you want to set up a value trigger for, and select Specific. You’ll see Better Than, Is, and Worse Than; and Eve Room values for air quality (Excellent, Good, Fair, Inferior, and Poor). Select one of these values for your trigger, and tap Next. As is the case with humidity and temperature, Eve will set up a value trigger with the value, Any, and the associated condition in which your target value is defined.

Specific Features and Behavior Value Triggers
Unlike value triggers for Power (on/off), and Contact (closed/open); temperature, humidity, and air quality use value ranges. HomeKit does not allow the use of ranges (selecting a value out of a range) in a trigger. Instead, you must set up a value trigger with the trigger value, Any, and add a condition featuring a value to trigger the scene associated with your rule.
Another specific behavior arises from HomeKit, and it affects the value triggers Greater Than / Less Than associated with Eve Room and Eve Weather. Example: If you set up a trigger to activate when the temperature is Less Than 68 degrees, its associated scene will function when the temperature drops from 68 degrees to 67 degrees. The scene will continue to function as the temperature drops from 66 to 65, and so on. This behavior also applies to humidity and air quality.

Hue Lamps
If you have a Hue system installed in your home, along with Eve accessories, you may use the characteristics Power, Color, Brightness, and Saturation for setting up value triggers. In Eve, Select Types > Power and you’ll find value triggers for your Hue lamps, plus the values for Eve Energy, On and Off. When using Color, Brightness and/or Saturation as a value trigger, you may use Any or Specific. In the latter case, you must define an exact value.

Push Notifications
Eve devices with a firmware upgrade provide HomeKit notifications. For example, an upgraded Eve Weather will notify your iOS device whenever a value like temperature or humidity changes. The rule you set up is checked and, if the value trigger and condition are met, the associated scene is activated.
We’d love to get push notifications, like a message saying, “Eve Door & Window is open” after we’ve left home – but that’s a different story. This is iOS/HomeKit, so Apple has to provide the functionality, and Apple defines the types that are allowed to use push notifications. To see what is available, open iOS “Settings > Notifications > HomeKit” and scroll down. You’ll see “HomeKit Options” with “Security Systems,” “Doors,” “Locks,” and “Windows.” (If you have set up additional homes or are invited to the home of another person, select your home to see the setting).
