Rules in Eve allow the automatic triggering of scenes in your home. You may set up rules with location and/or value triggers and assign them to a scene you have already created. Example: When you arrive at your home, the lights in the hallway and the entertainment system automatically switch on. Unlike timers, rules can be restricted by time or value conditions. Using conditions allows you to fine-tune your rules. Please see the examples of using conditions below.
Before setting up rules in Eve’s setting “Automation,” you have to have created scenes—for example, a scene called “Entertainment off” that switches off, via Eve Energy connected to an outlet switch, your TV, audio system, Apple TV, and gaming hardware. Another scene could turn lights on or off via Eve Energy or Philips Hue. Another scene could turn your heater, powered by Eve Thermo, on or off, or turn your humidifier, connected with Eve Energy, on or off.
The following examples use location triggers for rules for arriving (“Arriving At”) or leaving (“Leaving”) your home. A simple rule without conditions would be this: Once you leave your home, activate the scene “Entertainment Off” or upon arrival, switch on the humidifier, which is connected via Eve Energy.
You create rules and timers on your iOS device and, unlike scenes, they are not synchronized with your other iOS devices. An Apple TV in your home ensures that timers and rules also work if you’re not in range of the HomeKit-based devices, that is, if you are on the road.
Time conditions, unlike regular timers, are suitable for allowing a rule to trigger a scene only during a certain time period. Time conditions might include prior to or after a specified time or before or after a day event such as sunrise or sunset –for example, a time condition “before 7am” or “after sunset.”
When I get home and it is after sunset, activate the scene “Lights On.”
When I leave the house and it is after 8 p.m., activate the scene “Entertainment Off.”
You can specify multiple time conditions for a rule. In these cases, to have a rule trigger the selected scene, all conditions must be met.
When I get home and it is after 7 p.m. (condition 1) and before 10 p.m. (condition 2), activate the scene “Entertainment On.”
When I leave the house and it is after sunrise (condition 1) and before sunset (condition 2), activate the scene “All Lights Off.”
What does not work: Say, for example, you want to trigger a scene with a rule that uses the day-event time conditions “after sunset” and “before sunrise,” that is, the time of darkness outside. In this case, the two conditions rule out each other since HomeKit uses the 24-hour clock. At 11 p.m., then, although it is after sunset, it is not before sunrise on the same day. In this case, you would have to set two rules with time conditions.
Even more interesting than time conditions are value conditions. The values of the Eve devices in your home are available as conditions. The same applies to other HomeKit-capable devices such as Hue bulbs. All Eve devices support this such conditions. The devices’ values come into action here. You may set fixed values (e.g., a certain temperature using Eve Room) and set greater-than or lower-than values. As opposed to triggers, the value does not have to change. Rather, the value is queried from the device and used for the condition. Here, we’ll use location triggers again for our examples and premade scenes, of course. (Note that selecting “Value Condition” will show you accessory values to use as conditions.)
When I come home and the temperature in the living room (Eve Room) is below 65 degrees Fahrenheit (less than 65), set the target temperature for Eve Thermo in the living room to 70 degrees Fahrenheit.
When I come home and the humidity in the living room (Eve Room) is below 40 percent (less than 40), activate the scene “Humidifier On” (Eve Energy).
You may use more than one value condition in a rule, as in this example:
When I leave the house and the temperature outside (Eve Weather) is warmer than 64 degrees Fahrenheit (greater than 64) and the temperature in the living room (Eve Room) is warmer than 70 degrees Fahrenheit (greater than 70), activate the scene “Heating Off” (Eve Thermo, Mode: Off).
Combining Time and Value Conditions
Besides combining several time conditions or several value conditions in a rule, you can also include both types, as in this last example:
When I leave the house and it is after 10 a.m. and the temperature outside (Eve Weather) is warmer than 64 degrees Fahrenheit (greater than 64) and the temperature in the living room (Eve Room) is warmer than 70 degrees Fahrenheit (greater than 70), activate the scene “Heating Off” (Eve Thermo, Mode: Off).

We hope our examples are helpful as you create your first rules and conditions. Then again, you might already be using rules in your home that you created. If so, we’d really like to hear about them.
