Use Entities

Entity and Entities selection

To select what entity you want to perform actions on use the Entity() or Entities() starting point. Some service calls are built-in to the Entity selections, like turn_on / turn_off.

Simple selection

Example 1: Selects one entity to perform action on

Entity("light.light1").TurnOn();

If you want to add attributes to the call service just do:

Entity("light.light1").TurnOn(new {brightness = 100});

it is important that you use the lower case names of attributes when adding them in anonymous types.

This selects the light.light1 to perform the TurnOn service calls on.

Example 2: Selects multiple entities to perform action on Here we have several options to turn on both light1 and light2.

Entity("light.light1", "light.light2").TurnOn();

This one takes a IEnumerable<string> as input to selects multiple lights

Entities(new string[]{"light.light1", "light.light2"}).TurnOn();

Example 3: Selects multiple entities to perform action on using lambda

You can also use lambda expressions to select entities like select all lights that start name with light.kitchen_. Now it gets really interesting to use advanced selections with little code using LINQ.

Entities(n => n.EntityId.StartsWith("light.kitchen_")).TurnOn();

or select on attributes like example below.

Entities(n => n.Attributes.brightness > 100).TurnOff();

Using Areas

Turn on all lights in the kitchen area:

Entities(n => n.Area == "kitchen" && n.EntityId.StartsWith("light.")).TurnOn();

Special entities

There are no special entities implmented in V2 yet. To use media player features as an example you will have to use CallService.
