Coeus can accept commands via TCP.  Feedback is provided if subscribed.

Command Format

Commands are sent to objects by GlobalId followed by the Action and then any relevant Properties (Properties are interpreted in the order shown).  They are dot delimited and terminated with a carriage return. 
Format: GlobalId.ActionName[.ActionPropertyValue]\x0D

The Global ID may be found on the UI using the “i” button.  Global Actions use a GlobalId of 0.

Example Recall Scene 1 on Area 51:

+-----+-----------------+----------------------------------+
| ID  | Type            | Name                             |
+-----+-----------------+----------------------------------+
| 51  | Area            | Boardroom A                      |
+-----+-----------------+----------------------------------+

Actions:

+-----------------+-------------------------------+----------------------------------------------------------+--------------------+---------+-----------------+--------------------------------------------------------------------------------+
| Type            | Action                        | Description                                              | Reference Property | Ref Req | Triggers        | Supported Properties                                                           |
+-----------------+-------------------------------+----------------------------------------------------------+--------------------+---------+-----------------+--------------------------------------------------------------------------------+
| Area            | RecallScene                   | Recalls the specified scene on this load                 | SceneId            | False   | Digital, Analog | 'SceneId'Integer)'Scene Number to recall'                                    |
+-----------------+-------------------------------+----------------------------------------------------------+--------------------+---------+-----------------+--------------------------------------------------------------------------------+

TCP Command to send:

51.RecallScene.1\x0D

Subscriptions

Subscriptions may be enabled for each action.  When a subscription is requested the current state will be returned.  Any future changes to the actions state will return the value until the subscription is canceled.   A subscription request does not require parameters and does not execute the action.  "+" is used to subscribe, "-" is used to unsubscribe.  Subscriptions are tracked by connection.  If a connection is lost a re-subscribe should take place on a new connection.

Subscribe:
+[GlobalId].[ActionName]\x0D
+51.RecallScene\x0D

Unsubscribe:
-[GlobalId].[ActionName]\x0D
-51.RecallScene\x0D

Reponse to Subscribe and Change of State Response:
[GlobalId].[ActionName]=[NewValue]\x0D
51.RecallScene=0\x0D

All response values are returned as numbers with 0 being false and 1 being true if the state is not a number.
