Array Property Get

Gets one property for each object in an Source Property and creates a new array, with the values of the properties, which is then written to Target Property. If an object does not have Property to Get then null is used as its value.

Possible errors

If the value of Source Property is not an array of objects, the module will warn and will not send a message to modules connected to it.

Settings

Name	Requirements	Purpose	Default
Source property	String 1-64 in length	The property containing the object to convert	data
Target property	String 1-64 in length	The property to write the array to	data
Property to Get	String 1-64 in length	The property to get from the objects	data

Example

# Settings:
Source Property = data
Target Property = data
Property to Get = temperature

# Incoming messages:
{
  "data": [
    {
        "key": "sensor_1",
        "temperature": 31.1
    },
    {
        "key": "sensor_2",

    },
    {
        "key": "sensor_4",
        "temperature": 34.4
    }
  ]
}

# Outgoing message:

}

Null is used as value for object without Property to Get.
The order of the values are kept from input.
