Sets a property based on the provided template.

Inputs

$message struct
A $message object containing information to populate the template.

Note: When not using Mustache, select Plain text in Format to save ressources.

Outputs

Setting Output as to Plain text always outputs a String. Setting it to Parsed JSON parses the template and converts it according to the JSON rules (i. e. 20 is parsed to an Integer, 20.1 to a Float, "My text" to a String, [0, 2, 3] to an Array and so on).

$message struct
a $message with a property set by populating the configured template with properties from the incoming $message.

Details

By default this uses the mustache format, but this can be switched off if required.

For example, when a template of:

Hello {{name}}. Today is {{date}}

receives a message containing:

{
  name: "Fred",
  date: "Monday"
  payload: ...
}

The resulting property will be:

Hello Fred. Today is Monday

It is possible to use a property from the flow context or global context. Just use {{flow.name}} or {{global.name}}.

You can also access environment variables using {{env.name}}

Furthermore you can access device variables using {{variable.peerId_channel_variableName}} (e. g. {{variable.5_1_STATE}}).

Note: By default, mustache will escape any HTML entities in the values it substitutes. To prevent this, use {{{triple}}} braces.
