Literals are defined by a name (optional) and a value. The value can be derived from an entry in the Formula editor.
The following shows an example object having four Literals.
{"lat": 40.12,"lon": -96.66,"timezone": "America/Chicago","timezone_offset": -18000,}
Literals cannot have child properties.
Literals are created in the Mapping dashboard by entering a name in the New Property field, selecting Literal and clicking Create.
A value is then entered in the Formula editor.
Alternately, a mapping from an connected unit's attribute can also provide a value using references.
