msg Properties

See https://nodered.org/docs/user-guide/messages

Usually, the "value" of a message is stored in its payload field. To make integration with other nodes easy, the payload of a sensor message only contains its values, all additional information is stored in other properties.

If a sensor returns multiple values (e.g. temperature and humidity), msg.payload is an array of these values.

In addition to that, msg.valueTypes is an array of value type specifications {unit: ..., name: ..., type: ...}.

This additional information is used for displaying sensor values on the LCD and when sending datapoints to the OpenDash platform.
