Helps create node-red omf messages for OCS or connector relay

npm install node-red-contrib-osisoft-omf

This is a collection of nodes to use in Node-RED to help generate an OMF message. Node-RED is open-source, and is part of the [JS Foundation] ( and is a flow-based programming tool for IoT applications.


This project is a Node-RED add-in. This project has separate nodes for the OMF Type, Container, and Data messages. It has a shared configuration node for the URL and Header information needed to send messages. All the fields are mustachable and the data fields in Data have an added mustache-ability to let you access properties in an object array.

For example. If you have a field with the value: {{payload.url}}. And the node receives a message containing: { date: "Monday" payload: { url: "", } } The resulting field will be set to: "".

These nodes will not send the information but rather are to be connected to output nodes. It is possible to use a property from the flow context or global context. Just use {{}} or {{}}.

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

The added mustache-ability is only currently on OMF Data value fields. This allows you to get loop over an array of objects and get values out of it. You can specify the object's property with {~[property]~}. Such that a lookup of "{{{payload}}}{~Temperature~}" goes to the msg.payload array and loops over the various objects in the array and assigns the property Temperature to the specified property name. Note only 1 {~[property]~} allowed in a field.


A sample flow is included in Flows. This uses wunderground nodes to generate the data. The URLS to send OMF messages to are removed. If you are connecting to OCS you will need a producer token to connect. To get access to OCS click here.


Node-RED An OMF accepting endpoint (Connector Relay, OCS, etc...). You can also just route the messages to a debug node and view it in Node-RED.
