An easier place to look (although it gets the same data as the Manage Palette, so it won't help if you've already searched there) is flows.nodered.org.
Here you can search for nodes, and it is easier to read the nodes readme so read about any prerequisites etc before you install.
There are several ways you could potentially integrate your hub with Node-RED.
- See if there is a nodejs library and write a wrapper around it to turn it into a node-red node.
- Run a 3rd party insteon-to-MQTT application and then use the Node-RED MQTT nodes ( you would also need a MQTT broker)
