Raspian for Robots also comes with Node-RED which has https://www.npmjs.com/package/node-red-grovepi-nodes but I ran into an issue installing that. I also tried https://flows.nodered.org/node/node-red-contrib-grovepi which seems to have a similar install issue. I will keep looking into this option as well.
