Hi,
This code also appears to be a substantial copy of the official node-red piface node maintained here: https://github.com/node-red/node-red-nodes/tree/master/hardware/PiFace and already published to npm as node-red-node-piface
You have removed the Apache license from our code and attached an MIT license - that is not acceptable.
As per our packaging guidelines, please use the naming prefix node-red-contrib- with your own nodes.
Nick
