Hi,

before you push this to npm can you please check the packaging guidelines - in particular the naming. [https://nodered.org/docs/creating-nodes/packaging](https://nodered.org/docs/creating-nodes/packaging)

We try to keep node-red-node-... for nodes that are maintained by the core project and node-red-contrib-... for 3rd party nodes. Also please note we already have an LCD node for Pi here - [https://flows.nodered.org/node/node-red-node-pilcd](https://flows.nodered.org/node/node-red-node-pilcd) so we would rather you worked with us to enhance that, than create another node that may confuse users.

Many thanks
