Hello! I have a little problem with my project. I need to diplay text on my lcd 1602, with i2c and i can't do that. I read the older topics. I tried with several libraries. It works perfectly with Python code, but i need to display in Node-red . Can you help me? what is the solution? ![Captură](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/8/0/80b00a52201f5377cab6476d64c4502a457e5372.png)

I don't know about the i2C nodes (someone else may be able to help you there) but if you have a python script that does what you want you can call that from an exec node in node-red.

There is a node.js package which may work for you. You can `require` the package in the globals section of your settings.js file and then `global.get` it in a function node.
