Oh great! In that case, getting to Tulip shouldn’t be that hard.

I’d recommend starting with [this guide](https://support.tulip.co/docs/how-to-use-serial-with-node-red-1). Two very important notes:

1. The pump **must** be plugged into Edge IO **before** EIO is powered on, so EIO can identify the occupied port. This is a known hardware limitation for Tulip Edge Devices.
2. The Serial nodes only work if there is no other process using the Serial connection; in other words, be sure that the [“Generic-Serial” Tulip driver is turned **off** on your Edge IO](https://support.tulip.co/docs/how-to-manage-drivers-in-the-device-portal) before beginning.

I wrote [this article](https://community.tulip.co/t/uart-bluetooth-ibeacons-and-edge-mc/7206) about a similar process as well, if you’d like to see a rough idea of how the flow might look.

I’d recommend first attempting to communicate solely over Node-RED, and then adding on the Tulip Connector stuff later. It’s easy enough to fake the Tulip Connector stuff with **Inject** nodes.
