Oh great! In that case, getting to Tulip shouldn’t be that hard.
I’d recommend starting with this guide. Two very important notes:
- 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.
- 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 before beginning.
I wrote this article 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.
