Here's a link to one of my projects that explains how to use an ESP32 with Node-RED.

> David @dynamicdave and Paul @zenofmud are pleased to announce the release of their Grow Frame AKA Remotely Controlled Station based on an ESP32-S2 Mini flashed with MicroPython. This practical project started out as a simple temperature sensor for a grow frame (a miniature greenhouse designed to cultivate seedlings prior to planting them out in a garden) for my son-in-law. Like a number of our projects it grew and grew (no pun intended) as more functionality was added. The final result is a n…
