This week I took another look at the project with a view to bringing it up-to-date. These are the changes I've implemented... Re-written the code using Micro-Python Removed the ESP-01S and re-routed D4 to drive the transistor that drives the relay Swapped the Wemos D1 Mini for an ESP32-S2-Mini (faster processor and more PSRAM) E…
