A project log for IoT RGB LED Matrix Controller (ESP32)

This project is about building and programming an ESP32 based controller for a 32x32 RGB LED matrix, controlled from Node-RED over MQTT

The RGB LED matrix has been functioning for a couple of months now and I have noticed a few bugs. Overall checking this display has become part of my daily routine. I especially like the full control aspect of it (software-wise).

Thanks to its versatility I was able to decide exactly what to show according to my needs, this is how I use it:

I show the time and date, the outside weather, temperature and humidity (To = temperature outside, Ho = humidity outside).


For both of these cases a power cycle helps to put things back in order.

Another issue is that the OTA update does not work, I am not sure why that is, but I cannot upload code over the air as the ESP does not show up in Arduino IDE.

That being said these problems are rare and the hardware is solid. If you want to build one please do and send a picture of how you use it :)
