I’m sure if this is the right place to post this but here goes.
I have an 8 x 32 LED matrix that I control with an Arduino to scroll short messages, Merry Christmas, Happy New Year, Happy Birthday, etc. I was looking to see if there is a way to integrate that into HA so that I can use an automation to change the message being streamed. ESPHome doesn’t look like it will work since it replaces the code on the Arduino and I didn’t see a way to control the LED matrix.
Any ideas?
