Hardware-triggered presets

Questions
1

I’ve set up WLED with a D1 Mini (ESP8266-12F) and a WS2812E led strip and it is working quite well so far.

Question:
How can I assign WLED presets to ESP8266 inputs, so that e.g. preset #2 is turned on when IO2 on the ESP goes high?
If that is possible, would the module still require WiFi access when running in that mode?

Thanks …

Use buttons…

Thanks for the hint. :+1:

It looks as if I’m limited to 2 buttons/switches… or how would I increase the number?

By custom compiling and adding -D WLE_MAX_BUTTONS=x in platformio.ini
ESP32 offers 4 buttons by default.
