Random effect on button press

Hello! Just discovered this amazing project. It works like a charm.
Have a question. Is it possible to select random effect on gpio button press?

Check out the HTTP API in the knowledge base. :wink:

Yes, “FX=~” in presets saved my day.
I own Xiaomi bedside lamp v1. Nowadays it’s not possible anymore to integrate it into, for example, Home Assistant. So, I just replaced electronics inside with esp8266 + Ws2812b. Even hardware buttons on top are still usable. Great firmware!
