I think you might be better off just connecting each LED to a GPIO and using interrupts to catch the state changes, and polling to monitor levels. 5 Hz is absolutely nothing to a microcontroller like the ESP32. It would be a lot easier than using RMT!

RMT is better suited to fast signals where you need to capture their shape with hardware, before the software has a chance to act - e.g. IR signals from TV remotes...
