WaveForm is the ESP8266 function which does perform way more accurate than ESPEasy's own scheduler as it uses a low level timer.

ESP8266 does support sending a "wave form" with quite accurate timings.
It allows timings upto 15+ seconds "high" and "low" timings including some set repeat option.
These accurate timing functions are not present for ESP32.
But the ESPEasy scheduler can still achieve quite accurate timings, depending on the system load.
The
longpulseandlongpulse_mscommands now have optionally 2 extra parameters, to allow for low frequency PWM which was not possible with the normal PWM commands.For example blinking a LED at 0.5 Hz is now a single command without the need for a looptimer in rules.
Emulating some power meter over S0 is now also a single command in rules.
