100 to 0 switching not proper #67

We are facing an issue with a library while using the code to dim an AC fan. When we try to set the power to 0 at once, the fan does not stop. On the other hand, if we set it to 100 at once, the fan generates too much flickering. We have defined a few steps for dimming, where 0 represents 0% dimming, 1 represents 25%, 3 represents 50%, 4 represents 75%, and 5 represents 100%.

However, when we try to directly switch from 100% to 0%, the library does not generate the proper signal to handle the AC load, which leads to flickering. We are facing this issue and would appreciate any help to resolve it.

I'm having same issue using pid controller output as dimmer power setting. I've limited pid output to max 98% and now it's ok . This line in RBDmcuESP32.cpp made me to try with max 98% power but it's above my knowledge why it works.

void dimmerLamp::setPower(int power) {
if (power >= 99) { power = 99; } dimPower[this->current_num] = power; dimPulseBegin[this->current_num] = powerBuf[power];

delay(1);

}
