0% light flicker

[KevinJordil]

Hello,

I use this library to turn on a lamp and when I set the percentage to 0%, it happens that the light turns on and then turns off directly after.

An idea where this problem can come from

If you try 50% is the light on stable ? How about -1% , is it off stable ? 1% -> 10% seems to low of power to turn on a lamp . The value scale in the library code is 1 -> 99 .

I am just experimenting with a 200W led flood lamp and I am getting a small buzzing with lots of flicker . The only semi stable values seem to be between 70 - 88 % though still with some flicker.

I haven't tried 50% in the long term. By the way, I would like the lamp to stay off at night, but to turn on from time to time.

I'm not sure if putting -1 changes anything because in the function if it's values less than 1, the if is set to 1.

Maybe by modifying the code and letting a value of 0 pass it works?

What hardware and method of control are you using ? When you say turn on and off from time to time ,are you thinking pir/motion sensor ?

I am using the Wemos pro mini and a simple async Web server . While testing I have found that -1 absolutely turns off the Flood leds.

With a Wemos board connected to a 2CH dimmer any value < 6 makes bulbs flickering and the light intensity is quite high. if I set 6 lamps are off

@bogomips I tried with 6 but my lamp lights up. However, with 1, it's really better than with 0. I'm going to test it over a longer period of time to see if the problem is solved

I have the same problem, using 2 as minimum... have you solved it?
