1 year ago @shirou93 I think the pulse_width sensor is sometimes returns 321 or higher instead of 320 when at max fan speed. This would cause the default case to which means fan speed 0.
You could try changing the max filter to the median or one of other average filters, along with adjusting the window_size/send_every settings.
And below is an alternate lambda code that allows values a range of values instead exact values which might be more reliable, and you can also adjust the buffer value if it's reading.

Hi.
great work :) Sensor fan speed working good on 0, 1 nad 2 value, but when got 3 then showing 3 and quick switching between 0 and 3. It's possible to fix it?
