Explanation of `PWM Minimum` (Temperature PID)

[patschi]

In HA there's "PWM Minimum" which ranges from number 0 to 30:

But I can't figure out (easily) what these values refer to. Are those percentage? (What is 100%)

As per YAML config here:

wifi-fancontroller/modules/temperature_pid.yaml

Lines 150 to 159 in 895a55d

	- platform: template
	entity_category: config
	name: PWM Minimum
	id: pwm_minimum
	restore_value: true
	min_value: 0
	max_value: 30
	step: 1
	initial_value: 20
	optimistic: True

It also doesn't explain more. If it is percentage, I'd make it 0-100.

Next good find.

This is the minimum PWM allowed for output.
So even if the PID controller would fully turn off the fan, it would still e.g. output 20% to keep some airflow.

I will document this better.

Thank you!

Wouldn't it be better to maybe allow higher values, even such as 70% and don't lock it to maximum of 30%? I guess even allowing 0-100 wouldn't hurt?
