I have an configured and esphome with a flow sensor and a servo, this to control a flow in a pool system.
Manually I can read and change the servo to the correct flow speed. But I want to automate that.
The flow should be 0.95L/min and the servo setting goes from 0 to 100. At the moment manually at 48.
I think I need some sort of PID control to automate it, but the climate PID expects a temperature sensor…
That would work, the only problem is the water coming in differs sometime in flow. Due to filter getting full or a speed change of the pump. So that why I am looking for some automatic… Now I manually change
the setting daily.
The other way would be to try faking it, create a template sensor which takes the flow, and forces it to be a temperature. And similarly for the servo.
