Thanks for that thgoebel thats really good to know.
It would be really great to have more support for a product like this, I am finding a lot of consumer devices running the controls of 0-1v. (I am used to it at work in the industrial sector where 0-10 or 1-24v is common)
I am looking to purchase this 2 of these fans for both my remote kitchen exhaust and also my Makeup air, and would like to control it via Shelly devices.
But looking at the manual it seems that PWM (0-10v) is available for the speed control.
Could I use a Shelly RGBW2 as a fully variable control for this via PWM? From my checking of the manuals this seems to be pretty straight forward..., I assume I could even skip the "ground" as the fan is already powered and this is just providing the input
Bottom left diagram is what I am thinking.
