Ducobox silent humidity sensor installation

[donnersm]

I'm sure there must be a way because the PCB has the connector for it. Just can't find any info on how to do it.
How can I use the Duco Silent Humidy sensor that came with Duco, with the OPEN-air PCB
I have the DUCO configured as device on my home assistant but i don't see any option to read out the humidity.
Also, Wondering if the firmware will adjust the fan speed based on humidity or is that something i need to configure in home assist
The air mini was programmed for the duco by the supplier firmware version: 2025.9.1 Jan 23 2026, 14:08:16

I also would like the duco to run on a low speed when powered on. Now it starts at 0rpm and i have to switch it on manually. However, the duco box is to vent my Bathroom and i want it to run always with a rpm depending on humidity

Ok, I figured it out.
Using the tutorial within this project I was able to compile a new YAML file. Together with chatgpt and some logic sense. I wrote a script that does:
-ESPhome uses the onboard humidity sensor that came with the Duco
-When humidity rises, the fan speed will increase. ( disconnected mode with humidty)

• There is an overrule function, when active the esphome hands over control to home assistant. I am using this to manually activate the duco when the light of the toilet or bathroom goes on.
  this is my open-air-mini.yaml and disconnected-mode-with-humidity.yaml
