There are a lot of Grow Lights and Fans out there, which can be controlled in brightness or speed with the so called "0-10V" standard. Just supply a voltage between 0-10v . 0 means lowest level.

First I thought something like an rc filter with the 12V pwm would be a nice solution, but i dont think this will fit nice on the pcb.
I think the most use case would be to turn on/off the device, e.g. with an relay on the 12V output and do the adjustment additionally.

Luckily there is a thing called "Gravity: 2-Channel I2C DAC Module (0-10V)" https://www.dfrobot.com/product-2613.html
Looks like its good available. I can imagine that it is just a matter of time, until an opensource clone of this will appear. pretty useful thingy!
