some dimmer modules allow 2 switches thiese would give your original switch the low and hi dim up and down and a flick to either and back to low turn of the light.
looks suitable and the switch can work as 1 way for down one way for up.
I like it. As a refresher I provided two drawings below:
Drawing 1: Current wiring schematic for range hood
Drawing 2: Proposed Wiring schematic with Fibaro 2 Dimmer module
Drawing 1:
Drawing 2:
All correct.
Awesome, thanks again !
