I managed to lay my hands on a very nicely price reduced Fallout-style ceiling fan by CasaFan.
I wasn’t sure beforehand if the power split for the lamp and the fan would be in the motor or in the ceiling cap, but I was lucky finding it very well accessible.
The brown wire is coming from the fan and the black wire from the lamp. I already put in a Philips Hue E27 lamp, which needs to be powered always to function. The fan I want to switch, so I’ll use a Fibaro Single Switch 2 to use Homey (and Google Home) to turn on and off the fan.
The only setback is that it won’t be possible to switch fan speeds with the Fibaro. Apparently there is an option to use two switches and a capacitor to make this work, but I think the space left in the ceiling cap of the fan is too small to fit all these. Picture found in a post by @danone
I’ll keep you posted on the progress.
