I need something to physically operate those stiff fan isolators. All three of my bathroom extractors work by turning those on and off directly. One was pullcord and the cord broke, the other turned out not to have any means to turn on after being fitted, and the other is connected to the light being on but I want to keep the light live all the time so we can use a smart bulb. So those are the three reasons.
Now I have seen those neat little switchbot things, but I have heard they can't manage stiff switches.
