    Hi guys

    Whats the easiest way to make dumb extractor fans smart?

    I have one on/off fan in my basement that I want to be humidity controlled. I'm thinking I should attach a Sonoff TH to this.

    Another fan in my bathroom.... I want this to be triggered by humidity but I also want switch control.
    I'm thinking of wiring the switch to a sonoff mini and also have a Sonoff TH that turns the Sonoff mini on when humidity threshold is triggered.

    What do you guys think?
    Is there an easier or better way to do this?

    Kind regards

    CF

    I have not had very much success with humidity control with high humidity, the sensors can get over damp and take ages to dry out, does not matter if simple display or switch, and had the extractor in my dads old shower simply run 24/7 where simply the bedroom was dry but sensor remained damp.

    The pneumatic switch [​IMG] worked well, set to run to max 10 minutes press on entering shower and press when leaving, simple. Keep it simple.
