Let me reword my problem/what I'm trying to solve. Hydroponic greenhouse, tank of liquid/soup/mix 24" deep. Right now I have a float, old curtain rod, 1/2" wire glued every inch, a microswitch connected to a PSC-01. And it's working. As the pump runs I get F8 On, F8 Off...... I want to totally switch to my RasPi/CM19a. I went looking for X10 ... sends a wireless sig. So question: DS10a? with a magnet every inch? 2in" 4in". I assume a 10a sends one closed or one open and not open,open,open........ Or a PAT01?
Thanks
