I'm looking for a solution for connecting a smart switch to my whole house fan. I have not been able to find an exact switch available for my use. I currently have a SPDT center off switch (Up is high, center is off, and down is low). The wiring for the unit is simple, there are 2 separate wires that control the speed, the swich just energizes one of them. I would like to replace that switch but as I said, I have found no products for it. In my research I came across these products and they look promising. Can anyone enlighten me on which swich might best fill my needs, and more information on how to program it? It appears that I pick up one of these pcb swiches and program it to make sure that only the high or the low would be energized when turned on.
