Just installed a pair of their Anywhere switches. THANK YOU Simply Automated, and Google search who found them.I had 2 fans in my master bath on two separate 1 way switches. I remodeled the shower / tub space into a large walk in roman style shower. I added 2 additional exhaust ports in the new shower. What to do? I purchased a 275 CFM 6 in line fan kit w/ 2 ceiling collection boxes. I built a 4 into 1 air box / manifold. I removed the fan motors from the two existing ceiling boxes. Four intakes go to the manifold. The fan goes next, then a 6x4x4 splits back into 2-4 runs exhausting out the 2 existing 4 roof vents. Without your switches, I would have need to run a traveler between two very inaccessible wall boxes. In wall medicine cabinets and internal fire blocking would have meant opening walls to run 1 wire. What a mess. Before I found you I was contemplating a complicated circuit of latching contactors/relays controlled via a Rasberry Pi board? Your solution was simple and took only 20 minutes.
