Outlet 2 and Outlet 3 have the same readings as each other but are different from Outlet 1. . I ended up dropping in the aeotec bypass in and it ended up working out. Terminals marked for easy identification and fast wiring, all mounting hardware included. Even if somehow the voltage was emanating at the receptacle, #14 or #12 wire over a short run doesnt have anywhere near enough resistance to bleed off 30 V. This makes me wonder if you are seeing induced voltage. I get 30 volts when measuring neutral to ground, I get 60 volts when I measure neutral to live, and I get 120 volts when I measure from live to ground. These conditions can go undetected for a long time. The hot arrives on the white, passes through the switch and returns to the light via the black. I appreciated his concern and asked if I was right to be concerned at the voltage readings I was getting. By the way, the wiring in my house is all aluminum. Unless you have a low-inmpedance meter (which you probably dont), then there isnt any real way to tell if what you are measuring is true or ghost (induced) voltage. I will draw diagrams to attach to this topic. I checked it out with my multimeter, and I tried it in a different closet. This is true for both smart switches and dumb switches. Attached it; problem solved. This splicing method will prevent the load of the circuit from passing through the outlet, however the circuit load path will now go through the splice instead. You can think of this as the source voltage available at the receptacle. When the Inovelli is off, you have 0 VAC at the Inovelli Load but 30 VAC at the receptacle.
