Hello! I just got two Blue switches (VZM31-SN) and am installing them both into a double gang box. The switches that I am replacing used to be dimmers. They are both in a 3-way configuration, and their dumb switches are located on the other side of the room in a triple gang box.
I have a neutral wire, so I want to use the inovellis on one side, and keep the old dumb switches on the other side.
The two switches are for my living room, and my kitchen. They are all on the same circuit.
The Double Gang Box: (This is where I would like my inovellis)
Here, the left switch controls my living room, and the right switch is my kitchen. I have already successfully installed the Inovelli on the left, and it functions as normal in 3 way mode with it’s dumb switch. The red is traveler, white is load, black is line, and other white is neutral.
The problem is this switch on the right, I’m not exactly sure what is going on or how to wire it. From the wall I have 3 wires that the previous (dimmer) switch was using. A flagged black wire (on top in the image), a black wire, and a red wire. I tested these wires with a no contact tester and found that:
- The flagged black wire never has voltage
- The black and red wires swap voltage based off of the state of it’s dumb switch.
The Triple Gang Box: (Where the dumb switches are)
Here, the switch on the left controls my kitchen (so the one i’m confused about), and the one on the right controls my living room (functions correctly with the Inovelli). The middle switch is a dimmer switch that controls my hallway, which I’m not replacing with an Inovelli (for now )
How can I wire my second Innovelli to my kitchen? What is the flagged wire? Is it the case that the line is in my triple gang box instead and I need to put the kitchen Innovelli in there? (I would much prefer both of them in the double gang if possible). And if that’s the case, could I use some wire connectors to use the same line in the double gang box for both Inovellis? (What would I do with the flagged wire?)
Please let me know if you need any more info/have any ideas. Thanks!
