Hi there,
I recently installed the Blue Series Dimmer Switch (VZM321-SN) and got it connected to Home Assistant through Zigbee2MQTT. I’m still experimenting with the different parameters, but so far I really like it — especially because it works with Philips Hue bulbs, which was my main reason for buying it.
The room where I installed the dimmer has three different switches that can control the lights. I put the Blue Series switch in one of those spots. Along with it, I also purchased two of the Inovelli Add-On (Aux) switches, hoping to use them in the other two locations. My goal is to make sure that the Hue bulbs never lose power, no matter which switch someone uses.
I was able to get the main dimmer working just fine and can control the lights using Zigbee2MQTT after adjusting a few parameters. The issue I’m running into is with wiring the Add-On switches. I tried installing the first one, but I’m confused about how to wire it. None of the three switch boxes have a neutral wire, but they all have travelers. Each box has black wires for Line and Load, plus a ground. That setup worked fine for the dimmer itself, but the Aux switch only has terminals for a traveler, neutral, and ground — no Line or Load.
I’ve looked at a few wiring diagrams online, but none have worked for my situation. I’d really appreciate any suggestions or guidance on how to wire the Add-On switches properly with my current setup.
Here’s a photo of the wiring I’m working with at one of the dumb switch locations
I am hoping for some advice on how to get this working correctly. Thank you in advance!
