If you want to use two Inovelli switches (Blues, Reds or Blacks) in a 3-way, then there are only 2 ways to make this work.
1 - Bind the two switches together
2 - Control the load switch via scenes
Using two Inovellis is different than using an Inovelli in a 3-way with either a dumb switch or an Aux switch. In those cases, the switches can communicate via a traveler wire or wires. However, two Inovelli switches cannot communicate via a traveler wire. They can only communicate via binding or scene commands.
The instructions are pretty clear if you refer to the proper part:
Multi-Way (w/2+ Smart Switches)
Please use this if you have two or more switches controlling one load (NOTE: Load may contain one or more light) and are using multiple Inovelli smart switches.
Neutral Wire Installation In this scenario, your switch is installed as a multi-way switch (which means multiple switches controlling one load) with two smart switches and you have a neutral wire present in the gang-box.
Please find the before picture (shown on the left) that best aligns with your wiring and then wire your switch per the schematic. If the schematics are too small to read, you can either turn your phone sideways (if on mobile) or click on the picture to make it bigger.
IMPORTANT: Please shut off power prior to installing your switch.
NOTES: There are a few things to note prior to installing your switch:
- You will have to rewire your setup to a non-traditional way of wiring (we’re going to put 120V to each switch) so that the switch will work. Please take a picture of the before wires so that if you ever move and revert back to dumb switches, you remember what the wiring was like.
- You must use an Inovelli switch in this setup
- You must determine whether or not your hub/gateway supports Zigbee Binding (if not, the only other method is Zigbee Scene Control)
NOTE: If your hub/gateway does not support either Zigbee Binding or Zigbee Scene Control, you will not be able to wire two (2) or more smart switches together
However, If your hub supports either Zigbee Binding or Zigbee Scene Control, please move forward with the programming instructions after you wire the switches together per the schematics below:
3-Way Schematics Please see the below for if you have a 3-Way setup (ie: two switches to one load).
