Flickering light with 2 in 1 in a 3-way no neutral.

I just finished wiring an Inovelli 2-in-1 switch in my hallway in a 3-way setup and I am looking for some guidance.

The power comes in at the light fixture, so there is no neutral in either switch box. In the main box I have a 2-wire coming in with the white being hot, and a 3-wire running between the two switch boxes.

In the main box, I have the white from the 3-wire and the black from the 2-wire tied to Line. The black from the 3-wire is on Load, and the red is on Traveler. In the other box, the red is on Traveler and the black is on Neutral.

Originally I was going to install an Enbrighten motion switch in the hallway, which is why I had an Enbrighten add-on in place, but once I realized there was no neutral I scrapped that idea. Since I had extra Inovelli switches, I decided to install the 2-in-1 instead. I ordered an Inovelli aux switch, but it will not be here until the 12th.

Right now the switches work from both locations as expected, but when the light is on, the fixture flickers and the LED bar on the Inovelli flickers as well. The switch is currently set to On/Off mode and configured as a 3-way with Aux.

Any insight on whether this is a wiring issue, configuration issue, or just a temporary problem due to using the Enbrighten add-on instead of the Inovelli aux would be appreciated.

In the main box, the WHITE from the 2-wire goes to the Line, because that’s the hot conductor.

The Load is the black from the 2_WIRE

It’s always best to refer to the Inovelli wiring diagrams at https://help.inovelli.com

Sorry I mixed up the 2 wire and 3 wire when writing it. I followed that diagram. I have the white from the 2 wire on the line with the black from the 3 wire. The black from the 2 wire is on the load. The white on the 3 wire is capped in both boxes.

What is the load? Type of bulb, wattage, etc.

Its a single 26W CFL bulb, 1650 lumens.

My best guess is that you need a bypass at the light. It sounds as if the switch isn’t being fully powered because of the non-neutral configuration.

I swapped the CFL bulb with a Philips dimmable LED 5W (60W equivalent) bulb and the flickering stopped and the switches work. When the light is on the LED bar on the inovelli top half blue and bottom half red and I never made any changes to the LED bar parameters. Color when on is set to blue & all of the DefaultLed#ColorWhenOn & DefaultLed#ColorWhenOff are the same.

When on:

When off:

It’s either defective or has a wonky setting stuck. Factory reset it to see if that resolves it.

That fixed the red LED, thank you! I appreciate you helping me out.

Now when I turn the light on, the LED bar comes on bright for a second and then dims like the switch is off. The light will randomly shut off and the LED bar cycles cyan-blue-green, then the light turns back on and led bar goes back to how it was.

There’s no real pattern to it, sometimes it’s a few minutes apart and sometimes it happens again pretty quickly. Since it’s a hallway it’s not a huge deal for now. I ordered a bypass and I’ll install it when it comes in, hopefully that fixes both the LED bar behavior and the random shutoffs.
