Hey guys - hoping I can get some help… I recently picked up three red dimmers and got around to attempting to install them. I am in a relatively new home less than seven years old everything has neutral. I installed two of the dimmers in single pole configuration with neutral and they both seem to work fine, minus some humming when I put my ear close. The major issue I have is with my three-way installation in my kitchen. I believe I have everything wired correctly as per the three-way with a dumb switch with load in the box.
My issue is that when I turn them on or off the pulse continually. Even when they are at their 100% brightness they continue to pulse, occasionally they will even turn off, until I power the switch back on again. The dumb switch and the three-way are working correctly in that they can turn the lights on and off independently, but the pulsing is always there. Interestingly the buzzing/humming coming from it seems to fluctuate at the same frequency of the posting of the lights.
The exact same dimmer switches in a single pole configuration controlling the exact same LED lights in my ceiling have no issue, it is only this one in a three-way configuration that behaves this way. Any ideas? I’ve checked all my wires are tight, and I think the wiring is correct. I have the correct device handler in smart things and it’s configured correctly for three-way with a dumb switch. The switch is reporting in the app only 33 whites so it seems well within the operating limits, not to mention the same switch in a single pole configuration works flawlessly.
I tried to capture the behaviour in a video here https://drive.google.com/file/d/1Dv6O6vaNOOw5FycEcr8jPRpu6ZVFFuad
