Hi. I have a hallway with two dipole rocker switches, which I am able to configure to my liking, and both switches toggle the light as expected.
If I replace one rocker switch with an MS-OPS5M according to the instructions (no neutral wire at sensing switch, which includes jumpering a traveler to common on the remaining rocker switch), neither sensing switch nor the remaining rocker switch work at all.
The troubleshooting instructions that come with the MS-OPS5M suggest swapping traveler wires at either the sensing switch or the other switch, which I have tried to no avail.
I did notice on the MS-OPS5M circuit board (peeking through holes in the back casing) that one of the black wires is connected to a port labeled "black" and the other is connected to a port labeled "black/red". Does it matter which black wire is connected to a traveler or tagged wire? I have swapping the black wires (and the travelers, again), also to no avail.
I can replace the MS-OPS5M with the original rocker switch, and un-jumper the remaining rocker switch, and rocker switches work again.
I have tried 3 MS-OPS5M units, so I don't think I have a bad switch, I suspect there is something in the documentation that is incorrect, or that I am otherwise doing something incorrectly.
Are there any other troubleshooting steps I can try? Thank you.
