Hi,
I am have installed 3 red series dimmers in my house and have had no issues with exception towards 1 one of them.
The issue I am having is with 1 switch which is in a non-neutral wiring with a 3 way momentary dimmer. The main switch box actually does have neutral in it, but it is wired with both line and load at the main box, and due to the location of the two switches, I would prefer to have the smart switch in the remote box location and the auxillary switch in the main box. To accomplish this, I figured I could use the non-neutral with momentary switch configuration along with a bypass since the fixture has 24 watts total.
For the wiring, I used the wiring schematic for 3-way installation with non-neutral wire setup, with some modifications to enable the smart switch to be physically located in the remote box location. I installed an Enerwave Auxillary switch into the main box, wired with the common line going into the neutral terminal. As I actually have a 3 wire romex to the remote switch, I then tied the common line to the white wire of the romex, with the traveller remaining as the standard red wire. The wire to the load is tied in from the remote box’s black wire to the load’s black wire. Lastly, for good measure, I tied the bypass from the load’s black wire back into neutral in the box.
In the remote box, I installed the smart switch with the red wire in the traveller terminal, the white wire as the line, and the black wire is connected to the load.
Once powered back up, I paired the switch to my hub and made sure to configure it accordingly, with the AC-setup set to non-neutral, and the switch type set to 3-way momentary.
At the smart switch, I am able to turn on/off the light, as well as dim and un-dim as expected, with one weird caveat. When the light is at full or near full brightness, if I click to turn off, the switch dims the light to more than half way and then returns it back to the original brightness level. To turn off completely, I first have to dim the light to a certain level, or otherwise press the off switch twice (second time as it is dimming) to get it to turn off fully.
At the momentary 3 way switch, I am able to use the lower button to dim and turn off the light, with the same caveat mentioned above. The upper button does not seem to respond at all.
Any help with this would be greatly appreciated. I hope my descriptions help to properly convey the wiring. If needed, I can try to draw up a schematic and upload it.
Thank you.
