New Installation - Caseta Pro Dimmer with Mechanical Toggle

Hi All,

I need some help with my wiring setup. I am looking to do a Caseta Pro Dimmer (PD-10NXD-XX) with a Mechanical Toggle Switch.

First Photo - previous switch wiring
Second Photo - New Dimmer(s) installed. Left side is the Dimmer with Mechanical Switch Installation.
Third Photo - New Toggle Switch Wiring.

Notes:
The Dimmer works fine in this setup. The Mechanical Toggle doesn't work at all.

If I revert the toggle wiring back to the original wiring as per below, the toggle will work, but the Dimmer does not recognize when the lights are on or off.

The previous toggle setup wiring was:
(1) White wire in top left
(2) Gray wire in top right
(3) Gray wire bottom right (different screw color)

There is also another white wire in the mechanical toggle box that is capped off with the ground wires.


Thanks in advance for any help you can provide me.

If your working with a 3-way circuit ( 2 switches at different locations controlling the same load//lights) you must follow the wiring directions in the advanced guide and use Pico remote with a wall mount adapter for the electrical box.

On Page 25 of the Advanced guide it does show how to use the Pro dimmer with a mechanical switch for 3-way circuit. Keep in mind the mechanical switch location will have no dim/bright or favorite control. For that reason alnd uniformity i’d Recommend a Pico with wall bracket (adapter).
