I just hooked up a master dimmer and the companion dimmer. The master dimmer works as expected. The companion dimmer will turn on/off the light only when it's pressed. So it literally turns them off and then back on. If I hold the companion dimmer button down, the lights would stay off until I released it.
I undid the Lutron devices and just hooked up plain old 3-ways the same way and it works great. Redid the maestro and same problem.
Would love to know how to troubleshoot the issue. Thanks!
