I just received Red dimmers (Firmware 1.57) and and am getting them hooked up in my home using SmartThings.
I installed the device handler, and local control is disabled. I have several 2-way switches working well with “Smart Bulb Mode” to control Philips Hue can lights. I have automations to turn on or off the Hue lights with one button press (up or down, respectively), and to dim with the switch while holding buttons.
Now I have tried hooking up a 3-way switch using a GE Aux switch (ZW2004). The switches are hooked up correctly, and both have a neutral.
param 21 = 1
param 22 = 2
param 52 = 1
Paramaters 21 and 22 have been set at the switch, as I have read others have had issue with them not being saved when set from the hub.
The Red dimmer works fine, it maintains power to the lights, and will run the automations to turn the lights on, off, or dim.
When the lights are on, and the down button is pushed on the Aux switch, the lights properly turn off, and the LED on the dimmer turns off as well. Full power remains to the Hue lights, as it should be.
However, when I try to use the Aux switch to turn the lights on, the Hue lights give a brief flash of light (100ms), and then turn off. The LED on the Red dimmer turns on, and the can lights have power (I can manipulate them independently using ST or Hue apps), but they remain unlit until I light them with the app, or turn the Red dimmer off and then on again.
I have read about some issues with others using Aux in the past, but did was unsure about the current state, from what I have read, it sounds like the new firmware (1.57) which my switches came with, had updates specifically to address Aux switches.
Is there a known issue with Aux switches and “Smart Bulb Mode”?
Any help or advise would be greatly appreciated.
