    3-way ability of Ariadne CL Dimmer quit working

    Howdy folks. I purchased two Ariadni Toggler CL Dimmers about two weeks ago.

    Here is my setup:
    Installed in unheated garage.
    1 CL Dimmer Toggler is set up 3-way with another regular 3-way switch.
    Switches control 4 recessed can lights, each with a 7w ecosmart LED R20 bulb.
    The other Toggler CL Dimmer in the box is not yet hooked to anything.

    For two weeks, the CL Dimmer has worked flawlessly. However, 2 nights ago the lights began to flicker. The flickering was most notable at brighter dimmer settings, not as noticeable at low light settings. The flickering lasted for about 1 hour, then they operated as normal.

    So now tonight when I got home from work I went to turn on the lights in the garage. Nothing. Went to the other switch. Nothing. Eventually my friend came over and he flipped a switch, the lights came on. However, the 3-way was no longer working properly. It acted as if they were not wired up correctly. But they had been working correctly for the 2 weeks prior.

    Some troubleshooting I did:
    Replaced the Ariadni CL Dimmer with the other Ariadni CL Dimmer that is in the same wall box but was previously not hooked up yet. No change in operation...still messed up 3-way capability.
    Replaced that Ariadni CL Dimmer with a plain 3-way switch without dimmer. All 3-way functionality restored and works perfectly.

    I am really confused and frustrated with this behavior. The only thing I can figure is that the electronics are temperamental with the colder weather that has come in the last couple days. But, it's not really that cold for Iowa yet. Why would the CL dimmer operate perfectly with 3-way for 2 weeks and now not function properly? The dimming still seems to work the same, just the 3-way stopped working.

    Does anybody have any advice for what to try next?
