Wow !!!! I can't believe for once , I am not the one that had an issue. Local Big Orange finally had them in stock, so I grabbed one just to test . ( running out of light sockets that don't already have either TCP or GE bulbs , or on a connected switch). The card in the pkg said to install the light, but leave it off until after you start to pair. I did that and although a lot slower than the GE bulbs and no blinking or other indication it was pairing it did pair with A+ fine. Showed up as a multilevel switch .
I can dim it fine through either the app or the LCD, BUT it does not show the proper power level. If I slide down to say 25% it will dim, then the slide indicator goes back to 99% even though the bulb remains at the 25%. Turning it off/on, it returns to the prior brightness although always showing 99%. To adjust brightness just ignore the percentage reading and slide up/down until it is at the brightness level you want.
