We have a Lutron Caseta dimmer switch which controls a set of four downlights.
I tried replacing the bulbs with Hue downlights (knowing full well that these wouldn't play well with the dimmer, except perhaps at maximum brightness), and observed the following behaviour:
- None of the lights would receive power when all four downlights were smart bulbs.
- The lights would all receive power if three downlights were smart bulbs, and one downlight was the original regular downlight. However, in this state:
- The smart bulbs pair and operate properly, except that:
- If the smart bulb's app-based dimmer was set to below 50% brightness, then all the bulbs, including the regular bulb, would turn off completely instead, then all four bulbs would turn back on again about two seconds later.
What could be causing the app-based dimmer to cause the entire circuit of lights, including the regular bulb, to briefly turn off then on again?
