Flickering lights? It could indicate a driver incompatibility between the bulb and dimmer.
The executive element in the ZEN77 Dimmer switches is MOSFET, a trailing edge driver. If an LED bulb uses a leading edge driver, this could cause your lights to flicker when turning on/off or dimming.
You'll also want to confirm that your LED bulbs are labeled as dimmable. On/off LED bulbs are not compatible with dimmers and will not perform correctly.
Never use a Z-Wave dimmer with smart bulbs unless you disable paddle control on them first. Dimming smart bulbs from a wall dimmer may damage your equipment.
