Bought 5, installed and all of the LEDs still flicker, all with neutral.
Thanks for your feedback. LED flickering can still occur even with a neutral connected, as it depends heavily on the LED driver and bulb compatibility. The Shelly bypass is designed to help with low-wattage loads and no-neutral setups, but it doesn’t resolve flicker caused by incompatible or non-dimmable LEDs. We recommend using high-quality, dimmable LEDs and checking the dimmer calibration/settings.
Easy install and the led down lights no longer flicker when dimming with the Oz Smart zigbee push dimmer. Thankyou for your quick response when querying this product.
