Hi, I described my issue already in a topic about bypass/dimmer compatibility but I believe it requires a new topic. Scenario: - 2 x Dimmable GU10 Philips Master LEDs 5 W each on the circuit (around 11W in tottal according to dimmer measurement) - 3 wires configuration with Dimmer 2 and bypass 2 presented below - monostable single switch - bulbs calibrated after first start up - tried with 2 completely new dimmers and behavior is the same
