Question
Guest makli
I have Fibaro Dimmer 2 (FGD-212) installed in 2-wire setup and it's controlling dimmable LED bulb (9W LED, 230V). Calibration process successfully detected LED bulb as dimmable. Dimming is working fine and I can set various brightness levels, but if I leave the light on running on low brightness (for example around 20% or 30%) it works fine for a few minutes, but then brightness gets randomly changed without any reason and brightness oscillates up and down (drop for a few minutes, then goes up again, then even higher, then drops again, ...)
There are no commands from controller, which would invoke this operation. It also happens when controller is off. However controller is receiving information from FGD-212 about change in power consumption, which corresponds to random brightness changes visible on the bulb. Controller is not receiving any information about change of the brightness level from the dimmer during that time. Normal operation can be easily restored (for a few minutes) by setting the right brightness again via manual switch or software.
