Do you have problem with IKEA smart lamps (Tradfri) flickering / blinking / flashing when off? My lamps did this during the night when ruined off, short bright flashes, pseudo random thought the night. The bulb was not slowly dimming upp and down it was more like 1ms flash and then they go dark again. Three lamps was on the same connection and they did not flash in sync. Extremely annoying behaviour from lamps that is supposed to be smart…

But now I think I have found the problem, they where connected over a dimming switch which office was turned to max. When I removed the dimming switch from the circuit the problem has not been seen. At least in Sweden most modern houses have dimming switches all over the place so this is going to be a problem for IKEA, they need to find a solution. It is going to be very frustrating if people need to call an electrical to remove in wall dimming equipment.

The lamps where connected to the IKEA router/gateway. I have not Hue bridge to test them with in case it is a software problem. Hue lamps connected to the same dimming switch do not flash randomly, so they do not have this problem.
Normal tungsten or LED bulbs also work, only IKEA TRÅDFRI show this problem.

Since the dimming switch (Elko dimmer) is bypassed, everything is fine!
