The strange thing is that both dimmers flicker in perfect sync. It looks as if the dimmers cycle through some sort of program. I made a call to the webshop where i bought them. He only could say that it was the start up sequence which you see after installing, but that's definitely not the case. Both dimmers are used for halogen lamps (90 and 125 Watts respectively) so there should not be a need for a dimmer bypass. Both dimmers are installed behind a pulse switch, next to each other, so they're only 10 cm apart. Maybe that's causing some high frequency interference?
I have heard that there are some problems with flickering lights when using a vacuum cleaner of a power drill. Has something to do with frequencies that those machine produce.
Not sure if there is a solution. Maybe you can send Fibaro an E-mail. But don't aspect a customer friendly response.
Wanted to buy some bypass modules for the dimmer 1 7 months after a bought the dimmer modules, the where not available anymore.
So send a E-mail and complained about this. There reaction: Sorry for the inconvenience, but we can't help you.
