I have tried a few things. I have an old mini controller (about 25 years old, but it works), a sundowner (which I haven't tried for this), a hand held (which I haven't tried), and an interface. I tried the interface & the mini controller. Somebody said I should press ON-ON-ON. I think I tried the mini controller before getting that advice and pressed ON-OFF-ON-OFF-ON-OFF. I tried sending just ONs from the computer using the interface, but the software doesn't seem to work for that.
I have had the light with the socket rocket & whatever I was using plugged into the same outlet or power strip. The instructions were clear on that bit.
