I have a problem that I would like the groups's suggestions for help.
My detached garage has three overhead doors made by Liftmaster. These doors have the standard wireless remote control and also a wireless 60 watt light that goes on when the door opens. The light can be plugged into any AC outlet to p[ower the bulb and then receives it's on/off signal wirelessly from the door motor each time it is activated.
The problem is that the lights were not switching on and off with the door and after much testing I decided that there was RF interference in the garage causing the comm problem between the door motor and the light. More testing convinced me that it was two Netgear ethernet switches causing the interference. I disconnect the switches and the lights work.
Now this became a moot point when I installed UPB switches in the garage for the lighting but today my wireless remote control for the door started giving me trouble. The first thing I did was check the two batteries in it and sure enough they were weak (2.9v) each. With new batteries now it has the same problem so I tried unplugging the ethernet switches and sure enough the remote works well now.
So my questions:
Has anyone dealt with this in the past?
Can the antenna on the remote be improved? I think that holding the remote in your hand improves it's antenna but this is mounted on the wall.
Do you think that putting the switches in a metal box would help?
I don't like to spend on new switches but do you think that another may be better shielded?
Any other suggestions?
Mike.
