I have a Leviton wireless light switch control installed to control one circuit (ceiling lights) in a 3-way configuration. There is a hard wired switch (receiver?) at one switch control, the second light switch is disabled. The "remote" unit is powered by battery and attaches to any surface with sticky tape (mine wall mounted upstairs from the switch which is controlled). My problem is that the lights go on randomly by themselves without signal from remote. This started after I installed a new garage door opener and I suspect there is interference with the remote (RF signals) from this unit. The wireless set-up does have "A" and "B" selections (different frequencies) but I have not been able to use any but the "A" configuration (perhaps the transmitter-receiver is bad?). I am not able to find users manuals, troubleshooter, or any other advice on line. Is there a remedy for my problem? Should I simply buy another unit? Thanks for any help.

Are you changing to "B" on both units. X10 Also make a 3 way wireless, if I remember it has several codes to choose from. Are you sure it only happens with the Garage Door remote and not a neighbors?

Thanks for your post. More information... 1) I discovered the "a/b" switch is located on the back of the hard wired component; 2) it isn't a 3-way config after all since a nulled the 2nd hard wired switch; 3) when both Leviton components switched to "B" the wireless seems to work fine AND I no longer have the renegade "on" activity. I did notice that the hard wired component is really hot ( I mean hot ), so I'm suspecting a fault of some sort. I bought a new wireless switch unit and will install this if this persists (who needs a house fire?)

What is the total wattage of connected bulbs?

That's a great question. I'm afraid it's a LOT (at least 600 Watts... maybe more)

Many controls only handle 600 Watts. If lights total more than 600 Watts a relay could be used to lift the load from the 3 way.
