I would suggest replacing the module.  However, there is one thing
you might try.

A few years ago, a plug-in lamp module I had did basically the
same thing.  The heat sinks in those modules are small and enclosed,
causing them to get fairly hot.  Right next to this heat sink was an 
electolytic capacitor that had reduced its value to almost zero.
Replacing this capacitor fixed that particular module.

However, I had a wall switch module that would behave very erratically.
It would do as you said. (flip the switch and light would go
on then off; remotely turn light on and it would immediatly go off
again)  It would also go into "Disco Mode" all by itself.  I
came home to a back porch light that was flashing on and off all
by itself.  I replaced the capacitor in it, but it did not fix the
problem.  I scoped around but could not find the problem, so that
module was thrown away.
