Hi

I've just got one of those cordless doorbells, but all is not beer and
skittles.

Sometimes it would just decide to ring all by itself - so it was actually
playing 'knock down ginger'.

Now, after some heavy rain - it don't not work at all.

Are they just a waste of space, or should I get the WD40 out?

They are of variable quality. The more expensive ones have much better
range and have better weather sealing.

Have you tried changing the code of bell and button from the basic
settings? A close neighbour might have the same system also set on the
default code.
