I've bought two wireless doorbells, one a B&Q cheapo and another a Byron SX15i cheapo from ebay. Both displayed the same problem - OK to set up, work fine, and then start randomly ringing themselves within an hour of being set up.

Random rings are truly random - no regular time pattern present, long periods of zero activity, etc etc.

In the absence of possession by the devil, and ruling out nearby other houses' bells (I have tried every one of the 16 different frequencies on offer), I can only presume there is "something" in my house (or a neighbours) that is triggering the ring - perhaps the heating system, or just a switch or something else generating the right sort of rf signal to cause a problem.

I really want to be able to use a wirefree device as there are limited options for wiring from the front door to a sensible location for a bell, and we've just decorated so I don't want bell wire all over the place.

Do any of the brands do a "better" type of RF transmission that might not be so subject to this sort of interference?

years ago, we had a rather trendy (corded) phone which used to ring each

Possibly your door bell is ringing for a similar reason

then suddenly fails to work until the batteries are taken out and put

I bought an Aldi £5 effort - seems to work fine. They have some

What frequency do they operate on. could you not try to find a receiver
that covers them and see what crud is there when it rings?

Weather stations, dear boy, weather stations.

We recently bought a wireless doorbell, and it too rang at random
intervals, sometimes with a very strange ring. Eventually I guessed it
might be one or both of our weather stations. I removed the batteries
from both, and the phantom doorbell stopped.

Problem then was, we wanted to keep the weather stations *and* the
doorbell. So I opened the doorbell controller, and discovered a couple
of pots (variable resistors) inside. I reckoned one of these was an
audio volume control, and the other was an RF sensitivity control. By a
process of scientific investigation (aka knob twiddling) I was able to
reduce the RF gain to a very low level, sufficient to receive the door
bell but insufficient to receive the WX stations. Now everything works
well without mutual interference.

Try to source a Friedland EVO range of wireless doorbell. They use a
pairing system which means that they not only need to see a
transmission from the bell, but a transmission with the correct code
before they will sound. Not cheap, but very reliable and nuisance free.

The list price is high, but the Amazon link that I quoted for the Decor

I've been using cheapo Wilko wireless doorbells for the last few years
and found them effective and reliable. I have to say that in the
plural, not because they are unreliable, but because I'm unreliable
and keep dropping the blooming receivers - sometimes through fatally
long distances.

It's a very large building and I often take the receiver out of range
of the transmitter but when I return, it is still locked on. I've had
about two false alarms from it over about four years. On each occasion
the receiver has played a chime different from the one set at the
transmitter and I have no idea what caused it. I can live with that.

The Wilko unit costs about six quid so maybe it's worth buying one
just to find out if it works for you.

You could run the bellwire through oval conduit or even a narrower pvc
'pipe' and that could be glued straight on to the uPVC frame with the
silicone sealant of your choice. If done carefully, you might soon not
notice the conduit.

Not had this problem, but my experience FWIW.

Byron seems to be one of the more solid makes, and have a handy "sender"
which you can wire into an ordinary low voltage bell circuit to actuate
one or more of their wireless ones. In fact it will also "drive" an
Omega one, I now have wireless mains plug in sounders around the house,
and one which can go into the shed or garden if necessary.

Readily available from eBay, a bit more expensive than the cheapest shed
ones.

Been there, done that. Binned the lot and spent 40 quid on a Friedland one

http://www.screwfix.com/p/friedland-...twinpack/50749

Main unit is in the kitchen but can be taken out in the garden etc if wanted.

Second unit sits in a mains socket upstairs.

Been brilliant for many years. Required a new set of batteries in the
reciever (2 C cells) after 4 years or so. Button press still going strong
after 8 years.

Whether this is indeed bollox is an interesting point, but we do actually have a cheapo wireless weather station, so it is possible that cheapo WS with cheapo bell might be the issue.

Bell was ebay, so that will be written off to experience.

Problem is, SWMBO likes a "proper" bell ringing, which most of the expensive other makes don't do, preferring some 90's style synthesised tune or other such dong-ing.

Anyway, for whatever reason, no matter which frequency I try, it still rings randomly, so sommut is wrong.

Will try an alternative brand more expensive unit taking advantage of distance selling regs and see what happens.

Hi there, it's the frequency, I just moved and mine was ringing when no one pressed it and guess what, so was my next door neighbours! Lol! Because they both work off the same frequency so press one and they all go off.

Hi there, it's the frequency, I just moved and mine was ringing when
no one pressed it and guess what, so was my next door neighbours!
Lol! Because they both work off the same frequency so press one and
they all go off.


I have a Friedland Evo 433MHz - no trouble in 5 years, original
batteries too!

No nearby radio amateurs on 70cm, then?

If not presented with both the right frequency and the correct code,
they should not ring. You get what you pay for.

I recently got:

Friedland 200m D914 Libra Plus Wirefree Portable Chime and Push

for my somewhat hearing-challenged mother. Much better than I expected
and you can get a dongle so an incoming phone call also makes it sound
(with a different effect).

Except that equipment like that can be overloaded and driven to places
you don't want it to go like TETRA Airwave transmitters nearby..
