I've bought two wireless doorbells, one a B&Q cheapo and another a Byron SX=15i 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 s=et up.Random rings are truly random - no regular time pattern present, long perio=ds of zero activity, etc etc. =20In the absence of possession by the devil, and ruling out nearby other hous=es' 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) tha=t 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 opti=ons for wiring from the front door to a sensible location for a bell, and w=e'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 b=e so subject to this sort of interference?Matt

years ago, we had a rather trendy (corded) phone which used to ring eachevening at a fairly predictable time. I noticed that this coincided with aSAA Jumbo passing overhead somewhat lower than other planes from Heathrow.Possibly your door bell is ringing for a similar reason

Wireless doorbells? Any "better" brands or frequencies?

Cool - what device is that Bob?

Asterisk box driving a USB relay, and a standard 12 volt door release. When I wired the house, I ran a multiway cable from the phone wiring centre (a Krone 301A) in the wall down to a box by the front door.

Sorry, that was describing the phone operated door release that I was asked about elsewhere....

I'm not sure yet, is the answer to you. Another USB interface, probably build this one myself, to detect the door push and tell Asterisk.
