    Ho Ho Ho one and all,

    I have had a problem with my wireless door button for some time and now figure it is time to fix the issue.
    Being somewhat of a cheapskate, I don't want to replace everything inside when the problem is only the door push.

    But it is a non-specific brand chime and I wonder if any of the more well known manufacturer buttons will work.

    My basic question is, do all bell push button more or less work on the same frequency so all are interchangeable? Or will it be a question of suck it and see?

    Thanks and toodle pip

    To avoid interference with neighbours' door bells, or even your own if you have more than one, I expect each bell push is 'bound' to an individual bell. So any bell push you buy is unlikely to work as delivered and would need to be configured or 'bound' somehow to your chime.

    I suggest you first establish what technology and protocols your system uses and then use that information to try to locate a compatible bell push. As usual, asking the manufacturer or supplier is likely to be the best method if the information is not not already available in the user manual.

    Chances are it is a 433MHz system. The button sends a code that the chime recognizes.

    I have a SonofRF that picks up the message and translates it to create the chime via HomeAssistant.

    It is unlikely a generic one will be able to send the right code.

    Thanks for the input.

    Being the cheapskate, and having always thought the issue was with the bell push micro-switch, I have bought a new one off fleaBay.

    The bell push always works in the summer (lower humidity) but never when the humidity is high. If my fix does not work, then I will buy a whole new system; it's only the button and two mains plug-in chimes.

    I have given up to these if here is any chance of moisture around. A decent door knocker is more reliable than the cheap Chinese electronics on the market. Nothing to fail. The last one I had worked intermittently until I had a new router when went fibre, then it worked ok until rain got into the bell push. KISS principle keep it simple sir.

    Agreed. I may fork out for a new one; after all, have to assist the recovery of the Chinese economy.

    But as a 'cheapskate' measure, I have bought a new micro-switch and will do a bit of soldering.

    If it were not wanting to keep an air-tight house, I would install one of those Downton Abbey door pulls which could ring an indoor wind chime.

    We have a Friedland wireless doorbell which seems to work OK*, FWIW. We do have a porch roof that covers the bell push. It may be worth building a small cover to protect yours?

    * Oddly some people don't use it but knock on the door instead. I'm not sure why? My favourite theory is they're just too blind to see it. Maybe I should paint it flashing fluorescent orange or something :bigsmile:
    I bought two sets of the Screwfix ones (two buttons and two sounders) they all paired nicely with each other and both ring when either button is pressed, different sounds for each door, thick stone walls no problem.
