    Door bells (again)

    I haven't been able to find any decent icons in the usual sources to illustrate my doorbell having been pushed.

    I'd like something like a bell that's green at the start of the day but has turned red when I come home at the end of the day and it's been pushed. (I have all of this set up and logged - it's just the icons i'm after!) Anyone??

    Malcolm,
    What are you using to catch the doorbell being tripped? I tried a 12V AC relay that then closes a contact on my alarm panel but the circuit does not respond fast enough, unless the doorbell is held for about 4 seconds.

      Why not make the relay latch for a few second using a capacitor ?

        it's an SM10E Powerflash unit. Actually I'm beginning to doubt it's effectiveness - i'm not sure it's catching all the bell pushes. I'm doing some tests just now.
