solved. here's how i ended up running this. i'm guessing that my doorbell has a resistor built into it, unless the led itself is acting as one (not sure if that's possible). anyway, all of my other zones with an EOLR are reading 7.1 - 7.2 volts but the doorbell zone is reading 6.3 volts. i bought a heath zentih led doorbell from lowe's a while back, not sure of the model number. but it seems to be lighting up just fine with the voltage provided from the m1 board.
i have a rule for whenever "Doorbell Zone" becomes Not Secure, turn on "Doorbell Output" for 1 second which is using one of the Normally Open SPDT outputs from the M1XOVR relay board.
Exactly what size/type resistors did you install Pete?
I guess that's the good thing about this thread still living on - somehow I missed that line from 5 months ago.W2P,
It would be "more fun" to have a little speaker outside and have a computer talk to whoever is ringing the doorbell with a bit of intelligence or a fake animated plant greeting the doorbell ringer, just moving enough to see it with the corner of your eye; but not really noticible. Maybe just moving a bush or something towards the doorbell ringer between all of the rest of the bushes.
I tried a Utilitech #0163358 from Lowe's and can confirm that it does work with the ELK M1G. The resulting zone voltage is close to 7 volts; however, the appearance is VERY poor. There is a roughly square lighted blotch in the middle of the round pushbutton and the lighted ring is very non-uniform. Most of the light appears to be going out the back of the switch.
