    Brian,  Thanks.

    I picked up an adjustable current sense relay and ran the common transformer wire through the inductive coil.   I need to take into account steady state current of two (2) video doorbells.  The LED light on video doorbells add another small amount if current.  I am hoping I can set the detection threshold to only detect the mechanical chime solenoid. I can loop the wire multiple times though the coil to improve sensitivity.

    I have it wired up temporarily until I switch to a mechanical chime and install a second video doorbell.  I already upgraded the transformer to a 16vac/30watt.  I’d post pictures of it in action, but we are not allowed to.  🙁

    If my solution does not work reliably, I’ll give yours a try.


    Thanks, again
