I have been using an ELK-930 for some time to detect when the doorbell rings, and it's been flawless. Unfortunately my old doorbell just died and I had to replace it. The old one was mechanical with a solenoid that would strike a metal bar for the sound. The new one is fully electronic with no mechanical parts. The ELK-930 does not detect the doorbell button push anymore, and I'm pretty sure it's because the new doorbell doesn't draw enough current (900 mA minimum is what the manual states).
Does anyone know how to get around this? I'm thinking I could put a resistor in series to force more current draw, but my electronics knowledge has faded over the years and can't remember how to calculate the appropriate value resistor, or what power rating I should choose.
Any ideas?
