The MIMOlite will work. The NO and NC contact points on the MIMOlite are absolutely dry contacts. You would need MIMOlites (one for arm, and one for disarm). You can modify the MIMOlite device type to operate as a momentary relay (with adjustable timing). This is how I integrate my doorbell. More info here:
Continuing the discussion from Working MIMOlite Device Type with Sensor :
I integrated my doorbell today using a MIMOlite with the device type linked above. I have a dog who loves to bark at the front door whenever the doorbell rings, so I’d really rather get a push notification and have enough time to get her leash on, and then calmly go answer the door. If I don’t hear my phone, I still want the doorbell to ring on repeated presses.
So I wrote this SmartApp. Perhaps it will be helpful to others. It can be easily modified to use other hardware.
I’ll add pictures of the wiring sometime soon…
First, disconnect the wire that leads from your doorbell button to the doorbell transformer and the wire that leads from your doorbell button to the doorbell chime, and connect those to the cont…
The Linear (GoControl) Isolated Relay is another one that will work for you:https://www.amazon.com/GoControl-Z-Wave-Isolated-Contact-Fixture/dp/B00ER6MH22
