I use a MIMOlite to both monitor and control my doorbell. Keep in mind you will need to make a device type for whatever dry contact relay you want that closes and then opens the relay after a set amount of time. Doorbells and door buzzers are not meant to be held open inevitably, and I’ve found that building this momentary state into the device type is the most reliable way. SmartApps that simulate momentary functions are not reliable enough.

An example device type is linked in this thread:

A sometimes-silent doorbell

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…
