When using the verified Alexa Plugin the doorbell shows up but doesn't detect the button being pushed. However, the Doorbell trigger accessory does work but that appears in Alexa as a switch. Alexa can't use switches to trigger events or routines so maybe with a few conditions we can make it behave differently if you are using Alexa.

**Describe the solution you'd like:**

First check and see if it's just a bug or if this feature isn't available add a condition that would allow the user to specify if they are using Alexa to have it behave differently.

**Describe alternatives you've considered:**

The motion detection also works great with Alexa to trigger a routine maybe we can trick the doorbell trigger to be a motion sensor. I prefer just to make the doorbell work because Alexa has an awesome built in menu if the device is a doorbell.
