Initially, this setup appeared to work as desired. However, I noticed during testing that the SAGE device would stop responding after ~20 button pushes performed during a several minute period.
Since I moved on to other options, I did not try inserting resistors as some of the other posts below have suggested.
My initial experiment:
- 24VAC 750mA wall wart transformer from an irrigation controller.
- Connected doorbell button wire 1 to green/front door lead on the SAGE device.
- Connected doorbell button wire 2 to neutral wire of the transformer.
- Connected positive wire from transformer to white wire on the SAGE device.
Looking at the HE logs, the events seems to occur very quickly.
In the following diagram, per @scottgu3 recommendation, I replaced the bell with the SAGE device.
Here's the wall wart that I'm using:
And my hackish test setup in which crossing the black and red wires represents pressing the doorbell button.
