This is what I am trying to do, and please suggest the best way to go about it:
For experimentation purposes, and took over a room that has four speakers hooked up to an amp with a microphone.
I would like it that the elk can use those speakers for alarm/security purposes, but the homeseer or other HA system can also use the same speakers for announcing HA stuff (doorbell, weather, etc....)
The preferred way to do this would be for this to work while still having the microphone plugged into the amp. I have no problem putting in a particular amp if necessary.
Any suggestions?
Thanks
