I have an existing wired doorbell, button at the front door,
transformer in garage, sounding unit in the main hallway.
I'd like to add a sounding unit on my patio.
Any cute ways to do that without stringing wire thru a very
Maybe some add-on RF gizmo?

Mine's not wired and has batteries in button and receiver unit.
Believe you can buy these with more than one receiver.
Otherwise with what you want, you can try searching for some sort of
wireless attachment for what you have.
I see a potential problem.... What if you are next door sponging tools
off the neighbor.... You might consider replacing the interior sounding
unit with something like this....
*I installed the Extend-a-Chime for a customer. It has a little device that
gets wired into the door chime and a remote plug-in module that chimes when
the doorbell button is pushed. I think that Smarthome.com has them.
I did just that. I started with a cheap wireless doorbell, but I
certainly didn't want two buttons at the front door, and I didn't want
to have to maintain a battery in the button.
So I took the button contacts in the wireless button and ran a jumper
between them so they were always closed, and I ran wires from the
existing transformer to the the battery connector in the new button.
Well, one wire started with the wire that was only hot when the existing
button was pressed. Then I put in a small diode to change part of the
transformer output to DC. My button was iirc 9VDC and I have the higher
voltage transformer, which I think is 18 volts, or lower. So
rectified it came out to 9, the rectified it came out to about 8 or 9.
The wireless button is attached to a floor joist, next to the
transformer and basement door bell.
The receiver is plugged into the 2nd floor hall.
If someone is really quick with the button, they can ring the front hall
and basement bells, without giving the button enough time to start the
second floor noise-maker going. But so far, I don't think that has
happened for others, only for me during testing.
