Congratulations, you've just saved yourself 25 cents a year in
electricity.
Not to mention it might not be safe if someone is standing on wet
pavement and they gey shocked by 120V.
You probably spent more in the material than if you let the Xfmr stay
on for 20 years.
Now how are you going to deal with the TV, fridge, phone, alarm clock,
microwave. Wait don't forget VCR/DVD player, cable box, heating
system, computer, sprinkler timer,

Geeze, I replaced the transformer powered doorbell in my house 10
years ago with a 15 buck wireless chimer. Couple screws and it's
done. Replaced the AAA batteries once in all that time.

$15 at 25c/year means you'll recover your costs in 60 years. But the
batteries cost, oh, $1.00 every ten years, so that's another six bucks which
will take another 12 years to recover. But 12 years means one more set of
batteries, which requires another four years. Let's see, now (mumble,
mumble, carry-the-three), ah, yes.
Your wireless solution will save you money after a mere 73 years of service.
This does not count lost opportunity costs of the original $15.

But my chimes sound better. Aren't esthetics worth anything?
Do the math.
