Need to replace Doorbell Pro

We have had to replace the transformer and probably have old wiring - what should we purchase so we do not have to drill new holes. We purchased 2016 doorbell pro.

 To eliminate this problem should we purchase a battery pack or solar.   We the unit will not get direct sunlight but will get sun.

Hi @Moseyinn. If you’re looking to purchase a new Doorbell, I’d recommend reviewing our Doorbell Buyer’s Guide here. It will showcase each of the Doorbell models we have, go into details on the features, and demonstrate what the installation process looks like for each one. I hope that helps! :slight_smile:
