• The Nest Hello door bell requires a 16 to 24 V AC feed, usually via transformer off your home circuit breaker. If you see a transformer there, you can check the voltage with a cheap multimeter. You can remove the current doorbell and check the voltage there, as well. If you have the right voltage, installation was a breeze. It took about an hour total. Hooking into home WiFi was facilitated by having a Nest product (smoke/CO alarm) already in the home network.
