  2. Connect the doorbell to the output of the transformer. There will be two terminals at the output of the transformer and two terminals at the doorbell. Connect one terminal of the doorbell to one output terminal of the transformer. Now, connect the doorbell's second terminal to the transformer's other terminal. It is AC, so you don’t have to worry about the polarity (positive or negative).

  3. It is time to install the chime unit. Find a suitable place inside your home. There are two types of chime units available. One directly goes into the wall socket, and the other one requires batteries. If it requires a wall outlet, you can insert it without any hassle. But if it requires batteries, install the batteries, and you may also need to drill a couple of holes in the wall to mount it.
  4. Turn on the doorbell. Install the required app on your device and connect the doorbell to the Wi-Fi. Finally, test the doorbell and check whether it is working fine or not.
