How To Connect Two Nest Hello Doorbells To A Single Chime

You can connect two Nest Hello doorbells to a single chime by replacing the “front” door connection with “rear” in the instructions. You will likely have to make a little pigtail connector from the “transformer” wire so that you can connect it to BOTH of the chime connectors on the transformer inside, and make sure that you’re following the colour-coding.

Connect your two nest doorbells to a chime using this procedure.

  1. Change the terminal to the one that corresponds to the doorbell you’re connecting.
  2. Disconnect the wire, straighten it, then trim it so that ¼th of the bare wire remains visible.
  3. Connect the wire to the front or back clip on the chime, depending on which doorbell you’re connecting.
  4. Disconnect the ‘trans’ wire from the chime’s terminal.
  5. Straighten and trim it so that 1/4th of the exposed wire is visible.
  6. Pinch the plastic clip and place the wire into the clip located on the grey wire of the chime connection.
  7. Secure the ‘front’ or rear wire as well as the ‘trans’ wire, and you’re ready to go!
