Is the Google Nest doorbell waterproof?

Both the wired and wireless Google Nest doorbells come with an IP54 rating, which means that the devices are protected against water sprays and dust. That said, the IP54 rating does not make these devices waterproof, and they should not be submerged or soaked in water. The doorbells can tolerate splashes of water, such as from rain, but nothing more than that.
