Since the mail around here doesn't arrive before dark, and sometimes after 7 or 8, I need a notification device so I don't go out to the mailbox for nothing. Found these two: https://www.amazon.com/Mail-Chime-MAIL-1200-Wireless-System/dp/B00103FDDU and https://www.smarthome.com/smarthome...GfInHBfdpmaVqmeRY8jzv6qtjqBoC4ioQAvD_BwE Anybody have either or suggest any other one?
