TP-Link's latest Tapo smart door lock sounds like a great bargain

The Tapo DL100 Smart Deadbolt Door Lock might be one of the best deals in smart home devices

Smart door locks can get expensive quickly once you tack on a bunch of features, but TP-Link’s latest under the Tapo brand seems to defy that. You can unlock it using a code, a physical key, the Tapo app on your phone, or your voice through Amazon Alexa, Google Assistant, and Samsung SmartThings. Some features missing from the DL100 are a fingerprint scanner, Apple HomeKit support, and alternative color choices (in case matte black isn’t your speed).
