Communication is two-way encrypted, protecting your network security and privacy.
●START SMART! A YoLink hub is REQUIRED for full functionality, including for the app to work, but your hub is compatible with a growing family of smart products for home and business, from smart locks to smart light switches and more! Search for B09FSS95G9 for a SpeakerHub (our audio, talking hub) or B07TQLKQLJ for the original Hub.
