Third Reality Smart Switch Gen3 is a simple solution for automating your wall switches. It mechanically turns existing Toggle or Rocker switches on/off. Smart Switches can be placed next to each other in 2-gang, 3-gang or 4-gang switches. Use with Echo smart speakers that have ZigBee or with compatible third-party Works with Alexa ZigBee hubs. Customize your Smart Switch by renaming it and creating automated routines using the Alexa app.
