EcoSmart Live is designed such that your Radion, VorTech, and Vectra store their scheduling data. If your ReefLink goes offline or is disconnected for any reason, your EcoTech devices will continue to follow their schedule. Furthermore, your EcoTech devices have built-in memory. Should you disconnect power from your Radion, VorTech, or Vectra, they will resume their programming once power is re-applied. The ReefLink is simply a bridge between the internet network and your EcoTech devices allowing for cloud control.
