Overview
Two Devices. One Smart Upgrade. Endless Convenience.
The Dual R3 controls two appliances independently from one compact module, and reports real-time energy use for each of them. It is designed for lights, fans and electronics, and it fits into an existing setup without needing much space.
Use the readings to see where power is going, and set schedules so that devices only run when you need them.
