Smart Meter — Monitor Your Power Smartly
Why you need it?
Real-time, whole-home energy monitoring | Automatic detection of surplus energy | Enables zero-feed-in solar power usage | Optimised with EcoFlow's OASIS algorithm
Implement Whole-Home Intelligent Power Monitoring for the STREAM System
Home appliances such as lights and built-in kitchen appliances cannot be monitored by plug-and-play smart plugs. In this case, a smart meter is needed to monitor the electricity of the entire house, thereby enabling the system to automatically schedule.
Pair with STREAM AC Pro for Photovoltaic System Energy Storage
Due to its AC coupling design, STREAM AC Pro can be easily retrofitted to existing solar systems, allowing for plug-and-play energy storage integration. By simply adding a smart meter, the system can determine when to charge and when to utilize AC Pro for household electricity offset, maximizing solar energy utilization.
Easy to Install
It only requires simple installation and connection, without incurring high installation costs or the need for circuit modifications.
Unlock the Full Power of OASIS with Smart Synergy
Your EcoFlow OASIS experience reaches its true potential when paired with our AI-Optimized Smart Meter – the missing link that transforms data into actionable intelligence. Like a symphony conductor connecting instruments to harmony, our hardware becomes the foundation for your software's brilliance. Real-time energy insights, precision load balancing, and adaptive AI predictions activate only when Smart Meter meets OASIS platform, creating a closed-loop ecosystem where every watt tells its story.
The Smart Meter isn't an accessory – it's the kinetic key to OASIS's latent power. Purchase yours today and watch your energy ecosystem awaken.
