The SMeter-RS04 is an AI-based all-household intelligent power distribution circuit breaker independently developed for the all-household energy management scenario. It can autonomously provide power for all household devices in the event of a power outage from the grid. This product integrates multiple communication capabilities, with hardware reserved for LAN, RS485, DI, DO, CT, DRM, etc., and also supports wireless networking methods such as LoRa, WLAN, as well as Internet access channels such as Ethernet and WiFi. As the core hardware carrier of the "home energy interconnection+" integrated scenario, the product is deeply adapted to household energy devices such as photovoltaic systems, energy storage, charging piles, heat pumps, underfloor heating, and generators, enabling unified networking, data intercommunication, and collaborative interaction of various household energy devices. The device has extremely strong ecological compatibility and can seamlessly integrate into mainstream smart home ecosystems such as Tuya, Xiaomi, and Midea, coordinating the control of smart sockets, lighting, curtains, and all household appliances, and building a full-scenario smart home energy ecosystem. Relying on the built-in AI intelligent algorithm, this terminal can complete intelligent scheduling of household electricity load, refined energy consumption control, and VPP scheduling. On the basis of reducing users' energy consumption at home, it can also comprehensively enhance the intelligent and automated usage experience of all household appliances.
Easy to use
(1) Installation is simple: rail;
(2) Configuration is simple: local settings (APP), remote settings;
(3) Maintenance is simple: remote maintenance, remote firmware OTA upgrade;
(4) Usage is simple: power on, connect to network, register and bind.
General
(1) Component selection: Industrial-grade components, capable of operating for a long time at -20°C to +65°C;
(2) Communication stability: Real-time command monitoring, network disconnection detection, long-term operation detection; data is saved when the network is disconnected, and data is continued to be transmitted when the network is restored.
(4) Data security: TLS-TCP connection, private protocol, data verification, data continuation transmission (data is saved when the network is disconnected flexibly, and data is continued to be transmitted when the network is restored).
Flexible
(1) Protocol compatibility: Supports communication via multiple communication protocols;
(2) Local and remote: Compatible with the APP, allowing for both local monitoring and remote implementation;
