The Best Solution for Branch & Load Monitoring

Thanks to its compact size, the SPM02/EW Wi-Fi+BLE energy meter can be installed into power distribution board, control cabinets, or even inside the loads.

No matter you are a small business owner like restaurants and shops, or a small to medium factory owner, SPM02/EW can help you understand the details of electricity usage.

Customer-Specific Cloud Integration

Users of SPM02/EW energy sensors can easily configure MQTT through the embedded webpage of the ESP32-8685 SoC.

Real-time electrical data, including voltage, current, power, power factor, and active energy, can be transmitted at defined intervals.

Three connectivity options: 1）Wi-Fi router+ Range Extender 2) Wi-Fi router 3) Wi-Fi Mesh network

Local Automation for HEMS

With the powerful ESP32-C3 Wi-Fi+BLE SoC inside, the SPM02/EW has been widely used for local control and automation for HEMS (Home Energy Management System) via HTTP and UDP.

The SPM02/EW installed at main in-coming circuit of the distribution board is typically used for automation scenes of DLB (Dynamic Load Balancing) and Zero Export to Grid for PV generation.

The Safe Way to Measure Electricity

Compared to most flexibly installed real-time energy monitors available in the market, the SPM01/EW offers the highest level of safety. Key specifications include:

  • Rated impulse withstand voltage (Uimp): 4kV
  • Rated insolating voltage (Ui): 400V
  • Over-voltage category : III

Many real-time energy monitors sold through online marketing channels do not meet the electrical installation standards in Europe, Asia, and America.
