  • Open API Access & Smart Platform Integration: Supports integration with platforms like Home Assistant via HTTP (JSON-RPC 2.0) and MQTT. When combined with a solar PV system, it enables “zero feed-in” control—preventing excess solar power from feeding into the grid and improving energy efficiency in solar-powered homes.
  • 6-Channel High-Current Monitoring with Flexible Merging: Monitors up to 6 independent circuits, each supporting up to 120A. Channels can be flexibly merged to display total power usage. Ideal for complex setups—monitor both individual phases and total consumption of a 3-phase heat pump, for example.
  • Minute-Level Monitoring & Multi-Dimensional Data Views: Tracks energy consumption in real time at the minute level, and offers daily, weekly, monthly, and yearly visualizations. Includes free cloud storage with minute-, hourly-, and daily-level data uploads. Daily data is retained for up to 5 years with no subscription required.
  • Renewable Energy Input Monitoring: Accurately monitors input power from solar panels, wind turbines, and other renewable sources—supporting clean energy management and system optimization.
  • High Accuracy & Detailed Power Parameters: Delivers measurement accuracy within ±1%, and provides key electrical metrics including voltage, current, active power, and power factor for each monitored channel—enabling precise energy management.
  • Local Web Interface, App-Free Operation: Offers configuration and data access through a built-in local Web UI. Once connected to Wi-Fi, you can access the device via its local IP address within your LAN—no mobile app required.
  • DIN Rail Mounting & Compact, Certified Design: Designed for standard DIN rail installation with a compact footprint. Features flame-retardant PC housing and a high-gain antenna for stable performance. Certified to EN 61010 standards and backed by a 2-year warranty for peace of mind.

Unlock Smarter Automations with Home Assistant and Other Third-party Platforms

For example, when EM06P detects surplus solar energy at home, it can automatically turn on the washing machine to consume the excess - reducing feed-in to the grid.

For example, when EM06P detects surplus solar energy at home, it can route surplus energy into the battery with your PV system to enable zero feed-in.

For example, when EM06P detects surplus solar energy at home, it can automatically turn on the electric water heater to consume the excess, reducing feed-in to the grid.

For example, when EM06P detects surplus solar energy at home, it can automatically turn on the EV Charger to consume the excess, reducing feed-in to he grid.
