EM6 6-Channel Single-Phase WiFi Energy Meter
BL0906 Energy Monitoring | ESP32-C3 | ESPHome Firmware | Bluetooth Proxy | Bidirectional Measurement | DIN Rail Mount
Product Overview
The EM6 is a compact 6-channel energy monitoring controller designed for single-phase electrical systems.
It features a built-in BL0906 energy metering chip and an ESP32-C3 WiFi chip with 4MB flash memory. The device comes pre-installed with ESPHome firmware and supports the Bluetooth Proxy function.
With one voltage measurement channel and six independent current measurement channels, the EM6 can monitor multiple single-phase circuits at the same time. Bidirectional measurement allows the device to display both positive and negative readings, making it suitable for monitoring power consumption and reverse energy flow.
Key Features
Built-in BL0906 energy metering chip
Built-in ESP32-C3 WiFi chip
Pre-installed ESPHome firmware
Supports Bluetooth Proxy
1 voltage measurement channel
6 independent current measurement channels
Current measurement range: 0.1-97A
Supports bidirectional energy measurement
Displays positive and negative measurement data
DIN rail mounting
IPEX connector for an optional external antenna
Compact design for electrical distribution boxes

Important Compatibility Notice
This product supports single-phase electrical systems only.
It does not support three-phase electricity and must not be used as a three-phase energy meter.
Although the EM6 provides six current measurement channels, all monitored circuits must belong to a compatible single-phase electrical system.
CT Clamp Installation Warning
The current transformer clamp must be installed around only one single-phase conductor: either the Live wire (L) or the Neutral wire (N).
Do not clamp the CT around both the Live and Neutral wires at the same time. The magnetic fields may cancel each other, resulting in zero, unstable, or incorrect readings.
Correct installation:
Clamp around the L wire only; or
Clamp around the N wire only.
Incorrect installation:
Do not clamp L and N together.
Do not use the CT clamp to measure three-phase cables together.
Electrical installation should be carried out by a qualified electrician. Disconnect the power supply before installation and follow all applicable local electrical safety regulations.
Notes
Please confirm that your electrical system is single-phase before ordering.
The measurable current range is 0.1-97A.
Positive and negative values depend on current flow direction and CT clamp orientation.
An external antenna can be connected through the IPEX connector when improved wireless reception is required.
Compatibility
Designed for local smart home use with Home Assistant. Products marked as Made For ESPHome use the correct Made For ESPHome compatibility wording and are intended for ESPHome-based local control.
