ESPHome EU Dual Smart Plug with ESP32-C3, Bluetooth Proxy and Independent Energy Monitoring
Two Independently Controlled Outlets in One Smart Plug
Upgrade two ordinary appliances with local smart control and real-time electricity monitoring.
This EU dual smart plug features an ESP32-C3 Wi-Fi chip, pre-installed ESPHome firmware, Bluetooth proxy enabled by default, a BL0939 dual-channel energy metering chip and a built-in 16A relay switching system.
Both outlets can be controlled and monitored independently through Home Assistant, while the maximum combined current of the entire plug is 16A.

Independent Energy Monitoring
The built-in BL0939 metering chip supports dual-channel electricity monitoring.
View the following information in Home Assistant:
Supply voltage
Individual outlet current
Individual outlet active power
Individual outlet energy consumption
Combined operating information
Independent measurements make it easier to compare appliance consumption, identify standby power and create automations based on real power usage.
Power-Based Automations
Energy data can be used to create practical Home Assistant automations, such as:
Notify when an appliance has finished operating
Turn off a device when its power drops below a selected level
Detect whether an appliance is running
Track daily or monthly energy consumption
Automatically disconnect standby devices
Alert when power consumption exceeds a configured value
ESPHome Pre-Installed
The plug arrives with ESPHome firmware already installed and integrates with Home Assistant through the native ESPHome API.
ESPHome provides:
Fast local control
Real-time status updates
Custom automations
Configurable entities
Wireless OTA updates
No mandatory manufacturer cloud service
Flexible firmware customization
Bluetooth Proxy Enabled by Default
The default firmware includes ESPHome Bluetooth proxy support.
The ESP32-C3 can forward data from supported nearby Bluetooth Low Energy devices to Home Assistant through the Wi-Fi network, helping extend Bluetooth coverage around your home.
Supported device types may include:
Bluetooth temperature and humidity sensors
Door and window sensors
Plant sensors
BLE buttons
Bluetooth beacons
Other Home Assistant-compatible BLE devices
Bluetooth performance depends on device placement, surrounding walls, interference and Home Assistant configuration.

Important Information
The maximum current is 16A combined across both outlets.
Each outlet is not rated for 16A at the same time.
The total connected load must not exceed the product’s maximum rating.
Actual safe load depends on appliance type, inrush current, operating temperature and local electrical regulations.
Use an appropriate safety margin for high-power, inductive, motor-driven or continuously operating loads.
A 2.4GHz Wi-Fi network is required.
Initial Wi-Fi configuration is required before use.
Advanced customization requires basic ESPHome knowledge.
