Wireless Bi-directional (2-way) Electricity Energy Saving Monitor and Control System

The difference between a uni-directional (1-way) system and a bi-directional (2-way) system is that a 1-way system transmits signals only from the transmitter to the monitor while a 2-way system allows for transmission both ways.

Our wireless bi-directional (2-way) electricity power monitoring and controlling system has more functions than our uni-directional (1-way) energy monitors. It can monitor up to 14pcs sensor plug sockets and one power transmitter (supporting 3pcs sensor clamps) at the same time, moreover, the bi-directional system can also be used as a wireless remote switch for every appliance connected with the sensor socket to turn it on/off just from the controller.

Our bi-directional (2-way) electricity system can also be used for monitoring the electricity output of home solar plant and for monitoring the balance between the output and consumption. At the same time, the user can use the controller to remotely switch off some appliances if the consumption tends to be higher than the output. Details..

If the bi-directional system is still not enough for your demand or you are looking for a more powerful system for big projects or for engineering applications, then our centralized electricity management system should be your best choice.

The bi-directional system works through 433MHz wireless transmission technology together with the sensor plug sockets (working as the data collection terminal). Each monitored appliance need one sensor plug socket to act as the transmitter.

Attach the sensor plug socket first into the wall socket of power supply, then use the sensor plug sockets as the power supply for the monitored electrical appliances. All sensor plug sockets work with the controller together bi-directionally (2-way) so that the controller can receive information and send instruction from/to each sensor plug socket.

The system is simply consisted by a bi-directional controller and a number of sensor plug sockets. The number of the sensor plug socket should be decided by the quantity of the monitored electrical appliances.

As mentioned before, one bi-directional (2-way) controller can support up to 14 electrical appliances and one power transmitter. The power transmitter can be used to monitor the master outlet of the power supply. The power transmitter can support up to 3pcs sensor clamps, allowing monitoring of three-phase power supplies.

Each standard package includes 3pcs sensor plug sockets


The controller's LCD screen displays the power consuming status and the carbon dioxide correspondingly produced by the electricity consumed and forecast the electrical power cost of one hour, one day or one month for all monitored objects in summary or for one single selected monitored object, providing the user with a real time constant visual reminder of the electricity consumption and carbon footprint. This will increase awareness of energy saving and encourage the user to act to reduce the energy consumption and CO2 emission.


When the monitored electrical appliance is powered on, its corresponding button on the controller displays in pink color, so the controller can tell easily which appliances are powered on and which appliances are powered off.


With the bi-directional controller in hand, the user is able to monitor and control all connected electrical appliances in the house remotely. Just imagine switching off the oven located in the kitchen room on the first floor while you are in the bedroom on the second floor.


Cool! Amazing!

Above mentioned sensor plug socket can be replaced by our below multi-socket transmitter plug adapter.


The display screen of the bi-directional system works as below (the displayed content can be customized):

To make the date and time as well as the cost (per hour, per day and per month) to display correctly on the screen, certain settings need to be done first after the controller is powered on. You may also need to confirm with us which currencies you want to display for the cost.

The controller supports PC/MAC link with a RJ45 to USB data cable to make the user able to analyse the electricity consumption data conveniently on PC.
