With the energy monitors LoWi3 or ReMI for homes, and Memo3 for buildings, in addition to energy consumption and energy cost, the current quarter power and highest monthly peak from the Belgian digital meter or from the 2-WIRE energy meters are read in and displayed on any device with a web browser within the (home) network.

But grid voltage, important for people with failing solar panels, and actual power per phase, to enable smart switching with ReMI or MEMo3, are also monitored along with time.


LeON and THEo

Each of these USB energy sticks with RGB LED give you instant insight into the current energy rate. With a quick glance at the color, you can see whether the day or night rate applies (RED/BLUE) and whether energy is injected (GREEN). But that’s not all!

The flashing speed of the LEDs indicates how much energy you are consuming or injecting. That way you know whether you can start the dishwasher or dryer on solar power (green), or whether it’s better to wait a bit during peak consumption (red).

THEo goes one step further and also measures room temperature and humidity. This data is then displayed live and historically on the linked web server(s). This allows you to understand the climatic conditions in your living space and adjust to optimal comfort.




MEMo3 shows the ‘proper’ operation of each building



Connect a Memo3 data logger web server via Modbus, wirelessly over RF or over Internet/IoT to the various energy meters in one or more buildings.
Surf to the MEMo3 IP address, give all meters a Modbus address and a name after which MEMo records meter readings every minute and stores them locally for up to 3 years.

Current readings, histories, energy costs are now accessible locally via web browser to anyone within the network, or remotely via the html app.

MEMo runs with no software, no subscription fees and completely separate from existing technologies. After only a few days of logging, one gets detailed visibility into the good or bad performance of the building and its larger consumers.

In addition to monitoring, there is also the ability to intelligently control certain large consumers, or to bill for energy costs over a set period of time based on meter readings.

Energy monitoring creates a great opportunity for the smart installer, easy monitoring can now be done in any building, new or existing.


Energy meters

The autonomous kWh meters are read every minute and provide insights on current and historical consumption over long periods of time. But calorimeters, Co2 meters, pulse counters, Fluvius meters, … are also read by MEMO3.



Why a Web server and not an app or cloud application?
