The MEMo web server is an advanced data logger for measuring and controlling total and sub-consumption in a home or building.
A 2-Wire MEMo system consists of a central MEMo datalogger web server that communicates wired (RS485 MODbus) and / or wireless (LORA and FSK 868MHz) with, among others, Modbus energy meters.
Up to 64 energy meters (depending on the number of channels per meter) can be connected to one MEMO. Every 60 seconds counter readings and measured values are read out and stored in raw format for up to 3 years.
MEMo is connected to the local network via its LAN port and can be used to map all the consumption and energy costs of the building.
The read-in counter readings can also be used for settlement of mutual energy costs.
In addition, MEMo can be set up to periodically upload meter readings (FTP client) to a remote server in order to centrally manage several buildings and compare them to mutual energy performances.
The system below consists of a MEMo server, a number of wired Modbus energy meters, an RF gateway for linking gas and gas meters, a connection to the digital meter and a few energy plugs for reading household appliances …
From the web browser on every tablet or PC, you can surf to the website in the MEMo module to configure the system, visualize the energy consumption and costs, and switch consumers on or off. Consumption charts can be set with a resolution of 1 minute to 1 day, energy costs are calculated on the basis of adjustable energy unit prices.
Internal Web server shows per energy channel:
FTP client: CSV files with adjustable interval periodically loaded to a remote server
Http instruction set: the internal “raw” database is easily accessible for external applications
5 Users simultaneously, each with their own login and password
Time synchronization with external NTP server
Adjustable energy prices
Auto Backup on internal 4GB SD card
SUB totals: calculation of meter readings, consumptions and costs for a set period, with built-in filter and export to Excel, JSON, CSV, PDF, print
Email notification: adjustable consumption / daily consumption / temperature limits
Calculation EPC (energy efficiency of the building) on the basis of measured consumption
Top 10 of the most expensive users
Calculation overview all consumers
Firmware update via FTP
Built-in visual logic user interface offer almost unlimited possibilities: (starting from MEMo2)
The 2-wire modules are installed by the electrician in the fuse box and then the server is connected to the local network.
Through the webservers web pages, the names of consumers, consumption units, energy prices, network setting, ... can easily be configured via tablet or PC.
After the configuration every minute all measured data is read and stored in the web server. All consumption values and energy costs are now accessible via Web browser.
For software developers: 2-WIRE development pack
Download data log files or get them sent periodically, visualization and control from your own application,...
The development pack will explain how this can be done easily. The pak may be obtained free of charge by anyone which owns a 2-Wire Web server.
