The new firmware version 17.10.8.1 for the 2-Wire MEMO data logger / web server is online, via the setup you can update the 2-wire MEMo web server and the connected measurement modules for free.
In this YouTube tutorial you will see how this can be done.

What’s New?

60 seconds resolution in 24hr graphs:

 

Memo records every 60 seconds metervalue (import + export) and a number of measured values (voltage, current, power, …) of all connected meters and stores this data locally for 3 years.
From the new firmware you can zoom in on the 24hr charts to a resolution of 1 minute and that up to 12 days back in time. Besides consumption and energy costs, it is now possible to analyze easy errors, peaks in consumption-voltage-temperature flow rates … in the installation.
Useful in any electrical or HVAC installation.

FTP client functionality to Comeet (EANDIS) and EnergyID:

Meter positions and measured values are kept for up to 3 years in the MEMo module. MEMo can prefilter these raw data and periodically load to an external server application.
For example, we were asked a few times to upload measurement data to Comeet, the Eandis application for energy management in public buildings, and we received a similar question to charge metrics to EnergieID, a public platform where consumption in homes can be shown and compared to other homes.
With the current firmware version, the csv files generated by MEMo can be read seamlessly by both external applications.

Coupling to MODbus Water Meters and MODbus Calorimeters:

Until today, water meters and calorimeters could only be linked via the pulse counter module. With the new firmware, these meters can now be read through MODbus. You will find the relevant meters on our website. Both meters are measuring consumption but besides that also flow rates and water temperatures are continuously measured, logged and then displayed in the web server graphs.
For billing purposes, these meter positions can be retrieved from the web server for a set period of up to 3 years.

Reset log data per channel or per module

From this firmware you can easily empty 1 individual measurement channel on a PC.080 or EC.441 module or reset all log channels to a module or bring the complete database to factory settings, how to read this in our FAQ or in the manual of the MEMo server.

Maximum power / power:

MEMo records meter readings and measured values ​​as 32 bit values, so no restrictions in the logs, however, the graphs in the web server had a limit of consumption up to 32 kWh and we have now eliminated this limitation.
For measuring larger consumers we also make use of Rogowski coils coupled to our new EMM.630 MV CT energy meter.

Adding new RF gateway module:

The RF Gateway is a new module that will be available by the end of this year. This module connects to the Dutch smart meter as well as to wireless 868MHz “energy plugs” in order to measure and switch the consumption of individual household appliances.
