Introducing the ENMAT Modbus Bridge


pdf_icon Datasheet

Product Description

The ENMAT Modbus Bridge is designed to connect one or more modbus slave devices (e.g. Modbus Smart Meter) with RS485 to the ENMAT Wireless Data Logger wirelessly.

The ENMAT Wireless Data Logger connected to the Gateway can communicate with Modbus slave devices eliminating any hard wired installation. This communication link is completely transparent. Furthermore it can be a repeater and a parent device for battery powered sensors.

Wireless range 30-100 meters depending on building fabrication and line of sight.

Introducing the ENMAT Portable Data Logger

ENMAT Portable Data Logger

pdf_icon  Datasheet


Product Description

The ENMAT Portable Data Logger combines the ENMAT Lite Data Logger and a ENMAT 3 phase Smart Meter to provide an all-in-one monitoring solution.
The ENMAT Portable Data Logger comes with split core CT clamps (0.333VAC) which can be installed without any supply disruption as the clamps cannot produce dangerously high voltages at the output.

Real power can be recorded by connecting to the voltage taps to measure consumption (kWh) and reactive power (kVArh).
Equipped with a battery backed clock that automatically updates the time from the internet, the built-inENMAT Lite Data Logger ensures energy consumption data is accurately recorded.

The ENMAT Portable Data Logger is ideal for sites that have not yet sub-metered and wish to gain an understanding of energy usage across the site.

The ENMAT Portable Data Logger is the first step to enable Energy Managers to monitor energy before permanent metering is undertaken.
Data can be recorded automatically into the built-in ENMAT Lite Data Logger. From here the data can be auto emailed through the ENMAT Portable Data Logger’s Ethernet connection to the internet.
Where no internet connection is available a GSM modem can be connected.
Alternatively record data for a period of time and send the unit back to Envantage ENMAT where we can upload the data to the ENMAT Cloud Software.

ENMAT Wireless Meter


pdf_icon Datasheet

The ENMAT Wireless Meter allows Energy Managers to monitor electricity consumption wirelessly, without the need for expensive metering solutions or comprehensive cabling.

The ENMAT Wireless Meter clamps around the electrical circuit and transmits wirelessly consumption.

Wireless communication significantly reduces time, cost and disruption involved in deploying sub-metering installations.

Energy Consumption data is automatically logged with the ENMAT Premium Data Logger or ENMAT Wireless Data Logger. Logged data is then transmitted from the logger to ENMAT Cloud Software.

Introducing the ENMAT Wireless Data Logger


pdf_icon Datasheet


The ENMAT Wireless Data logger is ideal for small, medium and large buildings that require the centralisation of energy related data.

The unit comes with built in Ethernet and GSM/GPRS modem to suit various installation requirements.

The data logger is capable of sending energy related data to ENMAT Cloud based software via a CSV file.

This user friendly system allows for an easy setup and configuration. This means solutions can be rapidly Installed, without major disruption to the site.

The ENMAT Wireless Data Logger has Modbus for communication with additional meters and sensors, making it the most versatile energy logger on the market.

Energy consumption is recorded at selectable intervals, typically ½ hourly.

This data is stored on the ENMAT Data Logger and automatically sent to the ENMAT Cloud Server.

Tenant Billing Software

Tenant Billing SoftwareENMAT’s Tenant Billing Software provides organisations with the ability to accurately divide utility costs between tenants.

ENMAT can create individual tariff rates per tenant based on sub metering to each tenant.

ENMAT can define landlord and or supplier tariff rates separately. The ENMAT Document Library facility allows Landlords to store Energy Invoices to tenants.

NHH (Non Half Hourly) 05-08 metering – Licence Conditions with guidance notes for the provision of advanced metering for larger business sites



In April 2009 the government introduced a requirement for Suppliers to provide advanced metering for larger non-half-hourly read electricity and non-daily read gas sites in the non-domestic sector. For electricity this affects about 170,000 sites in Profile Classes 5 to 8. The requirement applies to new and replacement meters, with advanced metering to be installed for all such sites by 06 April 2014.

ENMAT provides replacement metering solutions for customers still using profile classes 5 to 8.  Contact ENMAT today to discuss your needs.

For the DECC AMR documentation please click here. 



 In Summary:


  • Licence Conditions for the provision of advanced metering for larger business sites


  • Came into force April 2009


  • Obligation on all electricity and gas suppliers to install AMR by 5/4/2014


  • Applies to non-domestic supplies


  • Electricity profile classes 05 to 08


  • Gas sites with a measured annual consumption ≥ 732,000 kWh


  • Applies to all new supplies, any replacement meter and to all relevant supplies after 5th April 2014


  • In effect, from 2014 onwards suppliers can only use Advanced Metering on these larger non-domestic supplies


Profile Class (PC)

The first two digits of a full MPAN reflect its profile class

00 Half-hourly supply (import and export)
01 Domestic Unrestricted
02 Domestic Economy 7
03 Non-Domestic Unrestricted
04 Non-Domestic Economy 7
05 Non-domestic, with MD recording capability and with LF less than or equal to 20%
06 Non-domestic, with MD recording capability and with LF less than or equal to 30% and greater than 20%
07 Non-domestic, with MD recording capability and with LF less than or equal to 40% and greater than 30%
08 Non-domestic, with MD recording capability and with LF greater than 40% (also all NHH export MSIDs)


What is a Non-half-hourly metered supply?

For non-half-hourly metered supplies, the NHHDC determines the consumption by calculating the advance (the difference between the last two meter reads, this is annualised to produce an annual advance (AA), this being the data the supplier will pay on).

The NHHDC is also responsible determining the estimated annual consumption (EAC), which is a forecast for a year ahead. The EAC is initially provided by the supplier, and thereafter forecast based on actual meter readings.

Data from the DC (EAC/ AA’s) is provided to the non half hourly data aggregator, which aggregates the individual values provided into a single figure split in a number of ways e.g. geographically, geographically & supplier or supplier. This aggregated data is then provided to the Central Systems, maintained by Elexon, to determine the value of energy which has been used by suppliers so that they are able to settle with the distribution network which generated the energy. The process is known as balancing and settlement and falls under the balancing and settlement code (BSC).
