Plogg is a combined smart meter plug (kWh), load controller and data logger, designed for demand response solutions at the point of use - the appliance level. The Plogg can be configured in a number of different country plug formats and with different radio wireless devices.
Plogg is supported in a Demand Response function with the PNC, a mesh network coordinator offering a range of comms options, web server based User Interface and emulating the function of an Energy Service Portal.
Plogg Hardware
plogg can be supplied as either a stand-alone end user device, or an integrated energy reporting network or as an embedded device for incorporation into OEM products. As a plug-in device, a number of international plug formats are available including Schuko, French, Swiss, NEMA 5-15 and Australian.
The plogg use single chip single-phase meters that integrate all the primary functional blocks required of a solid state electricity meter. For OEMs interested in connecting the plogg to a Home Gateway or Smart Energy system there are a number of useful features:
- 8051 compatible microprocessor,
- Independent 32-bit digital computation engine,
- Voltage reference,
- Zigbee EM250 & EM357 wireless modules
- FRAM memory, real time clock,
- Current sensor with option of an external split core CT 100A
- 16A relay
- Plug formats, UK; Schuko, USA & Canada; France & Belgium, Australia and Switzerland
In addition to advanced measurement functions, the real time clock function allows time of use (TOU) metering information for multi-rate applications.
A 64kB FRAM memory provides fast data storage for measured values plus associated date and time stamps. The logging interval can be set from between 1 minute and 1 month.
The plogg takes 50 samples of the voltage and current signals over each cycle period.
Referenced Safety Standard: EN 61010-1:2001
Referenced EMC Standards: EN 61326-2-1:2006, EN 301 489-17 V1.2.1 (2002-08)
Certified to 
CSA C22.2 No. 61010-1
The Smart Energy Profile release of plogg has the following features:
- Telegesis ETRX3 module based upon an Ember EM357 chipset
- Platform: Ember ZNet 4.0, with ZigBee PRO feature set
- Device description: Metering Device and Demand Response Load Control

Using a ZigBee wireless network of ploggs with an ethernet host coordinator enables remote access to the network over the internet. Provided there is a local internet connection and the EAP can be installed with a static IP address then access to distributed local networks can made from anywhere in the world.
Plogg Network Controller

Software
The Plogg Manager software monitors both instantaneous and cumulative values. Logged data is downloaded in csv format to a spreadsheet or displayed in graphs:
- Cumulative kWh
- Period delta values for kWh,
- rms voltage, rms current
- max Watts, Current and Voltage
- Reactive Power
- Frequency and Phase Angle
- Logging date and time
