u-blox collaborates with Iskraemeco and EMH to integrate Bluetooth display interface for smart meters

u-blox, a global provider of leading positioning and wireless communication technologies, is developing a way to make it easier for utility customers to track and visualize their energy consumption. The proof of concept (PoC) design is the result of a three-way collaboration between u-blox and metering companies Iskraemeco and EMH.

The PoC design uses a Bluetooth low energy (BLE) interface to connect a smart meter to a consumer’s smartphone or tablet. The mobile device can then provide a more detailed visualization of current and historical energy consumption than is possible on the simple displays used in smart meters.

The PoC has been developed as a response to utilities that require smart meters to offer users a simple and efficient way of visualizing their consumption of electricity, including their historical usage, without using any additional equipment. The existing displays used on electricity meters are not optimal for this sort of visualization.

“We expect that demonstrating the PoC will result in BLE being established as the interface required in all future smart meters,” says Stefan Berggren, Senior Product Marketing Manager, Product Center Short Range Radio, u-blox. “The inclusion of a Bluetooth low energy interface will also make it possible for smart meters to connect into a local Smart Home environment that could enable value-added services, such as temperature and humidity monitoring for customer locations and second homes,” he adds.

BLE’s support for mesh networking will also make it possible to extend the range of the smart meter’s connectivity through intermediate devices, such as installed sensors, so that users can query their utility consumption information when they are beyond the usual range of a BLE connection.

To address current concerns about data privacy and security, the PoC uses a secure BLE module from u-blox, which has been designed to industrial standards. Close collaboration with Iskraemeco and EMH facilitated consideration of particular design requirements and security challenges of the metering business.

The PoC will be demonstrated at European Utility Week in Vienna, Austria, from 6th to 8th November.
