Smart metering has typically depended on legacy cellular and proprietary RF protocols for its WAN needs, and Zigbee for the in-home-display (IHD) functions. But with the rise of LPWAN, the former is shifting fast, while the latter could be heavily disrupted by the adoption of Bluetooth – providing a direct link to a consumer’s smartphone, without the need for an IHD. The announcement from module vendor u-blox, in collaboration with smart metering firms Iskraemeco and EMH, caught our eye, as the trio announced a proof of concept that uses Bluetooth Low Energy as the data link to power a customer visualization application. The goal is to show customers how they are using energy, for both current and historic data, which…
