Providing consumers with real-time information on energy consumption can help improve awareness and promote more energy-conscious behaviors, good for reducing electricity bills and, globally, carbon emissions. Smart plugs, an energy measurement and control system connected to the home area network (HAN) and to mobile devices including smartphones, can help with this.

We have a complete offer of high-accuracy energy metering ICs and high-performance STM32 microcontrollers as well as buck or flyback AC-DC converters, BLE and 802.15.4 Thread and wM-Bus wireless connectivity and narrow-band power line communication solutions.

In addition we can help developers reduce time to market with a comprehensive set of hardware and software evaluation and development tools and reference designs.
