Published On: January 28th, 2025463 words2.4 min read

With the growing digitization and interconnectivity of devices, wireless communication is becoming increasingly important in measurement and control technology. This article explores the development of an innovative LoRaWAN add-on for the Smarty Meter that efficiently transmits the device’s relay states wirelessly.

The Smarty Meter is a widely used and flexible electricity meter deployed in both industrial and residential settings. Many applications require monitoring and controlling the two built-in relay states. A key use case is the legally mandated control of inverters and electric vehicles on behalf of electricity providers. The challenge has been to transmit this information at regular intervals to central systems without relying on wired communication methods.

LoRaWAN (Long Range Wide Area Network) offers an ideal solution. It is a wireless communication protocol designed for low energy consumption, long range, and high efficiency—perfectly suited for IoT (Internet of Things) applications.

  • Compatibility with the Smarty Meter – The add-on is connected directly to the Smarty Meter and capture its relay states.

  • Regular Transmission – Relay states are transmitted at a fixed interval complying to energy provider’s specifications.

  • Robust Communication – The system ensures stable transmissions by automatically closing the relay in the event of signal disruptions.
  • The strenghts of LoRa – Offers greater range and better wall penetration compared to WiFi and Bluetooth.

  • Easy Installation – The adapter has only to be paired with its designated sender, eliminating the need for complex configurations or installations.

The development of a LoRaWAN add-on for the Smarty Meter marks a significant step toward smarter energy solutions. With this add-on, the meter’s relay states can be transmitted simply and efficiently—a critical advantage for numerous applications in modern energy and building technology.
