Energy monitoring with LoRaWAN

30 March 2022

Semtech Corp. is collaborating with Vutility, an energy monitoring vendor, to connect long range (LoRa) devices and long-range wide area networks (LoRaWAN) to the company’s HotDrop real-time energy monitoring solutions.

Using the LoRaWAN standard, HotDrop provides real-time, circuit-level energy monitoring of a facility that can help to lower electricity costs. The solution is self-powered, non-intrusive and battery- and maintenance-free.

HotDrop is designed as an instantaneous install without requiring the facility to de-energize with a simple QR code scan for onboarding through an Android or iOS device and a wireless clip closure around the monitored circuit.

Combined with LoRa devices and LoRaWAN, it serves as the internet of things (IoT) backbone of the energy monitoring system via application programming interface (API) to any end application. The minute-by-minute relay of data benefits users to monitor their electricity usage in real-time, potentially saving energy costs.

“A key challenge we faced when developing the HotDrop solution was to identify a wireless IoT standard that was able to communicate out from inside an electrical distribution panel, with similar radio-frequency disruptions to a Faraday cage, and through multiple dense walls and floors of buildings,” said Micheal Austin, CTO at Vutility. "The long-range transmission capability of LoRaWAN was able to meet and even exceed expectations for ‘HotDrop’ to maintain wireless, real-time transmission signals to the Cloud. Leveraging LoRaWAN was ideal for us to scale the ‘HotDrop’ solution.”
