Centralized management of multi-site power! Energy monitoring unit.
Centralized management of energy data from multiple remote locations such as stores, factories, and facilities in the cloud.
Easily monitor remote power and energy with LTE-M communication! The LTE-M compatible energy measurement unit "WLM" series is an IoT measurement unit suitable for monitoring power and energy at multiple locations spread over a wide area, as well as equipment and devices scattered in the field. The measured data is sent to the cloud via LTE-M communication, allowing for remote monitoring that replaces the manual measurement and verification tasks previously done on-site, enabling centralized management of power usage across multiple locations. ■ Send measurement data to the cloud via LTE-M communication ■ Supports approximately 5 years of battery operation * ■ Can be installed in locations where power wiring is difficult ■ Supports remote monitoring of multiple locations and scattered equipment ■ Body settings can be configured from the cloud ■ Supports remote monitoring via alarm emails ■ Can be used in conjunction with an AC adapter
