An IoT Current Monitoring Service using the Cloud.
EnergyGazer is a cloud-based IoT current monitoring system that retrofits to existing distribution boards. It monitors up to 16 circuits at 3-second intervals, with PoE power and Web API support.
Because there is no need to replace the distribution board or carry out major modifications, installation costs are kept low.

Connect the clamp sensors to the EnergyGazer device and connect it to the Internet.
After registering an account and completing the setup, you can start using the service.
* An on-premises version is scheduled for release in the future.
Supports Large-Scale System Deployment
This system enables centralized monitoring of current usage at headquarters across multiple locations nationwide, while also allowing real-time monitoring at each individual site.
Example Use Cases
- Centralized power monitoring for large organizations
- Power monitoring at unmanned sites
- Effectiveness measurement during equipment upgrades
- Monitoring as a countermeasure against internal breaker trips
- Evaluation of equipment deterioration caused by abnormal current levels
- Power interruption detection for devices requiring constant power supply
Features and Functions
User Interface
- Displays current usage status and total values in easy-to-understand graphs.
- Measurement interval is 3 seconds, allowing you to quickly check the latest current value.
- Measurement data is stored for up to two years, enabling long-term trend analysis (such as seasonal variations).
- Past data can be compared for analysis.
- Graphs allow zooming in on specified past points, making it possible to compare, for example, the same date and time one year ago.
- Accessible via a web browser and supports multiple devices.
- Upper and lower threshold values can be configured for monitoring. A notification is sent when a configured threshold is exceeded.
- Notifications are delivered by email and Slack.
Other Features
The unit supports both AC adapter power and PoE power supply.
Measured data can also be provided via a Web API, allowing it to be integrated and used within your own systems.
