Smart Energy & Hour Monitoring IoT Device | Single-Phase

The Smart Energy Monitoring IoT Sensor is a cost-effective solution for monitoring single-phase machines, appliances, and equipment. Designed for SMEs, workshops, and smart home/office applications, this device provides accurate energy insights without the high cost of industrial-grade hardware.
It supports multiple communication protocols, including HTTP, MQTT, and Modbus TCP, making it simple to integrate with existing cloud dashboards, IoT platforms, or lightweight monitoring apps.
In addition to core energy parameters, the sensor also provides runtime monitoring and idle time tracking, enabling businesses to optimize usage, cut unnecessary energy waste, and perform proactive maintenance.

Key Features:

• Voltage & Current Monitoring – Accurate readings for supply and load.
• Active Power & Energy Tracking – Continuous measurement in W and kWh.
• Power Factor & Frequency Monitoring – Detect inefficiencies and supply issues.
• Runtime Monitoring – Automatically log how long machines run each day.
• Idle Time Detection – Spot energy waste during no-load operation.
• Connectivity Options – Supports HTTP, MQTT, and Modbus TCP for flexible integration.
• Compact, Affordable Design – Ideal for small industries, workshops, and smart home projects.
• Easy Installation – Plug-and-play setup without industrial infrastructure.
