(under construction)

Description

This 'Energy!' node enables monitoring of AC mains power or DC power up to 15A. Additionally, this node incorporates a mains relay so that downstream devices can be shutdown or given a low-level reset.

Use this device to monitor devices and machinery to detect increased power consumption due to wear and tear. Or integrate the devices with a payment portal for metered power connections with cut-off capability upon excess current or kWh budget exceeded.

Functionality

• Measure voltage, current, power, frequency, apparent power (VA) & cos φ
• Supports bi-directional energy measurement
• Non-volatile and resettable kWh counters for both energy directions
• Programmable min/max cut-off limits for most parameters
• CANopen® fieldbus, energy measurement device profile CiA 458 + profile for generic I/O devices CiA 401
• Possibility for branding or custom firmware with specific behaviour

Network functions (via our gateway)

• Stream energy measurements via JSON
• View power levels directly via HTML, no cloud needed
• Logging to micro-SD card
• Node ID assigned via serial number
• Remote configuration & firmware update
