Smart electricity cost meter GreenBlue GB350E for monitoring power consumption and cost

GreenBlue GB350E is an electricity cost meter designed to monitor power consumption and calculate energy costs for connected devices. The device measures voltage, current, instantaneous power and cumulative energy use in real time, presenting values on a built-in display to help identify high-consumption appliances and estimate running costs. Intended for home or small-office environments, the GreenBlue GB350E provides continuous monitoring to support energy-aware decisions and basic cost tracking.

Advantages

The meter provides real-time measurement of electrical parameters and translates consumption into monetary cost using a user-set tariff, enabling straightforward assessment of appliance expenses. Its integrated display offers clear numeric readouts of power, energy and cost without the need for external software. Compact form factor and simple connection make it suitable for placement between wall outlet and device, while the unit’s data update rate allows timely detection of changes in load.

Suitable for

• Monitoring individual household appliances such as refrigerators, heaters, washing machines and TVs
• Tracking power use of office equipment including printers, computers and network devices
• Estimating running costs for devices with variable usage patterns
• Identifying standby power drains and appliances with high idle consumption

Key specifications

• Measurement functions: voltage, current, instantaneous power, cumulative energy
• Cost calculation: user-configurable energy tariff to display monetary consumption
• Display: built-in digital screen for real-time numeric readouts
• Installation: inline between mains socket and appliance for direct measurement
• Target use: designed for residential and small-office power monitoring

How to use

Plug the GreenBlue GB350E into a standard mains socket and connect the appliance to the meter’s outlet. Set the local electricity tariff on the unit to enable cost calculations. The display will show voltage, current, instantaneous power and accumulated energy; monitor these readings to assess consumption patterns. For accurate cost reports, ensure the tariff is updated if your billing rate changes and allow the meter to accumulate energy data over the period you wish to evaluate.

Usage recommendations

Use the meter on individual devices rather than whole-home panels to obtain device-level consumption. For comparison of appliances, measure each item over similar operating periods and with typical usage settings. Avoid exposing the unit to moisture or extreme temperatures and follow basic safety practices for mains-connected equipment.
