Turn your Raspberry Pi into a smart meter
With SmartPi 3.0, the power consumption data can be conveniently
SmartPi 3.0 measures all important data:
- Active power
- Reactive power
- Apparent power
- Energy consumption
- Energy production
- Power consumption
- Power production
- Cos Phi
Web interface, database, MQTT, REST and node-red control
Open Source Smart Meter 3.0
Ideal to use SmartPi in your own projects or to extend the range of functions.
Examples that can be built with the SmartPi:
- Energy monitor via network and Internet
- Mains frequency monitoring
- Mains voltage monitoring
- Alarms at power consumers
- Alarms for increased consumption
- Integration into energy management systems
- Cost control
All interfaces to the Raspberry Pi are galvanically isolated and ensure
- Reads current, voltage, power and many other data every second.
- Store values in the database every minute
- MQTT support
- Prometheus support (not yet documented)
- Node-Red Integration
- CSV FTP upload
- Web interface for display and configuration
- UMTS support
- Raspberry Pi compatible connector
- Raspberry Pi compatible size
- Galvanic isolation
- Integrated power supply from the voltage measuring path
- via stable terminals (optionally 2A DC current)
- Open source drivers and API
- Current measurement on 3-phase
- Connection for cable converter with a secondary output of 50mA and 1A
- Screw terminals for connecting the current and voltage measurement
- Compatibility with all Raspberry Pi models
- buffered RTC (the Raspberry Pi continues to run stably)
- even without an Internet connection after a power failure)
- Additional status LED
- High-quality housing with top-hat rail mounting
