SmartPi 3.0 - Turn your Raspberry Pi into a smart meterThe Smart Pi expansion module extends the Raspberry Pi with interfaces to measure voltage and current in a contactless manner. It enables to control electricity production consumption and turns the Raspberry Pi into a full featured smart meter. All measurement data can be stored and are accessable via the local network or Internet for disposal.Current is measured contactless via inductive current sensors. In the standard version currents up to 100 A can be measured. A simple changeover of the jumper enables the connection of any cable re-converter with a secondary current of 1A. This allows currents of up to 1000A and more to be detected.The SmartPi 3.0 has 3 inputs for current measurement (L1, L2, L3) and three inputs for voltage measurement. This allows measurements on all three phases and even the neutral conductor. The SmartPi 3.0 and the Raspberry Pi can be powered by the voltage input. An external power supply is not required.If the voltage measurement is connected, the direction of the energy flow can be determined and the SmartPi is a full-fledged bi-directional smart meter.. Other units:CurrentVoltagePowerActive powerReactive powerApparent powerEnergy consumptionEnergy generationPower consumptionPower generationPower frequencyCos phi The interfaces to the Raspberry Pi are electrically isolated to ensure maximum safety.Website and REST interfaceOpen Source software is written in Go and includes all the necessary drivers, a web server with web page and a REST interface.All measurement data can be logged and displayed on tablet or smartphone.

SmartPi 3.0 board - turn your Raspberry Pi into a smart meter The SmartPi expansion module adds voltage measurement and contactless current measurement to the Raspberry Pi (3 B, 3 B+, 4), turning it into a full smart meter that monitors and records electricity consumption and generation and makes the data available on the network or the internet. Current is measured contactlessly via current clamps for currents up to 100 A or 400 A in the standard version.By simply moving a jumper, any cable-conversion transformer with a secondary current of 1 A can be connected, so currents of 100 A and more can be measured. The SmartPi 3.0 has 3 current inputs (L1, L2, L3) and three voltage inputs. The voltage input can also power the SmartPi 3.0 and the Raspberry Pi, so no external power supply is needed. With the voltage measurement connected, the direction of energy flow can be determined and the SmartPi becomes a full bidirectional smart meter.   Further values: Currents Voltages Power Active power Reactive power Apparent power Energy drawn from the grid Energy fed into the grid Power drawn from the grid Power fed into the grid Grid frequency Cos phi The interfaces to the Raspberry Pi are galvanically isolated for maximum safety. Scope of delivery: 1x SmartPi 3.0 board 1x ribbon cable 4x spacers 8x screws 3x jumpers 1x 6-pin plug 2x 2-pin plugs Website and REST interface The open-source software, written in Go, includes all necessary drivers, a web server with web interface and a REST interface. The measurement data can be logged and displayed on a mobile phone or smartphone. Via the REST interface, the SmartPi can be integrated into your own applications and apps. Examples of what you can build with the SmartPi: Energy monitor via network and internet Grid frequency monitoring Grid voltage monitoring Alarms for electrical loads Alarms for increased consumption Integration into energy management systems Cost monitoring Software features: Reads current, voltage, power and many other values every second Stores the values in the database every minute MQTT support Prometheus support (not yet documented) CSV FTP upload Web interface for display and configuration UMTS support Features/specifications: Raspberry Pi compatible connector Raspberry Pi compatible size Galvanic isolation Integrated power supply from the voltage measurement path via sturdy terminals (2 A DC current) Open-source drivers and API 3-phase current measurement Connection for cable-conversion transformers with a secondary output of 50 mA, 333 mV and 1 A Screw terminals for connecting current and voltage measurement Compatible with all Raspberry Pi models Buffered RTC (the Raspberry Pi keeps running reliably after a power failure, even without an internet connection) High-quality housing with DIN rail mounting (Raspberry Pi 3 B only) E1 expansion: RJ12 6P6C: 1: 5V, 2: GND, 3: GPIO23, 4: GPIO24,  5: SDA (GPIO 2), 6 SCL (GPIO 3) E2 expansion: RJ10 4P4C: 1: MOSI (GPIO 10), 2: MISO (GPIO 9), 3: SCLK (GPIO 11), 4: CE1 (GPIO 7)  Cloud: Free beta cloud: https://beta.smartpi.eu Cloud connection via MQTT Display of current measured values Graphical display of the last 5 minutes   Customs tariff number: 90283019
