An adapted version of the ProMini LoRaWAN Node, to connect to a GC90/91 DC power meter and transmit its readings via LoRaWAN. A short overview of the used hardware and features:
- Arduino Pro Mini (Atmega328, 8Mhz, 3.3V)
- RFM95 LoRa Module
- Levelshifter and USB connector to interface with the GC9x series power meters
- u.FL antenna connector
- Grove connector for I2C (can also be used for analog or digital signals)
- Circuitry to measure input voltage
- Add firmware to repository
- Put kit on Tindie
- Test/Support other GC9x series meters
- Replace power meter completely, take measurements ourself (e.g. DIY Arduino Multifunction Energy Meter
