# MODBridge-and-Blynk

This is a working example of open source MODBridge working with the SDM120 Energy meter via MODBUS RTU.





 

MODBridge can be find at: untrol.io and Tindie



SDM120 Energy meter: SDM120 Modbus RS485 Single Phase DIN Rail Energy Meter



SDM220 Energy meter: SDM220-Modbus Single Phase DIN Rail Energy meter, RS485 Modbus



SDM630 Energy meter: SDM630-Modbus  Din Rail Three Phase Energy Meter. RS485



Programming dongle for UART/USB if not, OTA: USB to serial UART Programming





The firmware has been writen using PlatformIO which is a nie, neat IDE, check it out: Learn how to install PlatformIO IDE

If you're feeling brave and want to customize or improve the Firmware Over the Air (OTA), check this link: Over-the-Air (OTA) update basically you change your sketch and upload it by running the following line on PlatformIO terminal:



platformio run --target upload --upload-port IP_ADDRESS_HERE



OR if you want to use Arduino IDE: Arduino IDE OTA
