MQTT energy meter: convert a SDM120 Modbus meter to MQTT
I took my earlier Modbus to MQTT project and this time modified it to work with an Eastron SDM120 Energy Meter. I am planning to use this to monitor the charging or my electric car. And also I used this opportunity to design a version 2 of my ESP8266 Modbus board. The board was manufactured by PCBWay, and you can purchase the same for yourself as well.
