Hi, thank you very much for the question. I can collect data from the SMA inverter. Thank you really much for the work, that’s amazing!
I was working on integrating my energy meter using the infrared interface that send information to MQTT. My “week-end” work is on https://github.com/gabrielklein/EnergyMeterIEC62056. I have a small raspberry that collect this information. I share this information because other people may be interested by this ~50€ project that give information concerning your power consumption, voltage, power factor and it’s not far from this project…
I’ll come back to the SMA part as soon as I can process the information I receive from my energy meter using MQTT.
What would be funny is to provide a modbus interface on my “energy meter raspberry” as I saw a few server in java… but it’s another project.
