MODBUS data from SMA Inverter

[chris_ka]

Yes modbus is definitely broken in 0.108 1-3
I stay on 0.108.3 but I switched to NodeRed and MQTT to retrieve my modbus data.
everything works now again.

I wrote a tutorial how to do this:

Tutorial to read Modbus Registers in NodeRed and sent to MQTT

Interesting and thanks for the tutorial. What’s the reason behind making a single MODBUS call to retrieve 30513-30520 which equates to 2 registers? What about retrieve of each value separately and end up with a much simpler JavaScript block?
