Hello,

the frequency is displayed incorrectly.

name: Grid Frequency slave: !secret sungrow_modbus_slave address: 5035 # reg 5036 input_type: input count: 1 data_type: uint16 swap: word precision: 2 unit_of_measurement: "Hz" device_class: frequency state_class: measurement scale: 0.1 -> scale: 0.01 scan_interval: 10

I found the solution. It's the Ethernet interface.

I now use the ETH port, directly on the inverter. (not via WiNet-S)

Now the values all match.

Thanks
