F&F LE-03MQ Modbus energy counter

[buuuudzik]

I try read properly L1 voltage which should be ~230V. In the manual there is the information that every value is hold in 2 x float16 registers so I've tried such json definition:
{ "address": 0, "read_count": 2, "name": "Napięcie fazowe L1", "bus_datatype": "float32", "type": "register", "datatype": "float16", "units": "V", "writable": false }

And the result is 1597.440V so there is some bad in my definition.
