Modbus Profil/Bool values? - Stieges - 02.01.2024
Hey guys,
I try to read the values from my Sungrow Inverter. When i try to read values with the "Read Check" I get good values. After that I made the profil for the device, added it and it seems that i only get boolean values but i don't know what to change.
My Profil:
Code:
{
"manufacturer": "Sungrow",
"description": "SH10RT Inverter",
"mapping": [
{
"name": "NominalOutputPower",
"bus_datatype": 1,
"datatype": "uint16",
"type": "inputregister",
"address": 5000,
"units": "kW",
"value_multiplier":0.1
},
{
"name": "Daily Output Energy (PV+BAT)",
"bus_datatype": 1,
"datatype": "uint16",
"type": "inputregister",
"address": 5002,
"units": "kWh",
"value_multiplier":0.1
},
{
"name": "Total Output Energy (PV+BAT)",
"bus_datatype": 1,
"datatype": "uint32",
"type": "inputregister",
"address": 5003,
"units": "kWh",
"value_multiplier":0.1
},
{
"name": "Inside Temperature",
"bus_datatype": 1,
"datatype": "uint16",
"type": "inputregister",
"address": 5007,
"units": "°C"
},
{
"name": "MPPT 1 Voltage",
"bus_datatype": 1,
"datatype": "uint16",
"type": "inputregister",
"address": 5010,
"units": "V",
"value_multiplier":0.1
},
{
"name": "MPPT 1 Current",
"bus_datatype": 1,
"datatype": "uint16",
"type": "inputregister",
"address": 5011,
"units": "A",
"value_multiplier":0.1
}
]
}Can somebody help me please. And yes I am very new to this whole topic

You did set "bus_datatype": 1, this is a boolean change to "float16"
RE: Modbus Profil/Bool values? - Stieges - 02.01.2024
You mean "bus_datatype": float16
RE: Modbus Profil/Bool values? - Daniel - 02.01.2024
"bus_datatype": "float16",

Thank you. Worked out fine after updating the firmware of the modbus device.
