Can you tell me the version of the integration you're using? How many panel strings do you have connected, 1 or 2? Also, can you show me the screenshot of qmodmaster with offset 122? The problem is that for some inverter models, the M160 sunspec model doesn't start at 122, so we need to find where it is in your case. For UNO-DM-* and REACT2-* models, the offset is 1104. If we can find where the M160 model starts, I can implement a fix for your model. You need to use qmodmaster to find it. |

can you set 70 as start adress (offset)? the first register should be 101 or 103. You have base address set to 1 and Little Endian configured (see the bottom status bar of qmodmaster):
configure qmodmaster settings like this (big endian):
Also, click the grid icon to show the column/row offsets, at start address 70 you should see this:
first register you should see 101 or 103: 101 means monophase inverter and 103 means 3 phase. |

Here is a screenshot with start address 70: Yesterday I created a small application to scan all addresses up to 65535, but I could only read address 0 to 123. For all the others I got an "Illegal data address" error back. So it seems like my inverter does not support the M160 data? |

Ok, at 70 you have value 101, which means you have a monophase inverter. There's a modpoll utility you can find, it's free, that does modbus queries via CLI. If you can't query past offset 123 it's strange. But could be that for smaller models like yours, they didn't enable M160 for some reason. Can you please show me what's available in qmodmaster starting at offset 100 for let's say 13-14 registers (the max available in your case)? What you could do is ask FIMER support for the register map of your specific model, so we can have an official document to analyze. |

Sure this is everything from register 100 to 123:
I'll try to contact FIMER support to see if I can get a register map. |

At 122 there's no M160 data. We need the official register map. |

I will release a beta with the following code for M160, that takes into account 3 different offsets: check those 3 offsets with qmodmaster, in first register you should find the value 160. try:
# Model 160 default address: 40122 (or base address + 122)
# For UNO-DM-PLUS/REACT2/TRIO inverters it has different offset
invmodel = self.data["comm_model"].upper()
if invmodel.startswith("UNO") or invmodel.startswith("REACT2"):
offset = 1104
elif invmodel.startswith("TRIO"):
offset = 208
else:
offset = 122
read_model_160_data = self.read_holding_registers(
slave=self._slave_id, address=(self._base_addr + offset), count=42
)
_LOGGER.debug("(read_rt_160) Model: %s", invmodel)
_LOGGER.debug("(read_rt_160) Slave ID: %s", self._slave_id)
_LOGGER.debug("(read_rt_160) Base Address: %s", self._base_addr)
_LOGGER.debug("(read_rt_160) Offset: %s", offset)
except ModbusException as modbus_error:
_LOGGER.debug(f"Read M160 modbus_error: {modbus_error}")
raise ModbusError() from modbus_error |

Hi, I'm trying to setup this integration with my ABB UNO-3.0-TL-OUTD inverter with the VSN300 WiFi logger card. I have installed HACS and the custom component, but when I try to add the device in HA I get an "Unknown error".
I see this in the logs:
As you can see it's reading some data from the inverter, but if fails in the read_sunspec_modbus_model_160 method. I had a look at the code and saw that it's trying to read data with an offset of 122 and a count of 42. I tried to do that myself but then I also get an read error in the Modbus Master tool.
After some experimenting I noticed that I can only read 2 register from offset 122, more than 2 registers will give a read error in the tool.
Do you have any clue why this happens? Should this component work with my inverter?
