Serial number 27********* #574

Open sandridgepark opened 2 months ago

sandridgepark commented 2 months ago

Hello I have a serial number starting Serial number 27***** firmware LSW3_32U_5406_1.06

I cannot for the life of me get this to connect

Anyone know what file I should be using

THANK YOU !

gavrik commented 2 months ago

The same for me. Can't connect.

Seems that pysolarmanv5 library is not support 27*** serial number for the solarman logger.

modbus = PySolarmanV5("192.168.88.206", 2796911391)
print(modbus.read_holding_registers(1476, 1))

And error was

What version of pysolarmanv5 are you using? Please enable debug logging (example below) and attach the output.

modbus = PySolarmanV5("192.168.88.206", 2796911391, verbose=True)

Are you using a Sofar inverter by any chance? Another user reported a similar issue earlier today but it was found that the wrong Modbus function code was being used.

gavrik commented 1 month ago

I am using Deye 3 phase 12kwat inverter.

tragram commented 1 month ago

Interestingly, the deye-controller library which is also based on pysolarmanv5 can read all the data correctly from my Deye SUN-10K-SG04LP3-EU even with a 27xxx logger, so the issue appears to be in this library/configuration...

gavrik commented 1 month ago

Confirm. deye-controller can read inverter with 27xxxx serial number.

>>> from deye_controller import HoldingRegisters, WritableRegisters
>>> from pysolarmanv5 import PySolarmanV5
>>> inv = PySolarmanV5('192.168.88.206', 2796911391)
>>> register = HoldingRegisters.BMSBatteryCapacity
>>> res = inv.read_holding_registers(register.address, register.len)
>>> register.value = res[0] if register.len == 1 else res
>>> print(register.description, register.format(), register.suffix)
bms_battery_SOC 100 %
>>> inv.disconnect()
githubDante commented 1 month ago

@gavrik print(modbus.read_holding_registers(1476, 1)) - 1476 is not a valid address for Deye. What you receive in the response is an exception code 0x05 which indeed is not a valid Modbus frame.

See here how to enable the debug logging if you still have connectivity issues.

gavrik commented 1 month ago

@githubDante Thanks for you support. I recheck the integration, remove and add integration with deye_sg04lp3.yaml config and I happy can say that it is working! I can see all parameters what I need and it is changing. I have 3Phase 12kwatt inverter Thanks.

Glad to hear. It sounds like pysolarman v3.0.2 has fixed the issue for you. Hopefully @StephanJoubert can get around to releasing a new version of the Solarman integration soon with a versioned depends on pysolarmanv5.
