Solis- No devices or entities- Newbie

[Richard7619]

Hi I'm a Newbie to HA but with help on here I’m making progress.

I have installed the hardware and worked through this project
https://github.com/Jumpy07/Solis---SolisCloud-and-Home-Assistant

When I get to the Solax modbus integration I can not get devices or entities to load.

My Inverter is a Solis RHI-48ES-5G-DC, serial number starts 6031.
I checked the solis plugin in file editor and that serial number is listed.

I switched on the debug log and get the following:

File "/usr/local/lib/python3.11/site-packages/pymodbus/client/base.py", line 191, in execute
raise ConnectionException(f"Failed to connect[{str(self)}]")
pymodbus.exceptions.ConnectionException: Modbus Error: [Connection] Failed to connect[ModbusTcpClient(192.168.1.218:502)]

File "/config/custom_components/solax_modbus/plugin_solis.py", line 53, in _read_serialnr
inverter_data = hub.read_input_registers(unit=hub._modbus_addr, address=address, count=8)

any help would be appreciated.

@Richard7619 there is no connection between HA and your Modbus interface. It's either port, protocol or IP wrongly configured.

This is the status of the Elfin EW11. Should sent and received frames be on different?

@Richard7619 It's hard to advise as I don't use that solution. It would be best if you asked for connectivity and configuration help at the project's source that you have followed.

[Richard7619]

It turned out to be a wiring issue. I now see 1 device and 143 sensors.

@alienatedsec The Solax integration now shows list of controls, sensors, configuration and diagnostic but the status of all sensors is "unknown". The solis cloud is pulling all the data into the solis app so any ideas on how I get the data in Solax?

Thanks,

@Richard7619 post a picture of your "2 Masters, 1 Slave hub", please. It could be that they sent you the wrong unit and it will not work as intended. Also, you can check this theory by unplugging the Datalogger and see if SolaX will work after reloading.

@alienatedsec I removed the datalogger and now I have data in Solax. I'll post photos
