Hi Adrian, did you see the last log files ?
Andre
Looking at the log, it seems you have two loggers:
Endpoint 1
10.10.0.253 : 8899
Solarman V5
Endpoint 2
10.10.0.30 : 502
Modbus TCP
I am going to add new app settings so you can switch off automatic probing and define everything manually as it seems the probe might be upsetting the logger so it fails to connect after the first attempt. Hopefully I will get this done this evening.
Hello Adrian,
That is correct. The installer connected the Wi-Fi dongle, which communicates with the SOFAR server and allows the SOFAR app on my phone to retrieve the inverter information.
However, the inverter also has an Ethernet connection, which I am currently using for testing.
It seems that both connections behave differently.
Ideally, I would like to retrieve the inverter data locally through the Ethernet connection, while leaving the Wi-Fi dongle connected solely for communication with the SOFAR server and the app on my phone.
If this is possible, that would be the preferred setup.
The reason I cannot simply disable or disconnect the Wi-Fi dongle is that I would then lose access to the inverter information in the SOFAR app on my phone.
However, I can disconnect the Ethernet connection if you would like me to test whether this has any effect.
kind regards, Andre
I have published a new test version. You can now switch from automatic detection to manual setup. In manual mode it relies on the Manually added device.
Hello Adrian,
I have now installed version 1.1.59 as a test. As you mentioned, I can see that it is a newer version, but unfortunately I do not see any improvement so far.
Just for your information: the Ethernet port has IP address 10.10.0.30, and the Wi-Fi dongle has IP address 10.10.0.253.
As you can see in the screenshot, I manually entered IP address 10.10.0.30 together with a serial number. I have to be honest, I took the serial number from the log, as this is the only serial number I know or can see.
Furthermore, I can still see in the log that it is trying to connect to 10.10.0.253, which is the Wi-Fi dongle.
I am also now getting several error messages when I open the configuration section of the SOFAR application. Please see the attached screenshots.

The new test version is 1.1.60.
The new settings screens look like this:
Make sure you hit save after changing the Automatic to Manual.
Just add the 10.10.0.30 IP address and set it up as a Plain MODBUS TCP protocol, Keep the connection open, then try various Register Maps. You can use the Test button to see if it returns anything useful.
Hello Adrian,
Yes, sorry. I now have the correct version and have configured it as you suggested.
I correctly received the following message:
Testing 10.10.0.30:502 (Plain MODBUS TCP, slave ID 1)
TCP connection established
Using register map: sofar_g3hyd
Read 39 values (grid frequency 50.01 Hz)
The connection is working
settings i set:
i can add my solar now:
There is just one thing I noticed: my batteries are 2 × 5 kWh, but I can only see one of them, and I cannot add another one. Both batteries are connected to the same inverter (same make and model as everything).

I have the same, 2 x 5 kWh batteries, but the inverter only reports the combined information and has no way to report individual information.
I’m not sure if other inverters can report individual data, but if you can find the appropriate registers I can add support for it.
Hi Adrian, thanks for the app. In manual mode it runs nicely on my Sofar HYD 15KTL-3PH (LSW-3 logger, app 1.1.60, Modbus TCP on port 8899, register map sofar_g3hyd).
One bug: the Grid device always shows the negative of the house consumption. In lib/sofar_g3hyd.json both Grid_Power and Consumption read register 1199 (0x04AF, load power). The same is visible in the log in post 228 above (Grid_Power 590 / Consumption 590).
The grid (PCC) power is in register 1160 (0x0488, ActivePower_PCC_Total). It is a signed value in 0.01 kW, which is why it looked like 65535 kW in post 11: 0xFFFF there is simply -1 = -0.01 kW (grid almost zero).
Register dump from my inverter, registers 1152 to 1207:
- 0x0488 = 1 (0.01 kW); per phase 0x0493 = 26, 0x049E = -67, 0x04A9 = 43, sum 0.02 kW
- 0x0485 = 160 (inverter output 1.60 kW), 0x04AF = 155 (load 1.55 kW)
- At the same moment: PV 4000 W, battery charging 2220 W, load 1760 W, so grid is about 20 W export, which matches 0x0488.
Suggested fix: Grid_Power → registers [1160], rule 2 (signed), scale 10. Positive = export, so the sign handling of the Grid device can stay as it is.
FYI: with Solarman V5 my logger returned “Invalid V5 packet start” because Home Assistant was polling the same logger over Modbus TCP (the logger sends the responses to all connected clients). With HA stopped, Modbus TCP on 8899 works fine.
I have published a new test version. Can you try that to see if it fixes the issue?
Thanks a lot Adrian, 1.1.61 fixes it. The Grid device now reads its own value. At night it showed 2.63 kW import while the house load was 2.50 kW. This morning it hovers around zero (between -100 and +70 W) while PV gives 8.2 kW, the battery charges 2.9 kW and the house uses 5.1 kW, which matches the inverter keeping the grid at zero. Import is positive and export negative, as expected.
Thank you for the quick fix and for the great app!
