WiFi vs Ethernet #53

Closed rark-ha closed 2 years ago

rark-ha commented 3 years ago

I had my inverter connected via Wi-Fi until I had time to run an ethernet cable to it. Switched it over to an ethernet connection and iCloudsolar etc continued to work without issue.

But solaroit.py kept reporting 'Modbus connection failed' and 'Failed to scrape inverter, sleeping until next scan' in the log file.

I'd updated the config.py to the ethernet ip address but it didn't work still. I could run a Modbus poll from another machine without any issue.

Also tried;

I turned wifi back on (and ethernet still on), pointed config.py to the wifi ip, and it started working again.

Why the issue with ethernet?

rark-ha commented 3 years ago

I've discovered that I now cannot connect to the modbus. I've tried it from a few different systems but it won't read the input registers (e.g. 5000 + 1000) as it returns illegal address details. The only thing I can pull is the holding registers 4999 + 10 (so I know it's connecting).

From the inverter web interface I can read these input registers from the testing page so I know the address is correct.

Any ideas?

This is the error I'm now getting trying to read the input registers.

The full debug log. I'm at a loss as to why it's stopped working.

Try the latest code which addresses the pymodbus version issue.

rark-ha commented 3 years ago

Still get the same error.

bohdan-s commented 3 years ago

Hi, I am getting the same issues. New install of a Sungrow SG7.0RT. I have the modbus map from Sungrow so know I am hitting the right registers. I can read the holding registers OK and run it from the web interface. I have moved from WiFi to LAN and still same issue.

This is my exact issue. Perhaps coincidental that it was working and stopped when I went to LAN, but it doesn't matter if I remove LAN now or not. I have the same error log file as you.

Hi, please see #66, I have created a new library SungrowModbusWebClient to pull the modbus via HTTP requests. It's dirty but I have been running it now for a week.
