Thank you for answering . I wanted to ask you if beyond what is required you know a software that can replace the one that provides epever . Thank youModbus is more like the language spoken over the wires. You can have Modbus over RS485 or Modbus over IP (Ethernet)
Modbus would allow you to communicate/control any device that has a published modbus register map
Here's a Home Assistant post about connection an Epever 4210an to home assistant, might help.
EPEVER Modbus RS-485 Config
I just got done doing part of my code to get Home Assistant working my EPEVER solar charge controller. Here is the information and I hope it helps. I will ad Using the eBOX-TCP-02 RS-485 to an 80amp solar charge controller. Some command didn’t work on my controller, but they might work on...
Ok, thanks anyway for intervening and expressing your opinion.
Thank you very much for giving me this info. Above all, I own arduino!
Speaking of alternative software with other hardware, today with the software for windows monitor solar, an unusual fact happened. What happened is the zeroing of daily production. Usually the daily production is reset the next day, but this time in the hours near sunset I saw the reset. I checked epever 6314 an (10 days of life) and no alarm light on or anything else. I checked the time and it was in line with that of the system. The only doubt is that in the system parameters of the software there is a schedule to update the time and therefore I believe, that it coincides with my purchase made on June 16 and today's date June 27 (10 days, how many are expected for the update). Could it be this or do I have to consider it a sporadic case and that's it? Thank you .

Do not understand all the details + do not use the Windows app.
Thank you for your opinion.
I wanted to ask you which minina hardware version of raspberry can make the program work. PI 3 A can it be okay?Instructions for creating a dashboard to monitor your epsolar tracer setup

Runs on all Raspberry Pi's down to the $15 Zero 2W, therefore doesn't need Winblows. Using two cheap CH340 based USB to MODBUS converters from Amazon to get the data from the 4210's.
I prefer a scalpel to a Swiss Army Knife so I re-wrote this to lose the way-too-many "eye-candy" gauges shown on the link above and monitor two EPEVER 4210's. Stats are taken every ten minutes (graph X axis is not fully expanded in the screenshot) but interval can be adjusted by changing the cronjob. Every reading that has been taken since I took the first iteration online in late 2018 is still in the MariaDB database so I can go back in time and create charts, etc. in LibreOffice Calc. or use other analysis tools.
Can get real-time info by refreshing the page as often as needed. The data going to the db is completely separate.
Does just what I need and not too much. Fully extensible should I ever need to do so.
Not for the faint of heart and has a learning curve. Requires understanding of SQL, PHP, NGINX and Linux networking via the CLI. But going this route gets me exactly what I want. And it is FAST and light on system resources.
As a side benefit I learned a BUNCH of stuff that has proven to be very useful in lots of ways.
It actually port forwards for you via their website. Very hand. Nothing to do as they create the address for you and you just go to it from anywhere in the world to see your stuff. You can disable that feature or password protect it.
I try to put it working with node red, but was impossible for me. And with tutorial from yt..
Hi, considering you've done a great job, so I assume you can help me.Modbus is more like the language spoken over the wires. You can have Modbus over RS485 or Modbus over IP (Ethernet)
