Two Epever on one RS485?

[Emmpunkt]

Hi,
is it possible to use one USB RS485 Adapter with two Epever in parallel?
I trying it for several hours now, but i´m failing ;)
My Raspi is not even starting if i don´t unplug the USB..

The Error Message i get is: Error: Client Not Ready To Read At State reconnecting
Sometimes one of the Units is working, but never both at the same time. Sometimes Unit-ID 1, sometimes ID 2

You might be able to change the device address of the 2 Epever. By default they might have the same address. With the LCD remote display in the settings, you can do that. I'm not saying this will work, just that this might be a prerequisite.

They both have different addresses. 1&2. I made this with the Epever Software. TerryFrench ***@***.***> schrieb am Fr., 22. Juli 2022, 07:14:

turn on logging / trace on the node getting the data. Also depending on your hardware and how you transfer the bits, you might be able to get some logging there too (if you have a serial/485 to IP conversion for instance). If you see packets from both devices, it might be possible to change the NodeRed code to split the replies from each device. That would be my *guess* here.
