Problems with Multiplus network priorities

Hi all,

I just installed my new multiplus II GX and connected it to my wifi network. Works fine. Via wifi it is also connected to an openDTU and collects data from the DTU.

For the ESS setup I bought an EM24 ethernet (needed about 7-8m cable so i didn't get the rs485 version). I wanted to connect the EM24 ethernet to the ethernetport of the multiplus with a static and direct point to point connection. No routers, no inthernet and no other devices inside this network.

This also worked fine.

My Problem is now, when I start the Victron apperently it prioritieses the LAN conneciton over the WIFI (I found this also in the manual). Now I can't ping the multiplus anymore, can't get a ssh connection and the DTU data are not displayed anymore. As soon as i diconnect the LAN cable to the EM24 everything comes back.


Any Ideas how to solve that issue?

Suggestion (assuming WiFi router has an ethernet port, most do)

Disconnect the multiplus from WiFi.

Put in an ethernet hub

Put a cable connection from the WiFi router to the ethernet hub

Connect multiplus to ethernet hub

Connect EM24 to ethernet hub.

I don't see the point of using the EM24 ethernet if you still have a direct P2P connection to the GX device.

You could have also just extend the RS485 cable.

The RS485 connection is way more stable and you could have used the new EM540 instead.
