Were you able to make any progress on this? I am looking to do the same and am unsure on how to actually configure the secondary Ethernet port on the revpi connect.

I was able to restore pictory to a working state by running

sudo apt-get install --reinstall revpi-webstatus pictory

However, I am still experiencing the error:

Hi Amar,

I just realized that this revpi still has the old modbus library "libmodbus5/oldstable,now 3.0.6-2 armhf"
I'm assuming this could be the root cause of my issue. Is there any way to update this library remotely without re-imaging the controller?
