He wants to make sure deCONZ starts connected to the second card, but there seems to be no parameter to specify the card or IP address to use? Or am I missing this (it is still hard to find a simple overview of possible startup parameters in documentation).
The user is using deCONZ on windows. It is native. But I do think this is even possible on Linux to have a dual network card? So it could be a common question as well. What if a machine is using two networks, with their own network mask, how to control deCONZ to use the right network?
