Install second Xiaomi Gateway on slave

[Franzie]

Hello

I have a Domoticz system consisting of 1 master (raspberry) and two slaves. On the master is a Xiaomi Gateway V2 working. All working well without any problems. Bacause I cannot reach my carport with the gatway I want to install a second Xiaomi Gateway V2 on the second slave.
I now the instruction about installing a Xiaomi Gateway. Do I have to follow the same instructions mentionned in this instruction for my second GW to keep in mind that it has to be installed on a slave and not 2 gateways on one RPi!

Or is there another way to install a second Gateway on a slave?
