Pioneer receivers work with Onkyo app but only one at a time

It is indeed possible to control Pioneer NC-50DAB or Pioneer SX-S30DAB with the Homey Onkyo app on port 60128 (Homey Pioneer app does not work).

Question is how to control both individually since the IP and port config in the Onkyo app is related to the app and not to the individual device instances (unlike the general Homey principle). This means you can only have one receiver in your setup.

Any ideas?
