I think this is exactly what Pangolin was designed for and does.

Not knowing what your goal is, I’ll start with this: I had very similar hardware to you, and while I was fine with the Omaha Ui, I just never could get it setup how I needed or wanted. I had the er605v2, 3 eap615 wall WiFi 6 apps, and a switch for PoE from the Omaha line but don’t recall the model. I just finally gave up on it, and moved the er605 and wall WiFi APs to OpenWRT. Setup my network with a dumb PoE switch and 4 VLANs and haven’t looked back. It all just works and I almost never mess with it. I’m not saying it wasn’t a little work initially, but it’s been worth it. I’ve now added a 4th wall WIFI (just download a backup of an existing one, install openWRT and restore to the new one. Change the IP and done.) I added two managed PoE Switches with OpenWRT as well. So it’s allowing me to grow as I need to.
