When logged into brandmeister.network, go to
Services -> SelfCare
.
To get your hotspot listed (there comes a new menu item below Services) set a hotspot selfcare password. Then use this password on your Openspot to connect (connector menu) to the BM Master server.
This should make your hotspot gets listed in your BM Account. Click on your DMRID under the new menu item "Hotspots" and you can finally manage your static TGs. Or dynamic. etc..
