Hi,

I can't test this with the phone app, because my Powerline adapters don't have Wi-Fi, but my experience with the tpPLC Utility for Windows is that custom device names are saved with the tpPLC Utility and not inside the actual Powerline adapters.

If I custom-name my Powerline adapters on one computer and later start the tpPLC Utility on a second computer it shows the default names again. I can then also enter and save different custom names on that second computer, but when I open the tpPLC Utility of the first computer again, then I am shown the device names entered previously in the tpPLC Utility of the first computer.

So, I would say either the tpPLC app you are using doesn't save the names you've entered (bug?, have you given the app the required permissions?) or the saved data of the tpPLC app somehow gets deleted.
