Can moode use wifi to reach to internet?

[TheOldPresbyope]

I would say no myself, but I promised my sister I would ask:
She has no ethernet-bound internet access but she has a cell phone with a flatrate. Could moode access her phone in Wifi tethering mode in order to reach the internet, instead of going by cable to a router?

If you set-up an access point from your (well, her) phone, then you can tell moOde to connect to it, and voilà...
So, long story short: yes. (but... wasn't that easier to try, than to ask for...?)

Yeah, it should work, but don't forget there needs to be some device running the moOdeUI. If the player in question has a local touchscreen display, then no problem. If it has to be the phone, there's the problem of discovering the player, since there likely won't be any local domain name resolution.

Case in point, as a test I'm running a Google Pixel 6A phone as a WiFi hotspot which connects to my cellular phone service. 

I then configured a moOde 8.2.4 player to connect to this hotspot. The player's assigned IP address is 192.168.144.121, which certainly isn't obvious. I found it with the utilities I load on all my portable devices. Use this address in the Chrome browser on the Pixel and et voila there's the moOdeUI. Using the hostname or hostname.local convention doesn't work.

As an aside, I also had no problem connecting an iPad to the same Hotspot and running the moOdeUI on it.

Internet radio stations seem to be playing ok, mostly, I experienced some breaking up on one but I think that was an Internet problem.

YMMV
