Are you wanting to use TVH for IPTV or OTA?
If you want to use OTA, you'll need a tuner of some sort.
If you want IPTV, you'll need at minimum a URL that will get to access to the video stream(s).
If you want to use TVH as a PVR, you'll also need access to EPG data in XMLTV format.
If you have a URL to an mpegts stream, you can construct a .m3u file like this:
#EXTINF:-1,Name of channel
https://address.of.provider/path/to/channel
If you just have an IP address and you need to log in, it
might be possible to construct a URL containing the login
credentials, but how this is done really depends on the provider.
Your options are: 1) Find someone else who has done the same thing & can help, or 2) Log into your App while sniffing the network with something like wireshark, which will reveal the URL the App is accessing after you've logged in - this may or may not give you something you can use with TVH.
If you want to get TVH working, I suggest you look for a free IPTV URL or .m3u that you can use to test. There are quite a few that are free to access [e.g. PlutoTV, Deutsche Welle, Bloomberg, Euronews].
