The way I got it to work is:
Plug in HDMI
Auto detection appears
Select “My provider isn’t listed”
Searched for “zgemma”
Selected “Zgemma”
Channel up/down does not work
Select No (it did not change the channel)
Searched “star”
Now I have a zgemma H2S, it wasn’t there but the closest match that worked is “H2H”
It now changes channel, guide is EPG, etc. But it is very slow for me, maybe it’s my hardware?
