DIYP definitely look interesting but i will have to wait till i get an mi box first.For Hisense you can try ott player. It is a decent iptv app, it does have a server end for you to load your iptv playlist.
I have been playing with OTT player for sometime, until i found DIYP chinese app which is much more superior as it support many codec and protocol as well as it is formatted in txt code.
Vidaa Store only have a good free one SS IPTV which i am using it atm
