with later versions you have the problem of false standby and the useless consumption of current, with H8 old version I don't have it.
The version I use is the: 2020 12 07 all subsequent ones do not bring any advantage for me, moreover I have H8 old version and I don't know if these new firmware have also been tested on this one.
Hellobox 8 flaws we have reported have never been fixed to date.
