App to allow access to enigma2 box using android box or android phone

You can use EnigmaTV software/plugin/Apps, it also transcodes allowing you to have smaller streams (as internet home connection often are limited in bandwith).

What is wrong with the original dream player on google play store. (not the android tv version)

just don't selected https or transcoding on first setup and it should all work fine.
You will need to set a password on your box first though. most people just have user:root pass:root for simplicity.
And i have to click zap first as I only got one tuner.

but if you type enigma2 into google playstore, there are loads of similar apps.
