Why local HTTPS
Over HTTP, all control works. Over HTTPS, browsers also let you keep the screen on during the show and install the app properly. The account password is only accepted over HTTPS (or over HTTP from the engine machine).
Install the certificate

http://<engine address>:7810/installer. - Follow the steps for your system: profile on iPad and iPhone, certificate on Android, Windows or Mac.
- Then open
https://<engine address>:7811.
