Install
Lucerra is sideloaded over adb. You need a computer on the same network as the TV and Android platform-tools.
1. Enable network debugging
On the TV: Settings, Device Preferences, About, press Build several times to unlock developer options. Then turn on USB debugging (network debugging on some boxes).
2. Connect and install
Download Lucerra-Launcher-v0.1.0.apk from the GitHub release, then run:
adb connect <tv-ip>:5555
adb install -r Lucerra-Launcher-v0.1.0.apk
Accept the debugging prompt on the TV the first time you connect.
Next: make it your default Home.
