It's as easy as:
- Buy the suggested modules
- Connect the 8 wires
- Flash the firmware following the instructions
- Configure it to your wifi, let it reboot and show it is connected
I know that is simplification, but really, that's more or less the instructions.
Special thanks to Mark for making this such a nice integration. Code that "just works"- remote acts like it's on the original TIU- it's magic for the WTIU that didn't natively support the remote. This is fundamentally game changing.
