It is my only project where i had to do real hacking. Roku does not provide documentation on messaging protocol between Voice Remota and the TV Set. So i had to do some sniffing.
This project will turn your ESP32 microcontroller to a proxy device for Private Listening to a Roku TV in a Chrome browser tab on your PC (or MAC).
Private listening on the Roku app (native IOS , Android) is a great feature for those looking to watch some late-night movies without disturbing family around them. This feature allows you to watch Roku TV and listen to it privately on your headphones that are connected to your phone or tablet.
Until now you needed to install Roku app on your Android or iOS device.
Using this proxy will remove that limitation and allow you to do the same on any device with Chrome browser on it.
