An ESP32 IR receiver to control the volume of Devialet speakers.
This project uses a IR Sensor to convert the IR signals of a remote to the following http post request:

{"volume":47}

{"volume":50}
Allowing to control the volume of a Phantom Speaker from an Apple TV Remote.
Finding the correct setup took some research as the ESP32-C6 is pretty recent and not completely supported by the tools I was using.
Here is what devices were used for the project:
- An Apple TV 4K (model=AppleTV11,1;iOS=17.6)
- An Apple Siri Remote (Charging via lightning)
- A LG TV (Model 42LD420)
- A Devialet Phantom II 98dB Speaker (Link to the website)
- A Seeed Studio XIAO ESP32C6 Board (Link to the official product, The website on which I bought it)
- IR Receiver used for the build.
- Clone the repo
- Open the
devialet-ir.code-workspacewith VSCode - It will suggest you to install platformIO, do so
- While it installs, Connect the IR receiver to the board. The S (Signal) pin should go to D10 on the board, the middle pin to the 3v3, and the I pin to the GND (Ground)
- Connect the ESP32C6 Board to your computer with a USB-C cable
- The PlatformIO should now be installed
- A new tab will appear on the left bar with an alien face
- From that menu you will be able to
Upload and Monitorthe firmware - edit the
src/secrets.hppfile to enter your wifi credentials
Sometimes the board refused to be flashed. To fix it I had to:
- disconnect from power/computer
- stay pressed on the tiny B button next to the USB-C connector
- while still pressed reconnect to the computer
- The yellow light stays ON until it is connected
- The device tries to connect to the wifi for 15s
- Once connected to the wifi, the yellow light turns off
- It then looks for the IP address of the Phantom Speaker
- The yellow light will turn on on each try
- After 10 tries, it will stop looking and blink with an error pattern if there is one
- If everything went well, the yellow light will turn off
# Short flashes every 0.1s (0.1s OFF - 0.1s ON)
The device was unable to connect to the wifi
=============
# Short flashes every 0.4s (0.4s OFF - 0.1s ON)
There was an error starting the network discovery to get the IP address of the Phantom Speaker
