How to integrate a Yamaha YAS-209 Soundbar?

Hardware

I have a WiFi enabled Yamaha YAS-209 Soundbar, which doesn’t support the MusicCast integration.
Does anyone have a way who I can integrate it in Homeassistant?

Best Regards

I’ve got a YAS-203, that doesn’t even have WiFi. I integrated it using an ESP32 similar to this. I have the “Lyrion Music server” addon for HA, and the “squeezelite-esp32” software on the ESP.

You can connect them either by LINE or Bluetooth (the latter is less reliable but I have it connected this way and it works 90% of the time). Another way would be to use ESPHome software but I haven’t tried that.
