The Bravia Quads, for as good as they sound, were severely lacking in the automation department. The only hint that they CAN be automated is a switch in network settings called “External Control”. But there’s zero documentation on it.
After enabling and doing a quick scan with nmap, I found that port 33336 opened up. And after a bit (a lot) of internet sleuthing I happened upon this gent’s post that mentions the same port, but in use for the sony DN-1070 receiver.
After some testing with the roomie remote app. I found that using the DN-1070 Zone 1 profile worked! So I started running pcaps while sending volume commands from the app to get some idea as to the schema.
While ugly, even this tiny bit of data was enough to get the ball rolling. So after probing hard using netcat using the schema found here… I was able to get volume, power, and source working using netcat!
The only command I could get to work using the roomie app was the volume. I just guessed likely commands based on the other API docs from Sony.
The custom integration is linked below. Please note that I am not a coder. I sat down to take a stab at automating my quads last night. And I vibe-coded the ha integration in a few hours this afternoon using cursor
