Pioneers AV receivers support network control over a proprietary protocol (SC-55 IP) that used a raw IP connection to the AV receivers port 8102.

This provides the possibility to easily control the AV receiver from the smartphone with tools like Tasker to automatically turn on the AV receiver, switch to the Bluetooth adapter, connect to the receiver and play music just by pressing one button instead of fiddling around for a minute will everything is working.
However, Tasker itself does not support RAW IP connections and in my experience the Send/Except-Plugin which could be used for sending the commands to the receiver, isn’t as stable as I’d wish that it was.

So I wrote a little flask restful application that works as a HTTP to RAW Pioneer gateway.
The script is hosted on a little Raspberry Pi that runs 24/7 and forwards the commands to the AV receiver.

The Script itself is hosted in the following repository:

To allow the receiver to be woken up when powered of it is necessary to enable the “Network Standy Mode”
