pySerial VS busylight

Code your REST endpoint to use something like pySerial to send the message to your device

If the Tach is the older style I think this would be a great first project. If you need to emulate CAN it’s going to be a rather more complex project. python CPU/RAM utilizationpython Serial communication library

I haven't, but I would try a Linux box with two serial ports, connect both things to it so it's literally man in the middle. The PySerial module for Python, and it has an example bi-directional Serial to TCP/IP relay including a threaded serial listener, you might be able to hack that into a Serial <--> Serial relay with custom logging/interception fairly quickly.

Connecting to the Russound device is only possible by TCP, you can make use of a TCP to Serial gateway such as tcp_serial_redirect

Look in source https://github.com/pyserial/pyserial/blob/master/serial/serialcli.py

The code that runs on the Raspberry Pi needs to listen for incoming data over the serial connection. Several libraries exist, we will choose the Python library pyserial.

Try pyserial

I'm trying to compile a slight change in the code for https://github.com/buildcomics/busylight
