Do you think it matters that i could only install pyserial with the command
‘sudo pip3 install pyserial’ not ‘sudo python -m pip install pyserial’ as you have it?
I have back RS-232 on; I had it hooked up to a HTPC w/ USB to serial cable, so know it accepts that.
Does it matter if when i run this line alone in Putty:
‘python /usr/local/bin/tcp_serial_redirect.py --rts 1 --dtr 1 -P 1337 /dev/ttyUSB0 19200’
it return SyntaxError
How is the 1337 port determined? does it need a port, is this random?
The log shows
17-04-25 09:31:33 ERROR (Thread-4) [russound.russound] Error trying to connect to Russound controller.
17-04-25 09:31:33 ERROR (Thread-4) [russound.russound] [Errno 111] Connection refused
17-04-25 09:31:33 ERROR (Thread-4) [homeassistant.components.media_player.russound_rnet] Not connected to 127.0.0.1:1337
But, i can see serial device is detected
