how to connect to OBD-sensor with python?

Question

I can't reach connect to the remote obd-sensor. Tried it out with the python-obd but there is no explanation about remote connection (Connection through the phone text messages is good). In the python-obd doc I see only "connection string" without any explanations what is that string and how to create it. So this code:

import obd
from obd import OBDStatus
connection = obd.OBD("61.144.222.116:2332")
print(OBDStatus.NOT_CONNECTED)

returns just

[obd.elm327] [Errno 2] could not open port 61.144.222.116:2332: [Errno 2] No such file or directory: '61.144.222.116:2332'

So I can't do anything with it. Model of sensors is SC20.

The "connection string" is the name of the RS-232 serial port where your OBD is connected. OBDs have to be plugged in to your computer directly. You can't connect over a phone or over the internet.

It's possible to get OBD Bluetooth dongles that can be read remotely.
