how can Control/write Temperature value with RS485port, from Django web?

Question

''''Hello, I have PID temperature controller with RS485 communication port. I can read & write the resister values by connecting my 'controller' to serial PORT(com3).

I want to Monitor and control the room temperature from Django-Web. please help me with this. I am completely new to Django & python however somehow I managed this much with the help internet.

here is my code from where I can read and write the resister values. ''''
