VAHEAT USB Serial Controller Wrapper

A Python wrapper class of serial controller and interactive CLI for VAHEAT controller

Download

• Download a script 'pyvaheat.py'. (Not uploaded to pypi yet.)
• Install pyserial module by pip install pyserial if not installed yet.

Usage of CLI

Run pyvaheat.py. Prompt ask commands for API like 'connect', 'start_heating' and 'get_info'. First of all, connect to device. If serial port is not specified, program will detect connected VAHEAT automatically. See also an wiki page for an example.

>connect

After establishing connection, prompt should show a serial number of your device. When a command needs parameters, prompt will ask parameters formatted as JSON. Try inputting API commands in user manual of VAHEAT.

>get_info
>get_status
>start_heating
>  {"mode":"auto","temperature":45}
>stop_heating
>exit

Usage of class

Your python script can use VAHEAT device by importing Vaheat class. See also an wiki page.

1. Import the Vaheat class

from pyvaheat import Vaheat

2. Initialize and connect

If no serial port is specified, this class will use the port of the first device found.

# Instantiate
vh = Vaheat()
vh.connect()

3. Send commands by method of the class

# get_info
print(vh.get_info())

# start_heating
vh.start_heating(mode='AUTO', temperature=40)

4. Disconnet from the USB device when done:

vh.disconnect()
