newbie tips

Hello,

Can I use py-brickshema to make a Brick model or would I only be using py-brickshema in validating an existing Brick model? Apologize for my ignorance I have a lot to learn...

I am working with configuration files like this below in YAML format that represent a BACnet devices inside a building:

devices:
- address: '12:40'
  device_identifier: '601040'
  device_name: MTR-01 BACnet
  points:
  - object_identifier: analog-input,8
    object_name: Outlet Setp. 1
  - object_identifier: analog-input,9
    object_name: Outlet Temp. 1
  - object_identifier: analog-input,10
    object_name: Inlet Temp. 1
  - object_identifier: analog-input,11
    object_name: Flue1/Pool Temp.
  - object_identifier: analog-input,11
    object_name: Firing Rate 1
  read_multiple: true
  scrape_interval: 600

Which I can modify at will. I am taking a stab in the dark at what it would look like in Brick...? Assuming people starting out are just manually adding the meta data into there processes?..

devices:
  - address: '12:40'
    device_identifier: '601040'
    device_name: MTR-01 BACnet
    type: Boiler_Controller
    points:
      - object_identifier: analog-input,8
        object_name: Outlet Setpoint 1
        brick_class: Setpoint
        brick_function: Temperature
        brick_location: Boiler_Outlet
      - object_identifier: analog-input,9
        object_name: Outlet Temp 1
        brick_class: Sensor
        brick_function: Temperature
        brick_location: Boiler_Outlet
      - object_identifier: analog-input,10
        object_name: Inlet Temp 1
        brick_class: Sensor
        brick_function: Temperature
        brick_location: Boiler_Inlet
      - object_identifier: analog-input,11
        object_name: Flue1/Pool Temp
        brick_class: Sensor
        brick_function: Temperature
        brick_location: Flue
      - object_identifier: analog-input,11
        object_name: Firing Rate 1
        brick_class: Sensor
        brick_function: Firing_Rate
        brick_location: Boiler
    read_multiple: true
    scrape_interval: 600

Where I then I can read it into Python with a script something like this:

import yaml

def read_bacnet_config(file_path):
    with open(file_path, 'r') as file:
        config = yaml.safe_load(file)
        return config

def print_device_attributes(device_config):
    for device in device_config['devices']:
        print(f"Device Name: {device['device_name']}")
        print(f"Device Identifier: {device['device_identifier']}")
        print(f"Device Address: {device['address']}")
        print("Points:")
        for point in device['points']:
            print(f"  - Object Name: {point['object_name']}")
            print(f"    Object Identifier: {point['object_identifier']}")
            if 'brick_class' in point:
                print(f"    Brick Class: {point['brick_class']}")
            if 'brick_function' in point:
                print(f"    Brick Function: {point['brick_function']}")
            if 'brick_location' in point:
                print(f"    Brick Location: {point['brick_location']}")

# Example usage
config_file_path = '201201_brick.yml'
config = read_bacnet_config(config_file_path)
print_device_attributes(config)

I am still trying to figure out how to properly implement a Brick model manually on some BAS devices inside a building through config files like this and where py-brickschema would fit into the process. Any tips greatly appreciated.

For this building there would also be similar config files for VAV boxes, AHU, and a chiller.
