Creation Script For My Avanza Stock Trackers

A new utility script to automate the entity creation for my avanza stock trackers.

The Problem

In my article Using-Homeassistant-As-My-Self-Hosted-Stock-Alert I described how I used Homeassistant to keep track of stocks and send me automated alert when lower or upper tresholds are met. After adding a few of them I got annoyed with the time consuming process of copy&pasting that was needed to add the new sensors to my configuration.yaml.

The Script

I chose Python instead of bash or powershell because I wanted the script to run on my Windows 10 laptop as well as on my Ubuntu server directly.

click is a really great Pthon lib that enables you to write a beatiful command line interface in a few minutes. I used it together with Template which is part of the Python standard library to create this script:

"""Create new Avanza Stock Sensors."""

import click
from string import Template

TEMPLATE_FILE = "avanza_stock.yaml.template"

@click.argument('name', type=click.STRING)
@click.argument('id', type=click.INT)
def cli(name, id):
    """Create new Avanza Stock Sensors.

    NAME: The name of the stock.\n
    ID: The Avanza id of the stock. Obtainable via the URL.
    filein = open( TEMPLATE_FILE )
    template = Template( )
    result = template.safe_substitute(name=name,id=id)
    filename = f"avanza_stock_{name}.yaml"
    with open(filename, "w") as f:

if __name__ == '__main__':

This script is located under <config>/packages/avanza_stock and uses the following template to create new yaml files under the same directory. These will get picked up by Homeassistant via the packages mechanism.

          and states('input_text.avanza_${name}_max') not in ['unknown', ''] }}
      - platform: template
        value_template: >
          {{ states('sensor.avanza_${name}') | float < states('input_text.avanza_${name}_min') | float
          and states('input_text.avanza_${name}_min') not in ['unknown', ''] }}
      - service: notify.kevin
          message: >
            {% if states('sensor.avanza_${name}') | float >states('input_text.avanza_${name}_max') | float %}
            "Stock alert: {{ state_attr('sensor.avanza_${name}','name') }}:
            {{ states('sensor.avanza_${name}') }} {{ state_attr('sensor.avanza_${name}','currency') }}.
            Over threshold of {{ states('input_text.avanza_${name}_max') }}"
            {% else %}
            "Stock alert: {{ state_attr('sensor.avanza_${name}','name') }}:
            {{ states('sensor.avanza_${name}') }} {{ state_attr('sensor.avanza_${name}','currency') }}.
            Under threshold of {{ states('input_text.avanza_${name}_min') }}"
            {% endif %}

I can now use the following command to create a new sensor without the need for copy pasting:

python pfizer 4145

You can find the Python script and the template file here and as always you can find the whole configuration in my repo under
