This repository contains a custom watchdog for the Czech real estate marketplace Bezrealitky.cz.
The watchdog is a simple Python script that tracks relevant offers based on a customizable filter and sends an email notification whenever it encounters any previously unseen offer. The script can be run locally or deployed to Heroku or a similar service. S3 is used for state management (tracking of already seen offers) and SendGrid is used for sending e-mails.
To configure, set up the .env file according to .env_template. You might also want to adjust the queries and parameters in graphql_queries.py and the polygonal location filter in watchdog.py.
