TGTG Scanner

TGTG Scanner observes your favorite TGTG Magic Bags for newly available items and notifies you via mail, IFTTT, Ntfy, Telegram, PushSafer, Apprise or any other WebHook. Notifications will be sent when the available amount of Magic Bags rises from zero to something.

Additionally, the currently available amounts can be provided via an HTTP server.

Running in a docker container the scanner can be seamlessly integrated with OpenHab, Prometheus, and other automation, notification, and visualization services.

Installation

You can install this tool on any computer. For 24/7 notifications I recommended an installation on a NAS like Synology or a Raspberry Pi. You can also try to use a virtual cloud server.

If you have any problems or questions feel free to create an issue.

For configuration options please refer to the projects wiki: Configuration

You have the following three options to install the scanner, ascending in complexity:

Use a prebuilt binary

This is the simplest but least flexible solution suitable for most operating systems.

The binaries are built for latest Ubuntu, MacOS, and Windows running on an x64 architecture. If you are using another architecture like arm (e.g. RaspberryPi, Synology, etc.) you have to run from source, compile the binary yourself or use the docker images.

1. Download latest Releases for your OS
2. Unzip the archive
3. Edit config.ini as described in the Wiki
4. Run the scanner

You can run the scanner manually if you need it, add it to your startup or create a system service.

The executables for Windows and MacOS are not signed by Microsoft and Apple, which would be very expensive. On MacOS, you have to hold the control key while opening the file and on Windows, you have to confirm the displayed dialog.

Run with Docker

My preferred method for servers, NAS, and RapsberryPis is using the pre-build multi-arch Linux images available via Docker Hub. The images are built for Linux on amd64, arm64, armv7, armv6, and i386.

1. Install Docker
2. Copy and edit docker-compose.yml as described in the Wiki
3. Run docker compose up -d

The container automatically creates a volume mounting \tokens where the app saves the TGTG credentials after login. These credentials will be reused at every start of the container to avoid the mail login process. To log in with a different account you have to delete the created volume or the files in it.

To update the running container to the latest version of the selected tag run

docker-compose pull
docker-compose up -d

Install as package

1. Install Git, Python>=3.9 and pip
2. Run pip install git+https://github.com/Der-Henning/tgtg
3. Create config.ini as described in the Wiki
4. Start scanner with python -m tgtg_scanner

To update to the latest release run pip install --upgrade git+https://github.com/Der-Henning/tgtg.

If you receive the ModuleNotFoundError: No module named '_ctypes' you may need to install libffi-dev.

Run from source

Method for advanced usage.

1. Install Git, Python>=3.9 and poetry
2. Clone the repository git clone https://github.com/Der-Henning/tgtg
3. Enter repository folder cd tgtg
4. Run poetry install --without test,build
5. Create config file cp config.sample.ini config.ini
6. Modify config.ini as described in the Wiki
7. Run poetry run scanner

Alternatively, you can use environment variables as described in the wiki. The scanner will look for environment variables if no config.ini is present.

To update to the latest release run git pull.

If you receive the ModuleNotFoundError: No module named '_ctypes' you may need to install libffi-dev.

Build your own binary

You could also build your own binary for your OS/Arch combination.

1. Clone the repository as described above
2. Run poetry install --without test
3. Run make executable

You will find the bundled binary including the config.ini in the ./dist directory.

Usage

When the scanner is started it will first try to log in to your TGTG account. Similar to logging in to the TGTG app, you have to click on the link sent to you by mail. This won't work on your mobile phone if you have installed the TGTG app, so you have to check your mailbox on your PC.

After a successful login, the scanner will send a test notification on all configured notifiers. If you don't receive any notifications, please check your configuration.

Helper functions

The executable or the tgtg_scanner/__main__.py contains some useful helper functions that can be accessed via optional command line arguments. Running scanner[.exe] --help, poetry run scanner --help, python tgtg_scanner/__main__.py --help or python -m tgtg_scanner --help displays the available commands.

usage: scanner [-h] [-v] [-d] [-c config_file] [-l log_file] [-t | -f | -F | -a item_id [item_id ...] | -r item_id [item_id ...] | -R] [-j | -J] [--base_url BASE_URL]

Notifications for Too Good To Go

options:
  -h, --help            show this help message and exit
  -v, --version         show program's version number and exit
  -d, --debug           activate debugging mode
  -c config_file, --config config_file
                        path to config file (default: config.ini)
  -l log_file, --log_file log_file
                        path to log file (default: scanner.log)
  -t, --tokens          display your current access tokens and exit
  -f, --favorites       display your favorites and exit
  -F, --favorite_ids    display the item ids of your favorites and exit
  -a item_id [item_id ...], --add item_id [item_id ...]
                        add item ids to favorites and exit
  -r item_id [item_id ...], --remove item_id [item_id ...]
                        remove item ids from favorites and exit
  -R, --remove_all      remove all favorites and exit
  -j, --json            output as plain json
  -J, --json_pretty     output as pretty json
  --base_url BASE_URL   Overwrite TGTG API URL for testing

Example (Unix only):

poetry run scanner -f -J >> items.json

Creates a formatted JSON file containing all your favorite items and their available information.

Metrics

Enabling the metrics option will expose an HTTP server on the specified port supplying the currently available items. You can scrape the data with Prometheus to create and visualize historic data or use it with your home automation.

Scrape config:

- job_name: 'TGTG'
  scrape_interval: 1m
  scheme: http
  metrics_path: /
  static_configs:
  - targets:
    - 'localhost:8000'

Development

For development, I recommend using docker.

If you are developing with VSCode, you can open the project in the configured development container including all required dependencies.

Alternatively, install all required development environment dependencies, including linting, testing, and building by executing

make install

For developement and testing it is sometimes useful to trigger TGTG Magic Bag events. For this purpose you can run the TGTG dev API proxy server. The proxy redirects all requests to the official TGTG API server. The responses from the item endpoint are modified by randomizing the amount of available magic bags.

make server

Makefile commands

• make install installs development dependencies and pre-commit hooks
• make server starts TGTG dev API proxy server
• make start runs the scanner with debugging and using the API proxy
• make test runs unit tests
• make lint run pre-commit hooks including linting and code checks
• make executable creates a bundled executable in /dist
• make images builds docker images with tag tgtg-scanner:latest and tgtg-scanner:latest-alpine

Creating new notifiers

Feel free to create and contribute new notifiers for other services and endpoints. You can use an existing notifier as a template or build upon the webhook notifier. E.g. see the ifttt notifier.
