Honey, I'm home!

Always too drunk to text your girlfriend that you got home safe?

This tool will send a message via telegram, once your mobile phone is detected in your wifi network after a couple of hours.

Setup

Install Python 3.7 or higher.
Run pip install -r <PROJECT_ROOT>/requirements.txt on a command line.
You need to find out the MAC address of your phone (or any other device). At usual, this device should be in the same network as the host which runs this application.

Use Telegram's bot BotFather to create a bot: https://t.me/botfather
Follow the instructions given by BotFather and copy the created bot token to a safe place.
Send the message \help to BotFather to check which possibilities of configuration you have.
Enable the setting \setjoingroups.
Create a private Telegram group and add your new bot to the group. Important step!
Find out what's your chat id of the Telegram group. A helper script is placed under tools:
```
python tools/get_chat_id.py -t <YOUR_TOKEN> -g <YOUR_GROUP_NAME>
```

As a last step, create a config file in folder notification named config.json:

{
  "bot_token": "place your token here.",
  "bot_chat_id": "place your chat id here."
}

Run python <PROJECT_ROOT>/phone_detection.py on a command line. You have the following command line options:

Argument	Description	Required	Default
-d / --device	The mac address of the device.	Yes	None
-a / --absence	Send a message when a device is detected that was last seen x minutes ago.	No	60
-s / --scan-interval	Interval in minutes that indicates how often a device search is performed.	No	1
