WifiQR is a small flask app that embeds my wifi password in the form of a QR code into home assistant
This is a simple 1 page app that returns a QR image that is recognised by most mobile devices (both Android an iPhone). Open your camera app, hold your camera in front of the QR image and wait until you are prompted to connect to the WIFI ssid given in the QR.
To run:
pip install flask_wifiqr
export WIFI_PASSWORD="some_password
export WIFI_SSID="some_ssid"data
python -m wifiqr
