This is a simple REST API to access a E3DC system
This script uses a Python library which can be found here: https://github.com/fsantini/python-e3dc and exposes the values as REST API endpoints.
The API uses exposed environment variables to access the E3DC.
- ToDo...
You need to export the variables so the script can read them
# IP address of your local E3DC system
export E3DC_IP_ADDRESS='192.168.1.99'
# username as used to log into the E3DC web portal
export E3DC_USERNAME='use@domain.com'
# password as used to log into the E3DC web portal
export E3DC_PASSWORD='Passw0rd'
# The E3DC RSCP Password (encryption key), as set on the device under Main Page -> Personalize -> User profile -> RSCP password
export E3DC_KEY='secretkey'
# Password to protect e3dc-rest api
export ADMIN_PASSWORD='admin'
Create a self contained environment
python3 -m venv .venv
then you can go into the new made environment and install the requirements
source .venv/bin/activate
pip3 install -r requirements.txt
Dev Webserver:
cd api
python3 api.py
or use
cd api
gunicorn --bind 0.0.0.0:8080 wsgi:app --access-logfile -
