CMTS CPL Monitor

A project for monitoring LINEAGE J85480S1 power-supplies, involving:

• LINEAGE J85480S1 and its J1 connector
• A Rapberrypi and its GPIO connector
• RPi.GPIO and Flask python libraries
• gunicorn and systemd

Installation (Debian)

Install and configure the web-service

sudo apt-get install python python-dev python-pip git
git clone {repository-url} cmts-cpl-monitor
cd cmts-cpl-monitor
sudo pip install -r requirements.txt
vi config.py         # optionally update with your preferred pinout, or not
python web.py        # test the service with built-in dev web server
curl localhost:5000  # check the web-service output

Install and configure gunicorn

sudo apt-get install gunicorn           # install gunicorn wsgi server
sudo cp `pwd`/systemd.service /etc/systemd/system/cmts-cpl-monitor.service  # create systemd service
sudo systemctl start cmts-cpl-monitor   # start the service
sudo systemctl status cmts-cpl-monitor  # check the service state
curl localhost                          # check the web-service output
sudo systemctl enable cmts-cpl-monitor  # start the service upon boot

Testing with curl

curl localhost[:5000]
