My hacks integrating an EcoFlow Delta Pro into my systems management tools

My EcoFlow Delta Pro Hacks

Log selected Delta Pro metrics into a MariaDB database and control AC vs solar battery charging

• ecoflow-logger Python script that uses:
  • ecoflow.py EcoFlow API module adapted from the vwt12eh8/hassio-ecoflow GitHub project
  • smartthings.py SmartThings API module
  • ecoflow-logger.timer Systemd timer that triggers ecoflow-logger.service once a minute
  • ecoflow-logger.service Systemd service file that executes the ecoflow-logger script

The ecoflow.py API module uses the reactivex module which is not available in the Fedora repositories I use. I use the following commands to create a virtual Python environment in which to run this script:

cd /opt/ecoflow 
python -m venv ecoflow-python
/opt/ecoflow/ecoflow-python/bin/pip install reactivex requests PyMySQL mysqlclient

The logger script can now be run with this command:

/opt/ecoflow/ecoflow-python/bin/python /opt/ecoflow/ecoflow-logger

Show the status of the Delta Pro on a Nagios dashboard

A Nagios plugin for the Delta Pro that queries the MariaDB database for status:
