Configuration and user control files

./relay_config.json

• this file will set status of the processes: PH up, PH Down, and PH Monitoring, this file can be modified directly but serves as a file that allows for user controls

./system/relay-control.service

• this file runs the relay-control script as a service file on linux OS
• systemctl enable ~/relay-control/system/relay-control.service
• systemctl start relay-control

./logs/*

• logs of the process as well as status operations

Issues

• MQTT communication for UI control

resolved

• Service file
• json files for api
• Logging over print statements (log files)
• Turn this into a class structure for replicability/ abstraction (objectify)
• Nonblocking starting functionality for module
• error handling
• add liscence
