JBD BMS BTLE Python Script

A Python script that pulls data from the JBD BMS commonly used for LiFePO4 batteries. The script borrows the data extraction and processing from this repo but has been modified to add the data to a postgres database instead of sending it over MQTT. In my case I'm running my MQTT broker on the same Raspberry Pi so the MQTT is unecessary.

# this script will run every minute forever

more info about setting up CRONjobs can be found here.
