Power Data Log

Modbus Values to pull at 60 min intervals to a log file co-located with the video data. This log file could sit in the same directory as all the daily video data folders (/media/pi/external_storage). Each log entry should have the Pi's hardware clock value associated with it as the MPPT charge controller does not have an accurate clock.

Pi Hardware Clock Value
SunSaver MPPT Battery Voltage (V)
SunSaver MPPT Array Voltage (V)
SunSaver MPPT Load Voltage (V)
SunSaver MPPT Charge Current (A)
SunSaver MPPT Load Current (A)
SunSaver MPPT RTS Temperature (deg C)
SunSaver MPPT Ambient Temperature
MPPT Temp
SunSaver MPPT Charge State ()
SunSaver MPPT Ah Charge(Daily) (Ah)
SunSaver MPPT Ah Load(Daily) (Ah)
SunSaver MPPT Alarm (Daily)

Modbus Values to pull at 12 hour intervals to a log file in ~/dencam. Each log entry should have the Pi's hardware clock value associated with it as the MPPT charge controller does not have an accurate clock.

Pi Hardware Clock Value
SunSaver MPPT Battery Voltage (V)

Hi BJ,
Was just wondering if it would be acceptable to store the hourly MPPT values into one giant csv file rather than having it separated by days

Hi BJ,

You said you were using a cronjob to reboot the dencam each day at 1am, Im updating the readme right now to include the cronjobs we have set up for the SunSaver and was hoping you could send over the comman you're using for that cronjob so i could include it while im at it.
