Trying to replace Python with NodeJS?

[b3ck]

I know this may not be the place to ask this question, but I figured someone here might be able to help, so I’m using a python script that came with my UPS:

#!/usr/bin/env python
import struct
import smbus
import sys
import time


def readCapacity(bus):

     address = 0x36
     read = bus.read_word_data(address, 4)
     swapped = struct.unpack("<H", struct.pack(">H", read))[0]
     capacity = swapped/256
     return capacity


bus = smbus.SMBus(1) # 0 = /dev/i2c-0 (port I2C0), 1 = /dev/i2c-1 (port I2C1)

while True:

 print "******************"
 print "Battery:%5i%%" % readCapacity(bus)

 if readCapacity(bus) == 100:

         print "Battery FULL"

 if readCapacity(bus) < 20:


         print "Battery LOW"
 print "******************"
 time.sleep(2)

And I have a NodeJS app, in this app I have this code:

  try {
    let socVoltage = fs.readFileSync('/sys/bus/i2c/drivers/ina3221x/6-0040/iio:device0/in_voltage0_input', 'utf8');
    socVoltage = parseInt(socVoltage) / 1000.0;
    socVoltage = `${socVoltage.toFixed(3)} V`;
    sensors['Voltage'] = socVoltage;
  } catch(err) {};

Is there a way I can get what the Python script is getting for capacity into my NodeJS app in a similar way? I’m basically trying to not use python and just let my NodeJS app handle it.

Thanks in advance,

Would you might to share how to resolve? Thanks

Yes I will, it’s for a much bigger project that will be posted on GitHub, I’ll link here once it’s done 😁👍
