Calling get_realtime() doesn't seem to update data without re-authentication

[addohm]

In some abbreviated testing of this package, I'm finding that the get_realtime() function doesn't actually update the data without re-authentication, regardless of how often I call it.

modified sense_api.py

import json
import sys
from time import time
from datetime import datetime

from .sense_exceptions import *

API_URL = 'https://api.sense.com/apiservice/api/v1/'
WS_URL = "wss://clientrt.sense.com/monitors/%s/realtimefeed?access_token=%s"
API_TIMEOUT = 5
WSS_TIMEOUT = 5
RATE_LIMIT = 60

# for the last hour, day, week, month, or year
valid_scales = ['HOUR', 'DAY', 'WEEK', 'MONTH', 'YEAR']


class SenseableBase(object):

    def __init__(self, username=None, password=None,
                 api_timeout=API_TIMEOUT, wss_timeout=WSS_TIMEOUT, rate_limit=RATE_LIMIT):

        # Timeout instance variables
        self.api_timeout = api_timeout
        self.wss_timeout = wss_timeout
        self.rate_limit = rate_limit
...

test_script.py

import time
from sense_energy import Senseable

REFRESH_RATE = 30

if __name__ == '__main__':
    sense = Senseable(rate_limit=REFRESH_RATE)
    sense.authenticate('addohm@gmail.com', 'Bms#22540')
    while True:
        sense.update_realtime()
        print ("Real time consumption:", sense.active_power, "W")
        print ("Real time production:", sense.active_solar_power, "W")
        time.sleep(REFRESH_RATE)
