from firebase import firebase
from firebase_token_generator import create_token
from apscheduler.schedulers.blocking import BlockingScheduler
 
class AIHome:
 
def __init__(self, onTime, offTime):
 
self.onTime=onTime
self.offTime=offTime
self.updateInterval = 6
self.webPush = False
self.relayStatesA = []
self.relayStatesD = {}
logging.basicConfig()
#Call fetchUpdate every 6 hours
 
print('initting AIHome...scheduling job')
sched = BlockingScheduler()
@sched.scheduled_job('interval', hours=1)
def timed_job():
print('This job runs every 6 hrs. timed_job gets called or something else')
#call fetchUpdate()
self.fetchUpdate();
 
sched.configure()
#options_from_ini_file
sched.start()
