Possible Error
Miguel Fonseca
I'm trying to implement a schedule that will run all day and have ON time and OFF time. So I wan't a method to be called with state 1 keeps in state 1 for a period and them call the same method with state 0 and keep for another period. So basically a Lamp will turn ON for 1 minute and them will be OFF for 4 minutes, always switching between states. I already try changing/modifying the job, with Interval and Cron, they all gave me same problems. So the problem is that it will run flawless for hours and them fail to fired the event once or twice. Sometimes it just don't trigger. The Log doesn't show nothing.
I made a simple snippet just for testing:
import time
import logging
from apscheduler.schedulers.background import BackgroundScheduler
from apscheduler.events import EVENT_JOB_ERROR, EVENT_JOB_EXECUTED
from datetime import datetime
LOG_LEVEL = logging.INFO
LOG_FILE = "/var/log/test.log"
LOG_FORMAT = "%(asctime)s %(levelname)s %(message)s"
logging.basicConfig(filename=LOG_FILE, format=LOG_FORMAT, level=LOG_LEVEL)
def rele(on, off, state):
print(str(datetime.now()) + ': ' + str(state))
state = str(1 - int(state))
return on + ',' + off + ',' + state
def my_listener(event):
if(event.exception):
print('The job crashed: ' + event.job_id)
else:
splited = event.retval.split(',')
jobid = event.job_id
sched.remove_job(event.job_id)
period = 1
if(splited[2] == '0'):
period = int(splited[0])
else:
period = int(splited[1])
sched.add_job(rele, 'interval', minutes=period, args=[splited[0], splited[1], splited[2]], id=jobid, misfire_grace_time=None)
sched = BackgroundScheduler(daemon=True)
sched.add_listener(my_listener, EVENT_JOB_EXECUTED | EVENT_JOB_ERROR)
sched.add_job(rele, 'interval', minutes=1, args=['1', '4', '1'], id='rele1', misfire_grace_time=None)
sched.start()
print(str(datetime.now()) + ": start")
while(True):
time.sleep(.1)
And the Log is:

I'm running this is a Raspberry Pi 3 with Python 2.7.
Thank you in advance.

Have you tried logging with the logging.DEBUG level?
I must say that constantly removing and adding jobs is not the intended usage pattern with APScheduler.
Why not have two jobs: one that turns on the lamp and one that
turns it off, running on different schedules?
