(начинающий программист Python в лучшем случае здесь ..)
Я использую модуль для доступа к системе автоматизации здания под названием BAC0 .Сценарий создает устройство автоматизации здания из моего ноутбука Windows, когда он запускается для связи BACnet с системой автоматизации здания через локальную сеть Wi-Fi для получения данных.
В частности, этот сценарий ниже опрашивает контроллер горячей воды.для датчика температуры на выходе каждые 120 секунд, а затем обновляется каждые 600 в цикле while True.
import BAC0
import time
#alarm setpoint
setPoint = 140
#connect to device
bacnet = BAC0.lite()
hws = BAC0.device('100:99', 30099, bacnet, poll=120, history_size=10000)
while True:
data = hws['SHWS-T']
time.sleep(600)
if data > setPoint:
good = f'[INFO] - Looks good, the temp of the {data} on {time.ctime()}'
print(good)
else:
bad = f'[INFO] - Looks bad, the temp of the {data} on {time.ctime()}'
print(bad)
print("Here's the coldest last 10 recorded boiler supply temp readings")
print(data.history.nsmallest(n=10, keep='last'))
print("I better get some help!")
В любом случае, то, что происходит время от времени, - контроллер не отвечает, а затем сценарииостанавливается, потому что если это ... И было бы замечательно, если бы я знал, как сделать retry
повторение 3 раза, а затем просто pass
, чтобы подождать еще 600 секунд, чтобы повторить попытку ...
Я знаю, что это не правильно ниже, но что-то вроде этого ???
try:
if isinstance(Exception: Problem reading : SHWS-T)
# retry function?
retry()
else:
# This is our sensor value
pass
