[Plugin] - Device Updates

[getSurreal]

@Dnpwwo has a nice little function in his examples for only updating devices when there is something different. This is a great idea, but for devices that may go a while without anything changing, they will go offline. Here's a small update to that function which will make an update before the sensor timeout is reached.

Code: Select all

from datetime import datetime
import time

Code: Select all

def UpdateDevice(Unit, nValue, sValue):
    # Make sure that the Domoticz device still exists (they can be deleted) before updating it
    if (Unit in Devices):
        # Update the device before it times out even if the values are the same
        SensorTimeout = Settings['SensorTimeout']

        # try/catch due to http://bugs.python.org/issue27400
        try:
            timeDiff = datetime.now() - datetime.strptime(Devices[Unit].LastUpdate,'%Y-%m-%d %H:%M:%S')
        except TypeError:
            timeDiff = datetime.now() - datetime(*(time.strptime(Devices[Unit].LastUpdate,'%Y-%m-%d %H:%M:%S')[0:6]))

        timeDiffMinutes = (timeDiff.seconds/60)%60
        if (Devices[Unit].nValue != nValue) or (Devices[Unit].sValue != sValue or timeDiffMinutes+5 > int(SensorTimeout)):
            Devices[Unit].Update(nValue=nValue, sValue=str(sValue))
            Domoticz.Log("Update "+str(nValue)+":'"+str(sValue)+"' ("+Devices[Unit].Name+")")
    return
