I’m on the way to migrate my DSL-Rules to SA, but now I’m struggling with the “createTimer”-Function(lambda)

I have the following items(for testing the channels are unlinked and manually switched):

Switch Sonoff_socket_03 "Steckdose RasPi 3b+ [MAP(de.map):%s]"   (gSystem)   // (EG_Buro,gPlugSwitch,gSonoff)   { channel="mqtt:topic:hans:s2003:power"}        
Switch RasPi_online     "Office Pi  [MAP(tech.map):%s]"          (gSystem)   // {channel="network:pingdevice:raspi_office:online"}

The Rule is .py:

from core.rules import rule
from core.triggers import when
from core.date import DateTime
#from core.actions import Transformation
from core.actions import ScriptExecution
T_OFFICEPI_STATUS = None

@rule("raspi_online_monitor_office", description="monitors Office Raspi and switch it off after shutdown", tags=["RasPi", "OfficePi"])
@when("Item RasPi_online changed from ON to OFF")

def office_pi_online(event):
    office_pi_online.log.info("Rule is running")
    if items["Sonoff_socket_03"] == OFF:
        office_pi_online.log.info("Steckdose ist bereits ausgeschaltet")
    else:
        global T_OFFICEPI_STATUS
        office_pi_online.log.info("RasPi Office wird in 3 Minuten ausgeschaltet ")
        if items["Sonoff_socket_03"] == ON:
            if T_OFFICEPI_STATUS is None or T_OFFICEPI_STATUS.hasTerminated():
                T_OFFICEPI_STATUS = ScriptExecution.createTimer(DateTime.now().plusMinutes(3), lambda: events.sendCommand(items["Sonoff_socket_03"], "OFF"))
                office_pi_online.log.info("Timer runs ")
        elif T_OFFICEPI_STATUS is not None and not T_OFFICEPI_STATUS.hasTerminated("TERMINATED"):
            T_OFFICEPI_STATUS.cancel()
            office_pi_online.log.info("Timer cancelled ")

but when the rule is triggered and the “else”-Condition is true, the following error is logged.

If I understand correct, there is something wrong with the “lambda” but I don’t know what and why !!?? :thinking: :thinking:

I used an example from the Docs

'''
    global chargerTimer2
    if items["Outlet9"] == ON and event.itemState <= DecimalType(8) and event.oldItemState <= DecimalType(8):
        if chargerTimer2 is None or chargerTimer2.hasTerminated():
            chargerTimer2 = ScriptExecution.createTimer(DateTime.now().plusMinutes(5), lambda: events.sendCommand("Outlet9","OFF"))
            batteryChargingMonitor2.log.info("Battery charging monitor: Started battery charging turn off timer: Outlet9_Power=[{}], oldItemState=[{}]".format(event.itemState, event.oldItemState))
    elif chargerTimer2 is not None and not chargerTimer2.hasTerminated():
        chargerTimer2.cancel()
        batteryChargingMonitor2.log.info("Battery charging monitor: Cancelled battery charging turn off timer: Outlet9_Power=[{}], oldItemState=[{}]".format(event.itemState, event.oldItemState))
'''

but I do not see what’s the difference.

Any help for a fool ? :wink: :crazy_face:

#1… not T_OFFICEPI_STATUS.hasTerminated

#2… both args need to be str., but what are you doing with the state here, where you need an item name? The items object provides a dictionary of states.

events.sendCommand("Sonoff_socket_03", "OFF")

…mostly the failure sits in front of the screen :upside_down_face: and can’t copy/paste properly either :rofl:

One more question:
Is it possible to log an info when timer ends ?

Thx for your quick reply and help

cheers

If you execute a function in the lambda, then you can do more than one thing. Lambdas in Python can only be one liners.
