No shutdown after 120 seconds

[Deleted user]

Setting the "powerSavingDelay" to 120 seconds does not turn off the screen.
Setting to 60 seconds works just fine.

Below config is for 60 seconds delay:

   module: 'MMM-PIR-Sensor',
                        config: {
                                sensorPin: "17",
                                powerSavingDelay: "60",
                                powerSaving: true,
                                relayPin: "27",
                                relayState: "0"
                        }

Is this the case or should 120 seconds (2 minutes) work fine too?
Is this provided?

Thanks
