Indoor and outdoor motion detector activate the same lamp

Use case

Your customer would like to activate the same lamp with both an indoor and an outdoor motion detector. Every movement detected by one of the detectors will switch on the lamp for 1 minute, independent of the current lamp status.

E.g.

Movement is detected by the outdoor motion detector. The lamp is switched on for 1 minute.
59 seconds later a new movement is detected by the indoor motion detector. The lamp is again activated for 1 minute.
The following minute no new movement is detected. The lamp is finally turned off. In total the lamp was activated for 1 min 59 sec.

Procedure

Creating the controls and the devices

Create an indoor motion detector (DET1).
Create an outdoor motion detector (DET2).
Create a lamp (LAMP1).
Create the virtual devices (VIRT1 and VIRT2).

Creating the routines

Create a routine Motion detection with indoor detector(s) (ROUT1).
- Configure the following behaviour:
  - master detector that initiates the routine: indoor motion detector (DET1)
  - device that is switched on when the routine is started: VIRT1: Value = true
- Set the parameter switch-off delay to 1 min
Create a routine Motion detection with outdoor detector(s) (ROUT2).
- Configure the following behaviour:
  - master detector that initiates the routine: outdoor motion detector (DET2)
  - device that is switched on when the routine is started:VIRT2: Value = true
- Set the parameter switch-off delay to 1 min

Creating the condition

Create a condition (COND1) for turning on the lamp when one of the detectors detects movement. Use the following logic:

IF (ROUT1: State = motion detected + switch-off delay) or (ROUT2: State = motion detected + switch-off delay)
THEN LAMP1: Value = on
ELSE LAMP1: Value = off

The switch-off delay parameter that is set on the motion detectors makes sure that the condition is "true" for 1 minute. In this way the lamp is only turned off when both detectors don't detect any movement for at least 1 minute.

Filling the cabinet and addressing the device

Fill the cabinet with ...	and address the following device ...
a switching module (3x) 2U (MOD1)	lamp LAMP1.
