Motion Activated Light Using Fibaro Home Center

This application note shows how to create a motion controlled light that automatically turns on for a predefined period during certain times of the day using the Fibaro Home Center central controller.

Project Aim

The aim of this project is to automatically control a light:

Light turns on when motion is detected
Light stays On for 1 minute after the last motion is detected
This system only works during a set period of the day (18.45 and 06.30)

Components

For this project I used a Z-Wave system comprising of:

Fibaro Dimmer module - used to control the light via Z-Wave
Fibaro Motion Detector - used to sense motion in the room
Fibaro Home Center 2 or Home Center Lite (HC Lite) Z-Wave Controllers. - central Z-Wave controller

Z-Wave Devices for motion activated light control

Scene Control

After including the devices into the Fibaro Home Center (HC2 or HCL) controller we will use 'Scenes' to control the behaviour of the sensor and the dimmer it's controlling.

We will need to create four scenes in Home Center (HC):

Light Motion On - turns light On when motion detector sends a 'Breached' (movement) alert
Light Motion Off - turns light Off when motion detector sends a 'Safe' (no movement) alert after a delay of 60 seconds
Active - controls the start time when the scenes become active (18.45)
Inactive - controls the end time when the scenes stop being active (06.30)

Create a Time Variable

Before we create the scenes to control the lights, we need to create a variable that can be used to control the times at which the scenes are active.

Variables are created and edited in HC's Variable Panel.

Go to the Panels tab and select the Variables Panel from left-hand navigation bar
In 'Predefined variables' click 'Add'
Give the new variable a name - for example 'Active'
We need to provide the variable with two predefined values - change Value 1 to 'Active' and Value 2 to 'Inactive'
Click the blue 'Save' button

Creating Variables in HC2

Create the Light Motion On Scene

Scenes are created and edited in HC's Scenes Tab, to create the 'Light Motion On' scene

Go to the Scenes tab and click 'Add Scene' in left-hand navigation bar
Give the new scene a name - for example 'Light Motion On'
Choose a Room from the drop-down list - I selected 'Demo'
Select the 'Active Scene' and 'Start when Home Center starts' boxes

Scene General Tab

Click the 'Advanced' tab and then in 'Add scene using graphic block' click 'Save'
In the black scene box click the '+' icon to add devices and triggers for the scene
From the drop-down menu got to Devices and select the motion detector that will control this scene - for this example it is EVR-SP103
With the EVR_SP103 sensor block in the scene, select 'Breached' from the drop-down menu in the Green condition block
Click the click the '+' icon at the bottom of the black scene box
From the drop-down menu got to Variables and select the 'Active' variable that we created earlier
Make sure 'Active' is selected in the variable's Green block
In the next Orange block change 'And' to 'Then'
Click the click the '+' icon at the bottom of the black scene box
From the drop-down menu got to Devices and select the device to be controlled by the scene - for this example it is Fibaro Dimmer
In the Fibaro Dimmer's Green block set it to 'Turn On', you can also type a brightness level such as 80(%)
Click the grey 'Save' button
That's the main ON scene that will control the light.

Light Motion On Scene

Create the Light Motion Off Scene

This scene is created following the same process as for the 'Light Motion On' scene:

Go to the Scenes tab and click 'Add Scene'
Name the scene 'Light Motion Off' and allocate to a room
Select 'Safe' for the EVR_SP103 sensor condition
Set 60 seconds as the delay period in the EVR_SP103's Red delay block
Select 'Turn Off' for the Fibaro Dimmer's state
Remember to click the grey 'Save' button
Also make sure the 'Active Scene' and 'Start when Home Center 2 starts' boxes are selected in the scene's General tab

Light Motion Off Scene

Create the Active Scene

Go to the Scenes tab and click 'Add Scene'
Give the new scene a name 'Active' and allocate to a room
Select the 'Active Scene' and 'Start when Home Center starts' boxes
Click the 'Advanced' tab and then in 'Add scene using graphic block' click 'Save'
In the black scene box click the '+' icon to add devices and triggers for the scene
From the drop-down menu got to Timers and select 'Days or Week'
Select the days that you would like the scenes to be active - Monday, Tuesday... Sunday
Select 'Exact time' and select the time which you would like the scene to become active - 18.45 for this example
In the Orange block change 'And' to 'Then'
From the drop-down menu got to Variables and select the 'Active'
Make sure 'Active' is selected in the variable's Green block
Click the grey 'Save' button
This scene changes the 'Active' variable's state to 'Active' at 18.45

Active Scene

Create the Inactive Scene

This scene is created following the same process as for the 'Active' scene:

Go to the Scenes tab and click Add Scene
Name the scene 'Inactive' and allocate to a room
Select the same days of the week as the Active scene
Select the time for this scene to start - 06.30 for this example
Select 'Inactive' for the 'Active' variable condition
Remember to click the grey 'Save' button
Also make sure the 'Active Scene' and 'Start when Home Center starts' boxes are selected in the scene's General tab
This scene changes the 'Active' variable's state to 'Inactive' at 06.30

Inactive Scene

We now have the four scenes that enable the lights to be motion activated at different times of the day.
