Control: LED Strip Control Software

LED Strip Control

Software:

So ssh into your pi or whatever your server may be.

The first thing we are going to do is create the LED Strip items.

So type in sudo nano /etc/openhab2/items/home.items and press enter, you may need to type in admin password.

Type in:

//LED Strip Control

Group MKLEDStripControl1Group "Desk LED Strip" (All)

Color MKLEDStripControl1Color "Desk LED Strip" <colorpicker> (MKLEDStripControl1Group) [ "Lighting" ]

String MKLEDStripControl1String "Desk LED Strip" (MKLEDStripControl1Group) {mqtt=">[broker:MK-SmartHouse/lights/MK-LEDStripControl1:command:*:default]"}

Dimmer MKLEDStripControl1Speed "Desk LED Strip Speed" <time> (MKLEDStripControl1Group) {mqtt=">[broker:MK-SmartHouse/lights/MK-LEDStripControl1:command:*:default],<[broker:MK-SmartHouse/lights/MK-LEDStripControl1/state/speed:state:default]", autoupdate="false"}

String MKLEDStripControl1Effect "Desk LED Strip Effects" <rgb> (MKLEDStripControl1Group) {mqtt=">[broker:MK-SmartHouse/lights/MK-LEDStripControl1:command:*:default],<[broker:MK-SmartHouse/lights/MK-LEDStripControl1/state/effect:state:default]", autoupdate="false"}

And press enter.

Now press control x then y and enter.

Next up is the sitemap file so we can control the device.

Type in sudo nano /etc/openhab2/sitemaps/home.sitemap and press enter. It will bring up the sitemap. If you are following along with my series then we have many different frames in our sitemap. I am going to put the device in the frame called MK-Room. So go to the frame and type in:

Colorpicker item=MKLEDStripControl1Color

Selection item=MKLEDStripControl1Effect mappings=["NONE"="NONE", "FADE"="FADE", "POLICE"="POLICE", "COLD"="COLD", "WARM"="WARM", "BREATH"="BREATH", "RAINBOW"="RAINBOW"]

Slider item=MKLEDStripControl1Speed

and press enter

Now press control x then y and enter.

There is one more thing we have to do and that is make a rule where it will convert the color picker into MQTT the device can understand.

In terminal type in sudo nano /etc/openhab2/rules/home.rules and press enter. At the top of the file type in

var HSBType hsbValue

var int redValue

var int greenValue

var int blueValue

var String RGBvalues

These are the variables the rules will be manipulating.

In the bottom of the file type in:

rule "MKLEDStripControl1"

when

Item MKLEDStripControl1Color changed

then

hsbValue = MKLEDStripControl1Color.state as HSBType

redValue = hsbValue.red.intValue

greenValue = hsbValue.green.intValue

blueValue = hsbValue.blue.intValue

RGBvalues= redValue.toString + ";" + greenValue.toString + ";" + blueValue.toString + ";"

sendCommand(MKLEDStripControl1String, RGBvalues)

logInfo("MKLEDStripControl1Color", RGBvalues )

end

What these rules do is take the values from the colorpicker and send them through MQTT.

Great! Now press control x then y and enter.

sudo systemctl restart openhab2.service
