Overview
This is my last post for the Home Automation Project14 event due to time constraints. My intention was to implement controlling the GPIO connections from P2 on the MATRIX Creator via openHAB, but that is not quite working at this point, so I am moving to just the Everloop control which I already have configured in openHAB. This control from openHAB is from the Exec Binding calling python scripts using the matrix-lite-py interfaces. The Basic UI is used from openHAB to send the commands to the MATRIX Creator.

MATRIX Lite Python
Using the example that came with the MATRIX Lite Python interfaces, I have created a couple of methods that can turn on and off the Everloop LEDs as well as control the color and brightness.
Python Script uses a Dictionary to sed specific colors.
ledMatrix = {'red': {'ledr' : 1, 'ledg' : 0 , 'ledb' : 0, 'ledw' : 0},
'green': {'ledr' : 0, 'ledg' : 1 , 'ledb' : 0, 'ledw' : 0},
'blue': {'ledr' : 0, 'ledg' : 0 , 'ledb' : 1, 'ledw' : 0},
'white': {'ledr' : 0, 'ledg' : 0 , 'ledb' : 0, 'ledw' : 1},
'off': {'ledr' : 0, 'ledg' : 0 , 'ledb' : 0, 'ledw' : 0},
'on': {'ledr' : 1, 'ledg' : 1 , 'ledb' : 1, 'ledw' : 1}
}
## LED Example ##
def runEverloop(self, color):
self.everloop = hal.everloop()
color = color.lower()
print ("Color: %s" % color)
for i in range(self.everloop.ledCount):
#led = hal.led(0,0,0,0)#led.r led.g led.b led.w
led = hal.led(ledMatrix.get(color, {}).get('ledr'),
ledMatrix.get(color, {}).get('ledg'),
ledMatrix.get(color, {}).get('ledb'),
ledMatrix.get(color, {}).get('ledw'),
)#led.r led.g led.b led.w
self.leds.append(led)
del led
self.everloop.set(self.leds)
Python method to dynamically set LED colors:
## LED Color set ##
def setEverloop(self, colorVal):
self.everloop = hal.everloop()
print ("Color: %s" % colorVal)
colorList = colorVal.split(":")
for i in range(self.everloop.ledCount):
#led = hal.led(0,0,0,0)#led.r led.g led.b led.w
led = hal.led(int(colorList[0], 16),
int(colorList[1], 16),
int(colorList[2], 16),
int(colorList[3], 16)
)#led.r led.g led.b led.w
self.leds.append(led)
del led
del colorList
self.everloop.set(self.leds)
Sorry, I am not sure what is happening with the formatting of the code but I do not have time to fix they way the code looks.

Well, that is about it. This has been interesting, and as always I wished I had more time to get more done, but I at least I was able to this much configured. There is still a whole host of things that can be done with this config and I will continue to work with it. I'd like to thank Tariq and element14 for providing me with the MATRIX Creator and Raspberry Pi 3 A+ for the project.
