Upcycled Clock- Unleash the power using IFTTT

Here is a quick and easy way to get your Intel Edison connected to the Internet !! using the simple python program below to connect to IFTTT.

If you have been living under a rock and not heard about IFTTT, here is a quick intro from Wikipedia - IFTTT (If This Than That)is a free web-based service that people use to create chains of simple conditional statements, called applets. An applet is triggered by changes that occur within other web services such as Gmail, Facebook, Instagram, or Pinterest. An applet may send an e-mail message if the user tweets using a hashtag or to copy a photo on Facebook to a user's archive if someone tags a user in a photo.

In my scenario, the applet is triggered by the python code below and data is posted to the IFTTT maker channel, this basically is the IF side of things.And, as part of the data send you can send sensor values as part of the payload , which in case of the program below is Temperature, Light value and the potentiometer value. And as part of THEN side of things you can basically trigger various things like -

• Send an email to your self with the sensor values.
• Send your self a text message if the temperature in your home is to high
• Turn on the lights in your house when it gets dark, in my case the idea is to turn on the Phillips Hue Lights.
• And, in addition I have also setup another recipe to cycle through various colors of the Hue bulb, which I am calling party mode

<i will post a short video of the setup over the weekend>

To create a new recipe to send sensor values from the the Edison via an email when the python program below is triggered, click the new applet button and follow the steps as shown in the screenshots below

Here is the python program to trigger the IF side of things aka the Maker webhooks,

#!/usr/bin/python
# Create by Carmelito to send sensor data to IFTTT so that you work your magic,this is based on
# Grove Light sensor https://github.com/intel-iot-devkit/upm/blob/master/examples/python/grovelight.py
# Grove Temp https://github.com/intel-iot-devkit/upm/blob/master/examples/python/grovetemp.py
# Grove Pot https://github.com/intel-iot-devkit/upm/blob/master/examples/python/groverotary.py
import requests
from time import sleep
from upm import pyupm_grove as grove

#get the api key from Maker Webhooks channel https://ifttt.com/services/maker_webhooks/settings
#example URL https://maker.ifttt.com/use/xxxxxxxxxxxxxxxxxxxxx
api_key = 'xxxxxxxxxxxxxxxxxxxxx'
event = 'from_edison'
#Grove Pot connected to connected A0 on the Grove shield
potSensor= grove.GroveRotary(0)
#Grove Temperature sensor connected A1
tempSensor = grove.GroveTemp(1)
#Grove Light sensor connected A2
lightSensor = grove.GroveLight(2)

def send_IFTTT_event(api_key, event, temp=None, lightValue=None, potValue= None):
    #posting data to IFTTT
    url = "https://maker.ifttt.com/trigger/{e}/with/key/{k}/".format(e=event,k=api_key)
    payload = {'value1': temp, 'value2': lightValue, 'value3': potValue}
    try:
        requests.post(url, data=payload)
    except requests.exceptions.RequestException as resp:
        print("Error from IFTTT: {e}".format(e=resp))

def main():
    temp = '0'
    lightValue = '00'
    #Getting Pot value
    potValue = potSensor.abs_value()
    print("Pot value: " + str(abs))
    sleep(1)
    #Getting grove temperature value
    print(tempSensor.name())
    for i in range(0, 10):
        celsius = tempSensor.value()
        fahrenheit = celsius * 9.0/5.0 + 32.0;
        print("%d degrees Celsius, or %d degrees Fahrenheit" \
                 % (celsius, fahrenheit))
    temp = fahrenheit
    #Getting light sensor value
    print(lightSensor.name() + " raw value is %d" % lightSensor.raw_value() + \
    ", which is roughly %d" % lightSensor.value() + " lux");
    lightValue = lightSensor.raw_value()
    sleep(1)

    send_IFTTT_event(api_key, event, temp, lightValue, potValue)

if __name__ == "__main__":
    main()

As part of the code replace the api_key with your key, which you will find at  https://ifttt.com/services/maker_webhooks/settings

Here is the sample email recived once the program run

On the similar lines, you can setup more recipes on IFTTT to trigger as shown in the screenshot below. For the Hue setup you will have to register your Hue bridge online or via the Phillips hue app on your phone.
