Let’s create our first trigger. We’ll create a trigger to turn on our light when the temperature reaches a certain value.

1. To begin creating a Trigger, open the up the feature by selecting Alerts & Triggers in the navigation menu.

2. Click the New Trigger button to start creating a new trigger.

3. The Create Trigger screen appears.

From here, you can fill in all the details required for creation of your trigger. When creating a new trigger, the empty screen serves as an overview of the creation process. To make this process easy, you will be guided through trigger creation that is easy to follow and select the devices and actions that you want.

Example: IF my device senses something, THEN do something in response.

1. Let’s begin by giving our trigger a name. Enter “Temp High, Turn on Light” into the Trigger Name field.

2. We’re going to trigger when our temperature sensor does something. The Temperature sensor is located on our RaspberryPi device, so drag & drop the RaspberryPi device into the IF statement.

3. After selecting the Temperature sensor, we can choose whether we want to trigger an action if temperature is above or below a certain value. We want to react to the temperature being high, so we select the Temperature from the list and select Temperature Above in the options presented.

4. We want to take action once the temperature is high by turning on our light. Out Light is also located on the RaspberryPi device, so drag & drop that device into the THEN statement area.

5. We can now choose an action to take on RaspberryPi. Since we want to turn on the light, select LightSwitch from the actions list and then choose On from the list of options available.

6. We’re done! Click Save Trigger to complete our trigger and return to the Triggers list where our new trigger is shown.

7. Cayenne will automatically synchronize the trigger with the Pi and will now start monitoring the temperature sensor and when it reaches the correct temperature your trigger will automatically run.

The post Setting up your first Trigger appeared first on myDevices Cayenne.

1. From the online dashboard, locate the Add new menu and select the Device entry.

2. On the Add Device screen you will see categories containing various sensors and devices that can be added. The switch that we want to add is located in the Actuators category. Since we want to add a light switch, locate the Light tile and click on it to continue.

3. From the list of Light devices that appears, find and click on the Light Switch tile.

4. In order to add our new light switch widget to the dashboard, we will need to fill in a few details first.

Name: Enter “Light Switch” for the name of our new widget.
Icon: Select the Light icon from the list of icons.
GPIO: Our LED is connected directly to the Raspberry Pi, so make sure the Integrated GPIO is selected in the GPIO list.
Channel: When setting up our LED we wired the light to GPIO 17. Select 17 in the list of channels
Invert Logic: We want the light to start off and then turn on as we activate the button, so make sure that the Invert Logic is set to No.

6. Click Add Sensor to complete adding your switch. You will then be returned to the Dashboard where you will see your new switch added.

Step 1: Connect the LED positive wire (the longer of the two wires) from resistor to a GPIO pin. In this example, GPIO 17.

Step 2: Connect the LED ground wire (the shorter of the two wires) to the GND pin from the Pi Cobbler

1. Make sure Raspberry Pi is powered off when connecting wires.
2. When using a GPIO ribbon cable, make sure the power wire (it’s a different color than the others) is connected to the corner of your Raspberry Pi and the top of your Pi cobbler.
3. The provided diagram is just an example of how to connect the sensor. There are many ways to connect sensors and extensions, so try what works best for you!
4. Some full-size breadboards (used in diagrams below) have a powerline that is separated in the middle. If this is the case, be sure your sensors are connected on the same half of the breadboard as your Pi Cobbler.

The Value Display widget we chose when setting up our dashboard allows us to see the latest temperature value directly on the dashboard. Cayenne will constantly update this value as new sensor data arrives.

Let’s try it out! Open the dashboard so that the Temperature sensor is displaying and then hold your hand on the BMP180 sensor. The temperature value updates as soon as a change in temperature is received.

1. From the online dashboard, locate the Add new menu and select the Device entry.

2. From the Add Device screen, click on the Temperature category in the list device types shown under Sensors.

3. After selecting Temperature, a list of temperature sensors will appear. Find the BMP180 sensor and click on it.

Pro Tip: If you know the exact part number or device name of the device you want to add, you can enter this information into the search field to quickly find it.

4. In order to add our new sensor widget to the dashboard, we will need to fill in a few details first.

Name: Enter “Temperature” for the name of our new widget.
Widget: Select the Value Display widget from the list of widget display types.
Icon: Select the Thermometer icon from the list of icons.
Altitude: Enter the current altitude where the device is.

5. Click Add Sensor and your new temperature sensor widget will be added to the dashboard. You will be returned to your dashboard and your new Temperature sensor will appear there.

Step 1: Connect the 3 volt power from your Pi Cobbler to the power line on your breadboard.

Step 2: Connect BMP180 VIN pin to the power line on your breadboard.

Step 3: Connect the ground pin from your Pi Cobbler to the ground line on your breadboard.

Step 4: Connect BMP180 GND pin to the ground line on your breadboard.

Step 5: Connect SCL pin from BMP180 to SCL pin on Pi Cobbler

Step 6: Connect SDA pin from BMP180 to SDA pin on Pi Cobbler

Step 7: Double check wiring, power Pi back on, and add the BMP180 sensor to your dashboard!
