How to read an NFC tag and open your garage

Plain text
step 1:
-------
Install the Trigger and Tasker apps in your phone.

step 2:
-------
In the Tasker app we create a task that will send an HTTP POST request to the Particle Cloud to open or close the garage door.

Please take a look at this thread to see how to enter information in Tasker:
https://community.particle.io/t/solved-using-tasker-for-android-to-post-an-api-request-to-spark-core/4724/17

step 3:
-------
In the Trigger app we will create a task to fire off a task in Tasker. At the end of the task creation, the app will ask us to scan the NFC tag so it can save the task in it.

How to use Google Voice to open your garage

Plain text
step 1:
-------
Install the Autovoice and Tasker apps in your phone.


step 2:
-------
In the Tasker app we create a task that will send an HTTP POST request to the Particle Cloud to open or close the garage door.
Note: if you already created a task to open your garage with an NFC tag, we will use the same task.

Here is what I entered in Tasker:
- create a new Task called "OpenGarage"
- add an Action
- select Net
- select HTTP Post
- enter in Server:Port
      https://api.particle.io/v1/devices/<PARTICLE DEVICE ID>/garage_open
- enter in Data/File
      access_token=<YOUR PARTICLE ACCESS TOKEN>
-note that garage_open is the function we want to trigger with this POST request

Please take a look at this thread to see how to enter information in Tasker:
https://community.particle.io/t/solved-using-tasker-for-android-to-post-an-api-request-to-spark-core/4724/17


step 3:
-------
In the Tasker app we will create a Profile to trigger that task when we speak "open garage". 

Here is what I did in Tasker:
- create a new Profile
- select Event
- select Plugin
- select Autovoice -> Recognized
- tap on Configuration
- tap on Speak Filter
- record your voice command
- choose your voice command from the list
- hit the check at the top then hit back in Tasker
- select the task you want this command to trigger, it should be OpenGarage
- you are done!


You can also follow the instructions on the video in the Google Play page:
https://play.google.com/store/apps/details?id=com.joaomgcd.autovoice&hl=en


step 4 (optional):
------------------

Repeat steps 2 and 3 to create a GarageStatus action and CloseGarage actions in Tasker and the respective voice commands to get a full voice interface to your garage.

step 3:
-------
In the Trigger app we will create a task to fire off a task in Tasker. At the end of the task creation, the app will ask us to scan the NFC tag so it can save the task in it.

Here is what I did in Trigger:
- create new task
- hit next on the "Add one or more triggers" screen
- add an action
- select Tasker -> Tasker Task then next
- hit the magnifier so you can select the task in Tasker
- select OpenGarage and tap on "ADD TO TASK"
- hit Done
- hit NFT in "Add one or more triggers" and Next
- hit done in "Add restrictions" -> Next -> Next -> Done (there is no need for a second, switch task)
- Scan your NFC tag to save the task date in it
- Hit Done on top
- you are finally done
