Positioning of this article

I wrote an article here I made an IFTTT button that unlocks the entrance 2 lock sesame with 1 button (via AWS Lambda). However, it is an article that seems to be able to do such a thing by applying the Lambda function created at that time.

Preceding case

Candy hosue, the publisher of Sesame, published an article in 2018, and I also tried hands-on this once. (The AWS IoT button was bought at that time). However, with the method in this article, only one sesame can be unlocked, so I wanted to unlock two sesame with the touch of a button, so I created the method in this article.

What is an AWS IoT button

This guyis. It is a button that can stimulate IoT 1-Click and Lambda on AWS with the push of a button.

What i did

1. AWS IoT button registration and network connection

Official article

―― 2. Set up the AWS lot 1 click app

All you have to do is follow the steps in.

2. Get API key and Sesame ID for 2 cars

Obtain the API key and sesame ID as described in 1. in the following article.

-I made an IFTTT button that unlocks the entrance 2 lock sesame with one button (via AWS Lambda)

3. Preparation of Lambda function

3-1. Function launch and `pysesame2` upload

Launch the function from AWS Lambda and upgrade the external module pysesame2 as described in 2-1. and 2-2. in the following article.

-I made an IFTTT button that unlocks the entrance 2 lock sesame with one button (via AWS Lambda)

3-2. Writing Python code

Write the following code. It's a Python version, but I wonder if 3.8 is fine.

`lambda_function.py`


from uuid import UUID
from pysesame2 import Sesame
import os

device_id_1 = UUID(os.environ['DEVICE_ID_1'])
device_id_2 = UUID(os.environ['DEVICE_ID_2'])
APIKey = os.environ['APIKEY']
sesame_1 = Sesame(device_id_1, APIKey)
sesame_2 = Sesame(device_id_2, APIKey)

def lambda_handler(event, context):
    sesame_1.async_unlock()
    sesame_2.async_unlock()

After writing the code, write the API key obtained in step 1. and the two sesame IDs one by one in the" environment variable "below it and save it.

3-3. Test

After completing the above, execute the function test from "Test" on the upper right of the screen. The JSON to be poured can be hello world or anything. Success if two sesame are unlocked.

4. Create an IoT 1-Click project and associate buttons with Lambda functions
