Uses cloud watch events to push IoT data from dynamodb to Adafruit IO. I use this on one of my projects to take copy readings that get put into dynamodb by AWS IoT Core from my pollution monitoing device, so that I can graph them in AdaFruit IO (for free).
- A free account on Adafruit.io
- edit lambda_handler.py and replace the values for YOUR_ACCOUNT and YOUR_ADAFRUIT_KEY with the values from your Adafruit account.
- Go create a feed for the item you want to log the data of. In my case I created 2 henc the slighlty weird code in the handler - one for PM25 reading and one for PM10 readings from the pollution sensor and I called my feeds obviously PM25 and PM10. Name yours whatever you want
- Fix the query in the lambda to get whatever data your using in dynamodb
- Check it works with a test (you can also do a curl POST first from your command line to check) something like this: curl -F 'value=WHATEVER_VALUE_YOU_WANT_TO_POST' -H "X-AIO-Key: YOUR_ADAFRUIT_KEY" https://io.adafruit.com/api/v2/YOUR_ACCOUNT/feeds/YOUR_FEED_NAME/data
- Use deploy_to_aws.sh to deploy (remember to edit the name of your function). Note, It has to do the zip because now lambda does not include the Python requests module, so you have to bundle it yourself.
- Create a Cloudwatch event - mines a schedule every 20 minutes
My ddashboard looks like this:
