AWS IoT Greengrass v2 (Part 5) Working with Shadows & Shadow Manager Component raspberry pi iot

***Comment for suggestions for future videos***

In this video I demonstrate how to use the AWS IoT Shadows concept to report status and control the Red LED on the Raspberry Pi device.

If you have any problems or questions please comment below.

I found this series a HUGE help alongside the very disconnected AWS documentation/tutorials. just seeing someone actually do the things in realtime and figuring out what they need there and then is great, rather than just using the tutorials which seem to always end up with you stopping a step to start following a chain of definitions deeper and deeper till you start to forget what you were even trying to do... so thanks very much for these videos. a year out and they're still really helpful!

Great series! I'd love to see a demonstration on automatic fleet provisioning and Bulk Registration.

Thanks for sharing this. very well-organized tutorial. Help me a lot as a beginner.

You are indeed a lifesaver. I would love to connect with you

Great video to study Gg. Thanks a lot.

Very detail, in-depth, and easy to understand from A-Z on this series. Thank you. Looking forward to your next series. If you can show how to connect Home Assistant to Greengrass, that would be Awesome as the community for Home Assistant is huge. Another suggested Series might be Modbus TCP to greengrass or NodeRed to Greengrass. Thank you.

Are there more videos still coming? this has been very helpful!

Hey your videos are so much helpful for me and my team... Could you please create new video on how can we connect aws IoT greengrass core to aws lambda function.

Great series! I was struggling with Greengrass and AWS workshops to make it work on my Pi, but your series made things so much clearer in no time. There's one thing that I got difficult to understand and make it work. How do you continuously publish data through MQTT to the IoT core for processing or logging in DynamoDB or S3. I got a DHT11 temperature and moisture sensor connected to Pi but I still don't know how to use Streams to push the data to AWS IoT without using callback or sending requests to components. Maybe something you could touch upon in the next video.

Great Explanation. Could you please explain how to connect others device like ESP32 that connect to IoT core trough greengrass core ?

[aacasd]

Can we subscribe to multiple different topics on AWS IoT core?

[dylanatevergreen]

I am struggling to deploy this at scale because the recipe must indicate a specific device name and cannot use a variable. Any ideas?

[vitorsdedeus]

HOw to make it work for unnamed shadows?

[dylanatevergreen]

1. Using nearly exact same setup I still get authorization issues with a named shadow, not sure how to further debug.
2. Can you show how one would update the unnamed shadow? If I just leave shadow name blank will it assume the classic shadow?
