Thanks Ajay for reviewing the architecture and improvements.

Thanks Himanshu And Tech Primers

Which Database you would recommend for storing events or alarms from the IoT device ?

[@ksatya2753]

Nice, is this architecture good for moving devices ? E.g. i want to read location of any car ? can you tell me any small projects links which i can see and implement ? Also tell me which technologies can be used to develop this kind of gadgets and devices which can send notifications.

[@saratchandra4689]

Nice. I don't know that, there are libraries to interact with google assistant. If possible can u pls share, rasberry pi details & how raspberry pi interacts with AC.

Good initiative. More expecting form you. Thanks

[@TechPrimers]

Sure Sujith👍

[@codegeek8256]

Can you please make a video tutorial on how you made your intro animations, or just give us pointers on how we can achieve similar thing.

[@jagadeshdevarajan9662]

Nice way to go!

[@TechPrimers]

Cheers

[@PavanKumar-yj8fu]

Very good information, thank you!!

[@saravanprathi6956]

Interesting video!

How does SNS service knows which mobile started the request ? or are we going to send notifications to all registered mobiles ?

[@TechPrimers]

Good question Manoj. This is where the Metadata in dynamo will help in pushing the response into the right device. However i still feel using websockets could make this communication much effective than the SNS model

[@manojBadam]

@@TechPrimers got it, i thought metadata in dynamo is just for registering the external iot devices.

[@Duskk0077]

why we dont make local arch similar to this one, its more private and quicker because the requests dont have to go to internet

[@manojBadam]

This will be pretty similar to slack chatbot model, may be using aws chatbot service along with lambda would simplify the apigateway and sqs setup.

[@TechPrimers]

Yes for the integration with alexa/ Google assistant. But for the app based trigger we might still need to expose the API gateway. I did not show the app since i thought most ppl use that and it's pretty common.

[@JaNaMSoNi]

I have created home automation projects 3-4 years ago using elastic beanstalk Java and Arduino 😂

[@TechPrimers]

Awesome. Time to upgrade it to use AWS services 🤓😛

[@irfanmuneer3083]

Very difficult to understand. Not a simple step to step process. Please post for video for some one who like to start the journey
