QUESTION
By following this guide Sending commands to devices.
...ANSWER
Answered 2020-Sep-23 at 00:06If you need the device to always receive the payload from IoT Core, even if it was sent while the device is not connected / not responding, you should use configuration instead of a command.
Configuration is persistent in IoT Core, so it will eventually be delivered to the device even if it was non responsive.
Configuration is always sent to the device when it reconnects to IoT Core, so you'll be sure that the device will receive it, even if it was sent while the device was offline.
There is no difference between configuration and commands about the content.
It is true that you can only send 1 config/device/second, but it most cases this is enough.

QUESTION
I currently have a bunch or things registered in the AWS IOT console. i am building a web-page that will list things and display attributes from each things shadow. i am struggling to understand how do i know if a thing is currently online in (near) real time. I am retrieving the things using the PHP SDK
...ANSWER
Answered 2020-Feb-03 at 19:19Use Fleet Indexing to track status of connectivity.
The information indexed per Thing:
{name:connectivity.timestamp, type:Number},
{name:connectivity.version, type:Number},
{name:connectivity.connected, type:Boolean}
*Remember the clientId used to connect must also exist as a Thing in the Thing registry.
