i have registered a set of devices in my aws iot device cloud for use with Alexa. All devices provide a set of sensor values e.g. temperature. Now i'd like to create a small html or json overview of all devices and sensor values. But i can't finde a smart function which returns me an entire dump of all devices in my cloud.
My best idea is to use a lambda function and AWS.iot and AWS.iotData SDK. First to list all devices in my cloud which i can iterate and second to read shadow of every single device.
I would expect this solution is ok for a small amount of devices but results in performance issue and cost when iterate hundred and thousand devices.
Can I use another solution in AWS to create a small report of the shadow state of all devices?
Or is lambda and AWS.iot SDK really the best way to do this?
