ESP8266 Community Forum

I'm new to the ESP8266 and have a question for the experts. Is it possible, and if so are there examples, of an ESP8266 sending data collected from a sensor directly to AWS? Specifically, I am interested in replicating an arduino+Raspberry pi+python solution I have already but want to dramatically simplify my hardware if possible.

I'm looking for advice or examples on how I could push data collected from a sensor to DynamoDB using either the http request method or some other (hopefully simpler) method.

Thanks,
John

From the link you gave about the Amazon service it sounds like it just needs a regular http post, so it should work fine from an ESP8266 and there are plenty of examples about of how to do it, eg here.

Thanks for the pointer on how to fire off the request. I got it working and have also leveraged the NTP work by another user to get a current timestamp (required for the post to AWS).

The issue I am facing now is that AWS requires I construct a hashed signature using HMAC-1 which I can't find any good way o accomplish.

Starting to look like I need to wait for an ESP8266 version of the AWS arduino SDK. Seems that the sdk they've built for arduino spark core doesnt work with arduino/esp8266.

After several attempts at trying to figure out how to make the core arduino libraries by Amazon work for the ESP, I think I have concluded this is beyond my current skill level. If anyone has successfully integrated the Amazon AWS library into an ESP project, I would be very grateful for some insight on how this was done.

Surely I am not the only one who sees potential in these devices posting data directly to the AWS infrastructure with all the component services they have to play with (and a free usage tier to keep costs low).
