I'm trying to experiment ThingSpeak in order to plug several "things" to send data. The problem I can see by now is it doesn't seem to be possible to actually specify the "created_at" field in GET/POST requests sent to record value. I can't expect my things to alway be online and send their data as the events occur.
So is there a way to force value's timestamp while sending data ?
Try to specify your date format like in this example:
As far as I know its not possible to assign different timestamps to fields in the same update- the created_at value is assumed to apply to all values you send in a single update.
You could, if you really wanted to, set a timestamp value as another field (thingspeak fields dont have to be only numbers) but you would have to devise your own processing and graphing routines.
