I´m totally new on ThingSpeak and I would like to test GoogleGauge functionality. Pluggin I imported and is showed on the screen. Now, very stupid question, since I was not able to find info regarding:
how do I modify, with PUT or any other message the value of the gauge, from my browser or my embbeded system?
Thanks in advance,
The simplest way is using the syntax from Data import/export tab.
Enter the following into your browsers address line:
You can update multiple fields by adding: &field2=[value]&field3=[value] etc. Note that you need to enable these channels beforehand from Channel settings.
From your embedded system you need to learn how to send a similar http message.
