Is there a way to chart a digital variable on ThingSpeak - e.g. an ON/OFF indication for a heater status over time? Of course, one could configure +5V=ON, 0V = OFF, and display these two levels of analog voltage, but it would be good to have true digital display capability.

thanks 

Gerry

On the digital variable display. If you send 5V and 0V (5 and 0), and then use "&type=step" on the chart API and the presentation will be "digital".

Is this close?
