How to specify different datastream in

Submitted by EnergyRnR on Tue, 22/11/2011 - 23:32

Hi,

can someone point me to a way of specifying multiple datastreams when sending feeds to pachube. E.g. using https://github.com/openenergymonitor/NanodeRF/blob/master/nanodeRF_ctonly_pachube/nanodeRF_ctonly_pachube.pde as an example, it works for me, but I'm not sure how I direct emontx voltage for example to one datastream or feed ID, and the power measurement to another ID etc.

thanks a lot for any pointers.

I'm not as good with strings as most of the guys here, but from what I see, the Pachube 'send' string only has only one datastream at the moment called 'power', so you need to add other datastreams to the string, something like;

str.reset();

str.print("power,");

str.println(emontx.ct1);

str.print("voltage,"); // voltage is the feed ID

str.println(volts); // volts could be your variable which holds the current voltage

str.print("temp,"); //temp is the feed ID

str.println(temp); // temp could be your variable which holds the current temperature

Note that str.print has been replaced by str.println in places, to indicate to Pachube that they are seperate datastream.

Fortunately, Pachube has a new debug screen, so if you have any problems with it not working - check the debug screen first!

I'm not using this sketch, but my multiple Datastream feed is at https://pachube.com/feeds/34843 and my feeds are called sd1, sd2, sd3 and so on.

Please let me know if it works!
