emontx and emonglcd talking

 hi
   
I built a emonglcd and a emontx and wanted to know if to make them talk was just program them with the same sketch

 

thanks

Re: emontx and emonglcd talking

No, you need to use the emonTx demonstration sketch in the emonTx, and the emonGLCD sketch in the emonGLCD. Both may be downloaded from Github - link at the top of this page.

In both sketches, you need to set the radio frequency to the frequency of the RFM12B modules, both of which must of course  be for and work on the same frequency.

(If you think about it, the emonTx has inputs to connect a voltage transducer, 3 current transducers, temperature and pulse inputs; the emonGLCD has pushbuttons and a temperature sensor for input and a graphical display output. Although the processor is the same, what is connected to it is vastly different in each.)

 hi
   
to make a correct test may i to program the emontx with the sketch "emontx_ct123_voltage.ino" and emonglcd with "homeEnergyMonitor.ino" ? is it functional?

 

thanks

Re: emontx and emonglcd talking

Yes, those two will work together. Remember if your RFM12B radio modules are 433 MHZ, this

#define freq RF12_433MHZ

is correct. If they are 868 MHz or 915 MHz, you must change this in both sketches.

hi
  
I tried to do a test with the software that I mentioned but my monitor appear strange data! the frequency is set in both 433 mhz

hi

I discovered that a resistance did not correspond as described in the kit! I have bought a correct! can I use the sketch of (emontx  -guide) "a_singleCT.ino" to check the current flow in a wire?

thanks

Re: emontx and emonglcd talking

That sketch was written to show the most simple example of how to measure current.

You can use that sketch to measure the current in a wire, but it does not have any program commands to send the measurement to your emonGLCD.

Re: emontx and emonglcd talking

  hi

I thought it was an example to measure and to send the measure to the emonGLCD or how to display the measured current?
There is a sample sketch to show how can emonTX send data to EmonGLCD?

thanks
