Collect data from RPI3 to Emoncms

Hardware
21

In your sketch, you have:

  Serial.print("6");
  Serial.print(" ");
 ...
  Serial.print(power1);         // Apparent power 
  Serial.print(" ");
...
  Serial.print(power2);         // Apparent power
  Serial.print(" ");
...
  Serial.print(power3);         // Apparent power
  Serial.print(" ");
...
  Serial.print(power4);         // Apparent power
  Serial.print(" ");

  Serial.println();

That will print, for example

6 123.45 234.56 345.67 456.78 :leftwards_arrow_with_hook:

So that emonhub correctly interprets the data, you must have exactly the same number of data as you have in your sketch. You have 4 items of data. The NodeID is not data.

Therefore, you must have:

[[6]]
    nodename = Arduino1
    [[[rx]]]
       names = power1, power2, power3, power4
       datacode = 0
       scales = 1,1,1,1
       units =W,W,W,W

You must have “datacode = 0” because the numbers are readable by a person - they are not byte data that must be decoded.

@pb66 - Am I correct here?

@Robert.Wall ,

I’ve tested what you’ve said and i have the same issue in the emonhub config (cf my previous screen of the logs).

23

Mainly yes, except the “datacodes = 0” is the default of the serial interfacer and the scales (of 1) and units don’t have any effect so all that is needed is

[[6]]
    nodename = Arduino1
    [[[rx]]]
       names = power1, power2, power3, power4

Please stop posting pictures of logs or code if you can!

As I’ve asked and explained more than once, it is much better for you and us if you copy and paste code and logs etc.

If you read what your logs say, both attempts to create interfacers (one for each Arduino) fails with the same error message

so the best pace to look for the issue is the [[[runtimesettings]]] in emonhuub.conf, if you are unsure, post the conf here for us to see (text please not a picture!).

I have also explained a couple of times, that you do not need the rfm2pi interfacer if you are not using an rfm2pi or emonpi, so you can delete that interfacer from emonhub.conf completely or a easy tip, just add a “#” (hash symbol) to the beginning of the “Type=EmonHubJeeInterfacer” line to disable it without deleting the config eg

[interfacers]
### This interfacer manages the RFM12Pi/RFM69Pi/emonPi module
[[RFM2Pi]]
    #Type = EmonHubJeeInterfacer
    [[[init_settings]]]
        com_port = /dev/ttyAMA0
        com_baud = 38400                      # 9600 for old RFM12Pi modules
    [[[runtimesettings]]]
        pubchannels = ToEmonCMS,
        subchannels = ToRFM12,

        group = 210
        frequency = 433
        baseid = 5                              # emonPi / emonBase nodeID
        quiet = true                            # Report incomplete RF packets (no implemented on emonPi)
        calibration = 230V                      # (UK/EU: 230V, US: 110V)
        # interval =  0                         # Interval to transmit time to emonGLCD (seconds)

disabling this interfacer will tidy up your emonhub.log and make it easier to read.

Hi,

I’m really sorry for the pictures , this is the runtimesettings in emonhub.conf:

[[[runtimesettings]]]
        pubchannels = ToRFM12,
        subchannels = ToEmonCMS,

        # emonhub/rx/10/values format
        # Use with emoncms Nodes module
        node_format_enable = 1
        node_format_basetopic = emonhub/

        # emon/emontx/power1 format - use with Emoncms MQTT input
        # http://github.com/emoncms/emoncms/blob/master/docs/RaspberryPi/MQTT.md
        nodevar_format_enable = 1
        nodevar_format_basetopic = emon/

I’ve disabled the EmonHubJeeInterfacer like you’ve recommended and it’s more clear like you said , i’ve now this:

Thanks for your help and sorry again for the pictures ^^‘’

There should be more than one runtimesettings in emonhub.conf, each interfacer has it’s own runtimesettings section. I’m guessing what you’ve posted has nothing to do with either of the Arduino serial interfacers as you have previously confirmed the following

. . . and now I see where the issue is! That should be runtimesettings not runtinesettings, a typo from one of my previous examples (now fixed!).

Thanks for all your help , it seems like i’m receiving data perfectly now :smiley: , i just need to check if this is the data that i want.

Thanks again
