Im trying to program a emontx v3.2.
My problem is when i use sketch for rfm/3.2 3phase voltage i dont get the data in emoncms. i can see that i get a warning in emonhub log.
if i try other sketch for 3.4 i get compile error.
I tested platformio but i did get this to work. i use arduino ide to program.
I am sorry you have a problem, but the first rule is you must give us enough information to be able to help you.
OK, so you have a problem, but how does that help us to know what your problem is?
(Take a look at the first few points on the FAQ page when you have a moment to spare.)
What IS the warning?
My first guess - and given what you have written, it is only a guess: Have you got the correct data format defined in emonhub.conf?
I do not, cannot, nor will not support platformio. I too use only the official Arduino IDE.
Did you set up your Arduino IDE according to the page in the ‘Learn’ section - including all the libraries you require?
Is this the sketch you are using:
/*
emonTx V3 CT1234 + 3-phase Voltage example
An example sketch for the emontx module for
3-phase electricity monitoring, with 4 current transformers
Authors: Glyn Hudson, Trystan Lea
Builds upon JeeLabs RF12 library and Arduino
Extended for 3-phase operation: Robert Wall
V.1 7/11/2013 Derived from emonTx_CT123_3Phase_Voltage.ino
V.2 28/1/2015 Altered to use low-pass filter and subtract the offset, to remove filter settling time.

V1.3.1 - Remove filter settle routine as latest emonLib 19/01/15 does not require
V1.3 - fix filter settle time to eliminate large inital reading
V1.2 - fix bug which caused Vrms to be returned as zero if CT1 was not connected
V1.1 - fix bug in startup Vrms calculation, startup Vrms startup calculation is now more accuratre

#define emonTxV3 // Tell emonLib this is the emonTx V3 - don't read Vcc assume Vcc = 3.3V as is always the case on emonTx V3 eliminates bandgap error and need for calibration http://harizanov.com/2013/09/thoughts-on-avr-adc-accuracy/

my problem is that i dont get the input in emonpi.
My guess was correct. These two lines do in fact tell you all - when you know the secrets.
NEW FRAME : 10 tells me that your V3.2 is NodeID=10 data length: 24 is not valid for ... tells me that the entry in emonhub.conf does not match the data that your sketch is sending.
Now - the first problem, you have a sketch that will not give you the correct values for a 3-phase system. The sketch you have is only for a single phase UK mains supply.
Note line 26. You must have the RFµ library for your V3.2
All the instructions to set up and calibrate the sketch are in the comments at the beginning.
When you get that working, you need to edit the entry in emonhub.conf. You can do this in your web browser from emonCMS.
Go down to the block that looks like this:
Not for the V3.2, but it should be possible to add it to that 3-phase sketch. You will need to take the temperature measurement parts out of the sketch you originally used and merge them into the 3-phase sketch.
im trying to get this sketch with temp. ds1820 one wire.
anyone that can guide or show me where to input code for one wire. i tryed but compile failed and it seems like im not understand it 100%.
Thinking further about your problem, it might be easier for you to use the modern 3-phase PLL sketch. Although this does incorporate temperature measurement, only one temperature sensor may be used, and it will not work with the RFM12B radio that your emonTx V3.2 uses.
The code that drives the RFM69CW is a separate file, and I have an equivalent file for the RFM12B radio. I have not tested it with the 3-phase sketch, I might be able to do that for you in the next few days. If you think the sketch will be useful to you, I will do that, but you must wait for a few days until I have the time to do it. Please let me know if you would like me to do that.
If you want to use the ESP8266, then the radio is disabled automatically when the option for the ESP8266 is selected, so you can use that sketch without modification.
There is also an option to set the I/O pin assignments for the emonTx V3.2. Be sure to download and read the PDF file that explains all the settings.
