EmonBase doesn't receive input from emonTXShield with RFM69CW

Getting Started
1

Hello,
I have a problem in receive information from my emonTXShield. I don’t see any input on input setup menu in Emoncms.
This in the text in the setup input menu of Emoncms:

No inputs created

Inputs are the main entry point for your monitoring device. Configure your device to post values here, you may want to follow the Input API helper as a guide for generating your request.

I Have Arduino UNO with emonTxShield and RFM69CW. I use the sketch Shield_CT1234.ino.
This is the serial monitor with che configuration of nanode RF

#define RF_freq RF12_433MHZ
NodeID=6;
neworkGroup=210
#define RF69_COMPAT 1

The LED digit on emonTX Shield pulse regolarly so the trasmission will be regular my be.

This is the EmonHub config in Emoncms

[[6]]
    nodename = emontxshield
    [[[rx]]]
       names = power1, power2, power3, power4, vrms
       datacode = h
       scales = 1,1,1,1,0.01
       units =W,W,W,W,V

I’ll wait for your help!

Thank you very much!

Is this an emonPi? Or are you using a RFM2Pi board? If it’s the latter, can you see the LED on it flash roughly in-sync with the emonShield’s LED?

Are you using the emonSD image? If you are using an RFM2Pi board you will need to alter the com_baud setting in the [[RFM2Pi]] settings in emonhub.conf, probably to 38400 if recently purchased.

Can you download and post the emonhub.log?

I’m using a RFM69Pi - 433Mhz board with the emonSD image pre-build purchased together the Emonbase.
Unfortunately in this moment I can’t verify the settings of com_baud in emonhub.conf but I’ll verify it as soon as possible.
Thank you for the suggestion.

This is emonhub.log.

I can’t see any flash of LED on the RFM2Pi.
What about com_baud, in my case is set to 38400.

Thank you for the information you will give me.

Hi,
I saw that there is a warning about device communication error in emonhub.log, it could be the problem concern no input?
What about that warning? There is a problem with RFM2Pi?
Thank you.

Thank’s for your suggest.

That’s the correct baud rate. All looks correct from the logs.

Is the LED on the emonTx flashing once every 5s.

Does the LED on the RFM69Pi light up for a few seconds when power is first connected to the emonBase?

Update: I see you have ordered an emonBase and emonTx shield, have you verified you have attached the RF module correctly. Please could you send an image showing the top and bottom of the assembled emonTx shield.

What sketch firmware are you running on the emonTx shield?

8

The very first line of the log says there is a comms problem with the serial port but the preceeding (missing) lines would have told us what port address and baud were being used.

What model of Pi are you using?

Can you confirm the rfm2pi board is connected correctly to the top ten pins and that the underside of the rfm2pi’s antenna is not touching the unused gpio pins.

Tantk’s for the suggestion, I try to disconnect and re-connect the rfm2pi and now is ok. I can receive the input without problems.
Thank you.
