Emonbase Problems

I am having problems with my Emonbase / Emontx Shield system. The system hardware is as follows

EmonBase - Raspberry Pi based web-connected base-station

(RaspberryPi RF add-on: RFM69Pi - 433Mhz,

Raspberry Pi: Raspberry Pi 2, Pre-build SD Card: Pre-Loaded microSD Card,

Enclosure: Raspberry Pi Case - Black,

Network Adapter: USB WIFI Edimax EW-7811UN)

EmonTx Arduino Shield SMT running Shield_CT1234_Voltage sketch on Arduino Uno
(Frequency: 433Mhz (Worldwide), Arduino Shield Headers: Standard Headers)

The Emonhub software starts up ok and logs the data from the Emontx Shield ok for a minute or so then fails. The Emonhub log following seems to show errors from the RFM69pi then says the RFM2Pi thread is dead.

Does anyone else have these problems?

Re: Emonbase Problems

Good work getting uip and running.  

What sketch are you running on your emonTx shield? It looks like a decoder error. The default emonhub.conf is expecting 5 x integers "power1, power2, power3, power4, Vrms". You might have to adjust the .conf file (edit via emonHub tab in local Emoncms to match what your transmitting. 

 

[[6]]
    nodename = emonTxShield
    firmware =emonTxShield
    hardware = emonTxShield
    [[[rx]]]
       names = power1, power2, power3, power4, Vrms
       datacode = h
       scales = 1,1,1,1,0.01
       units =W,W,W,W,V

Re: Emonbase Problems

Hi,

I'm running the Shield_CT1234_Voltage sketch on Arduino Uno. I edited the .conf file to match the example but it didn't fix the problem,

I logged into the emonpi using putty and found the following exception when the thread died. Any ideas?

 

[email protected] ~ $ Exception in thread RFM2Pi:

Re: Emonbase Problems

It looks like you are getting some rogue characters slipping in from somewhere. The payloads should only consist of numeric values beyond a leading "?" or "OK" and the trailing rssi in parenthesis. The traceback confirms the "-\xb33" is not an integer and causes the the thread to crash as the rssi should be an integer and not contain "�". emonhub could be altered to handle the exception better but the fact remains the serial data is being corrupted somehow. 

It looks like it only effects the invalid packets (but this is quite a small amount of log so may not be the case) ifthat is the case the issue may be sidestepped by setting [[RFM2Pi]] [[[runtimesettings]]] quietmode = true in emonhub.conf, that will instuct the rfm69pi to not pass the invalid packets, again not really a fix.

To fix this you will first need to know if its coming in via the serial port, try stopping emonhub " sudo service emonhub stop" and using a serial console like "minicom" to see the raw serial data, from what you've said it shouldn't take long to see whether there are any non-numerical values being passed outside the range of 0 to 255, or odd symbols etc

the rfm69pi to emonhub connection must have exclusive use of the serial port and if anything else attempts to use the port then you will get un predictable results. I sort of half expect an outside influence as there is no reason for the rfm69pi to pass erratic data and yet emonhub logs the corrupt data almost immediately upon receipt.

So can you test does it do it in quiet mode? Can you see anything in minicom? (you can restart emonhub again with " sudo service emonhub start" after testing) and also do you know what version firmware is running on the rfm69pi? or more importantly what baud it is running at?

Re: Emonbase Problems

Hi Paul,

Thanks for your assistance, I set the quiet mode to true as follows, It looks like the bit rate is 38400. not sure how to see the firmware version.

    Type = EmonHubJeeInterfacer

        pubchannels = ToEmonCMS,
        subchannels = ToRFM12,
       
        # datacode = B #(default:h)

        group = 210 #(default:210)

I also had a look at the minicom output with the emonhub stopped and this is data from minicom

Could this be 433 MHz interference?

Re: Emonbase Problems

I'm not able to say with absolute certainty that it's not RF interference, but I suspect not. I would expect anything not discarded or handled by the rfm69pi firmware to be numerical, anything else that is not a valid command and actioned will be garbage and cause the packet to be discarded.

If you send a question mark from minicom, the help text should be returned which will include the firmware version. Is this help text totally legible or contain rogue characters like the log above?

Another test could be to remove the rfm69pi and retest with minicom, there should be no data traffic with emonhub stopped and the rfm69pi removed as they need exclusive use. If there is any data appearing in minicom that would suggest something else is using the serial port and if that data is garbage as above, it may be using a different baud rate, so you could try some other baud rates to help identify the source by making the data legible.

If there is no other serial traffic, it may be well worth trying to (re)install firmware to the rfm69pi.

Another quick test from emonhub could be to set 868MHz in emonhub.conf since your rfm69pi is tuned for 433 it will almost certainly not receive anything unless it is really close and ~868Mhz. That should help determine if it's from the serial port or air-bourne noise perhaps.

Re: Emonbase Problems

The help text is corrupted as well.I removed the rfm69pi and there was no data.

I tried setting to 868 mhz and I was still getting corrupt data. Went back to 433mhz and turned off the emontxshield and the corrupt data was still there.

I'm not sure how to reinstall the firmware.

Re: Emonbase Problems

Do you recall the firmware version from when the help text printed?

The rfm69pi wiki has a guide on how to install firmware, I think most of the software is in place on the sdcard image you have although the "reset" interval duration will need to be edited if you are using avrdude v6.1, I'm sorry I don't recall if it is 5.11 or 6.1 on that image.

You should be able to update the reset script by just doing a git pull from the avrdude-rpi folder or you could just edit the /usr/bin/autoreset file directly,

The hex file to upload would probably be https://github.com/openenergymonitor/RFM2Pi/blob/master/firmware/RFM69CW_RF_Demo_ATmega328/V13_RFM69CW_RF12_Demo_ATmega328.cpp.hex

There is also update routines on the "emompi" image and also one in the rfm69pi repo I'm not sure the included one does the rfm69pi or not and the repo one uploads an earlier compile of the firmware (but could be easily edited)

Sorry the instructions are a bit crazy but I'm not 100% sure what bits you have exactly but I am 100% sure bits will have changed since and the wiki guide includes installing stuff you have already.

Re: Emonbase Problems

Was emonhub stopped for the attempted firmware upload?

If there was no communication the error output would be quite different, it seems avrdude is able to speak to the rfm69pi's AVR but the responces arn't as expected, that maybe coincidence but it very much looks like something is still upsetting or interfering with the serial port.

Can you confirm you have no other hardware, wires or devices attached to the Pi's gpio and that you are using a "stock" shop bought SDcard and have not altered anything?

Can you get an ethernet cable to the Pi so the wifi dongle can be removed?

Did you purchase the power supply from the OEM shop? or do you know for sure it is stable/big enough?

Unfortunately yes, the system is a bit of a handful when things aren't going as intended.

Re: Emonbase Problems

I think you need to stop emon hub before updating since it's using serial port:

sudo service emonhub stop 

Updating RFM69Pi firmware should not be required. Firmware has not changed for a long time. It's very strange you getting corrupted serial data, could be hardware issue. Does the unit visible look OK and properly seated ont he the Pi?  If you are still having issue drop an email to [email protected] and we'll sort out a replacement.

Hi,
I did stop emonhub service before doing the upgrade. It all looks good mounted ok etc. I will send an email.
