Node not appearing in Emoncms

Submitted by Martyn on Mon, 16/02/2015 - 18:25

Hi guys,

I've just finished setting up my EmonTx V3 with a direct serial connection to my RPi. I'm using the ready made SD card image and things appear to received by the RPi, which I've confirmed via Minicom, although I don't seem to get a nodeID passed in the output, i'm not sure if this is an issue though.

I've checked the log for emonhub and data appears to be uploaded ok, however no nodes are detected by emoncms:

Here's a snip from the emonhub.log

And a snip from minicom:

Any thought's to why the emoncms is not picking up the stream? I've tried tinkering with the nodes section of the emonhub.conf but it doesn't appear to make any difference.

Thanks in advance,

Martyn

The sketch used for a direct serial connection is missing a node id the sketch will need editing to add one see Serial link RPI<->EMonTX using Emonhub and there are other some other threads that may also help as you should be using a EmonHubSerialInterfacer rather than the default EmonHubJeeInterfacer (if you're not already).

Hi Paul,

Thanks for the swift response, I'm using the full DS V1.4 RFM12B firmware that was shipped with the unit, not the serial only firmware as I'd read that the stock firmware should work with both RF and serial.

I had previously modified my emonhub.conf to use the following setting:

[[SerialDirect]]

Type = EmonHubSerialInterfacer

[[[init_settings]]]

com_port = /dev/ttyAMA0

com_baud = 9600

[[[runtimesettings]]]

So hopefully i'm on the right track.

*Edit* - I've loaded the serial only firmware and added Serial.print("10 "); to the section where the print to serial sections start and it's working now.

It's a shame that No RF sketch is so stripped bare. Has anyone converted any of the full fat sketches to serial only so data from the AC/AC adaptor etc can be monitored?

Thanks,

Martyn
