Did you also do the change to the inittab and reboot afterwards?

/me feels stupid...

Thanks, now it works.

I edited the wiki to make the inittab step more visible.

I am having a similar problem. I have a new raspberry pi, with the raspberrypi rfm12b module v1. I have done the cmdline and the inittab swtich. My rfm module has the green light on solidly. 

When I try to use minicom, I get:

Welcome to minicom 2.6.1

OPTIONS: I18n
Compiled on Apr 28 2012, 19:24:31.
Port /dev/ttyAMA0

Press CTRL-A Z for help on special keys

But it says offline at the bottom and there is no command promt. Is my rfm12b module not talking to my RPI? What does the solid green light indicate? Any suggestions?

Marquis27, Do you see anything in the log file? 

Try:

sudo service rfm12piphp restart log

and then

tail -F -n 40  /var/log/rfm12piphp.log

As documented here:

Sorry, I haven't installed the emoncms on the RPI yet. I was actually planning to just modify the python script to send the data to my remote emonCMS installation without doing the whole RPI install. 

My understanding is that the rfm12b v1 would be able to output to the serial without doing all the install. Is that incorrect? I have basically a clean RPI install, with the two UART modifications done, with a rfm12b module on it. I thought that would be enough to talk to emontx.

Is there any other way I can test the module without installing everything? Thanks.

Currently, the gateway is designed to be configured through emoncms as a GUI. It has been pointed out already that the whole emoncms local install just for the sake of configuring the gateway with three parameters is a bit overkill, and I'm working on a new implementation with configuration through a config file.

It is still work in progress, not stabilized, and all, but if you want to catch a glimpse, here it is:

Anyway, if your module is receiving anything, you should at least see something in minicom.

Hi Jerome.. The Python gateway you wrote looks to be ideal. I am still reading thought it trying to understand it all. Do you have an example on reading say a tx or a temp. I take it I basically need to create a subclass for node? 

Thanks for sharing this. 

Hi.

I need to add examples / documentation...

Not sure what you mean by "read a tx" but if you mean listening to an emonTX through the RFM2Pi card, then it should be easy, just adapt the example config file to your configuration. You can remove the socket listener, it is then useless.

"reading a temp". If you mean reading a temp from a sensor on the Pi itself, then you need to either create a specific subclass, or create a small program (any language, but I could provide a 4 line python example) that reads the sensor, then sends data to the gateaway via a socket. In this case, in the gateway config, keep the socket listener, and of course, make sure the port number is the same in the gateway and the sensor reader.

Please ask for more help if any thing is unclear. I just got back from holidays, and I may be more responsive.
