Hi Guys,
Forgive me if there is a thread on this but i couldn't see one. I am not entirely sure what this would come under so let me know if i am in the wrong place.
I have a pi with the rfm12pi installed and I am using the gateway SD card image to forward data to my own Linux server.
Is there an easy solution to remove the Pi from the equation and just plug a rfm12 type usb receiver into the linux box that is running the emoncms and have it all work that way? As i have read about using multiple PIs as gateways to the same emoncms server i assume I should be able to have a usb dongle in the linux server and then put a Pi somewhere else on the network to relay data from sensors that are too far to reach the linux server and dongle?
I am aware of the need to maybe control this with different group number etc so both receivers can't see the same sensor.
Is there a guide and a device that is recommended? I see there are a few options for hardware.
Thanks
Ja
Re: USB RFM12
Yes you can do this, but you'd obviously need to modify the sketch to point at the USB serial port.
take a look at http://www.digitalsmarties.net/products/jeelink
If you google "jeelink emoncms" you should find some pages to help you

Ukmoose,
Thanks for the heads up. Sorry the system still fails to mail me when someone comments on my thread.
I have ordered a USB dongle for the server and will start playing with that this weekend.
Thanks again

Re: USB RFM12
Help please.
I am trying to use a JeeLink USB dongle to get data from an emonTX V3 to emoncms. I have the emoncms up and running pluged in the JeeLink, followed the instructions here: http://emoncms.org/site/docs/installwindows - installed Python, pyserial and the pylink script. The pylink script stops on the readline.
I am guessing I need to program the JeeLink and it does work straight out the box. If I do can someone point me in the right direction as to how to program the JeeLink and where to find some suitable code.
Many thanks,
Geoff
