RFM12pi alternative? (Jeenode usb)

Submitted by Guest on Tue, 03/12/2013 - 18:04

Hi,

I'm looking for an alternative to the RFM12pi daughter board to communicate with EmonTX|H sensors. This is because the GPIO ports on my Raspberry are already used by a Razberry daughter card (http://razberry.z-wave.me).

What are the solutions? From my understanding it's possible to plug something like the Jeenode USB (http://jeelabs.com/products/jeenode-usb) on my Pi USB port and communicate with sensors, am I right?

Thanks in advance.

A jeelink USB available from JeeLabs works well. It will work exactly the same as the rm12pi when loaded with the rfm12pi code. It will be fully compatible with the oem gateway, just change the port to be tty USB. A jeenode USB will also work in exactly the same way.

Is there any instructions on how to change the serial port of rfm12piphp? And can the baud be changed too? the current code of the jeelink runs at a baud of 57600.

I have just purchased a jeelink and have it hooked up to my ubuntu server. Just as a side note, ESXI passes through the USB serial port of the jeelink easily.

Thanks for your help and fantastic project.

Just a small note to say emonHub can support multiple "Jee" type devices including RFM2Pi and JeeNodes. The Port and Baud for each instance can be set in the configuration file.

emonHub can be used as an alternative to the raspberrypi module for emoncms.

Hello Mike,

I've used the same configuration, ubuntu server using the USB through ESXI. I'm able to read data using minicom, but if I log to the emoncms it says that the interface script is not running. Have you done any other changes to the .php to make it work?

Many thanks
