i am using the emontx shield for my measurement and considering about transmitting the measured data wirelessly to the computer. but i donnot know which one is better for beginners to start working on. in the introduction of nanode RF that says we have to assemble the parts by ourselves however in the shop there are some pre-assembled one. so which one is correct? i am in australia, so i think the 433Mhz one would match my emontx shield?

Re: nanode RF
You know which version of the emonTx shield that you bought, you must use the same radio frequency for your nanodeRF. The through-hole nanodeRF is very tricky to assemble so I suggest you buy the ready assembled SMT version with the same RF module that your shield has.
Re: nanode RF
"433/868Mhz RFM12B (HopeRF) wireless transceiver to transmit/receive data to other OpenEnergyMonitor and JeeNode modules" is the specification of my emonTX shield, so i might get the following:
http://shop.openenergymonitor.com/nanoderf-smt-433mhz-pre-assembled/
cuz the frequencies are matched.
another question about the product from this link, is it a shield that i can put on my arduino board or it is just independent device?
Re: nanode RF
The nanodeRF is stand-alone, but of course it needs a power supply and an Ethernet connection to your router and onwards to the server - either your own or emoncms.org
But if you are planning to have your own server in the future, you might want to buy a Raspberry Pi and the RFM12Pi expansion board instead. The Pi will function as a server and run your own local emoncms.
Re: nanode RF
nanodeFR is able to receive the data from the emonTx shield as well? guide codes are all about the emonTx, not mention emonTx shield at all.
Re: nanode RF
Yes.
Compatible with OpenEnergyMonitor modules (emonGLCD, emonBase - NanodeRF etc.)
Re: nanode RF
So would that mean I can plugin the Emon Shield into the NanodeRF and use it with the right sketch? Or is that not pin compatible?
Re: nanode RF
No you do not plug the shield into the nanodeRF, that is what the radio link is for.
You plug the shield into an Arduino. It transmits the data (current, voltage, power etc) to the nanodeRF by radio. The nanodeRF receives the radio signal and sends the data out over the Ethernet connection.
