The openenergymonitor project is really a great think! But I want to expand this... When you see online that there is a device uses a lot of energy, or you are forgotten to switch of the dishwasher (or something else) you can switch of through the internet. Is it possible to send data to the nanode RF (via the internet) and so communicate with the emonTX to turn off a relay ?

Re: project expansion
It sure is, but you should rather power the emonTX from the USB and not via a battery. emonTX supports jeeports, therefore is compatible with the relay plug: http://jeelabs.com/products/relay-plug
Alternatively you can use the RFM12B to send OOK (yes, OOK!) to RF controlled power sockets and that's an easier alternative. There is code already available for the KaKu (http://www.klikaanklikuit.nl/home/) seem to be particularly popular, but I managed to port the code for a Chinese unbranded model quite easily.
Re: project expansion
What kind of a "Chinese unbranded model"? Is there any link to it?
Re: project expansion
I bought it from a local store, it has EWM200R written on the back. Googling takes me to this page, my unit is identical, other than it is pure EU plug, without the male ground plug:

Re: project expansion
Can you post some of the code of how to control these "Chinese unbranded models" ???
Re: project expansion
I plan to document this and will post a link

Re: project expansion
I have a similar problem but loading the various sketches of nanode rf do not get results.
anyone has a working code on which to experiment.
Thanks
Re: project expansion
skymazda, can you expand on what the problem you have is?
Are you trying to control rf power sockets or something else?
If you are trying to send commands to rf sockets what hardware do you have?
At the moment there are too many variables to be able to help you.
