Please check top left of your emoncms webpage, there should be a 'Raspberry  Pi' link, select that, and look if you have a green box with the text 'RFM12 to Pi interface script is up and running' at the top of the screen?

Also, on the same page, check that your RFM12B is set up correctly, ie have you used a 433Mhz or 868Mhz RFM12B, and check Network group setting - it should match whatever the group setting is in the emonTX - the default is 210, whilst the Node ID's must be different for the emonTX & RaspPI

Have you selected the right frequency setting in the emonTX sketch?

Thanks for the reply.

Yes, the web page has a green box and the frequency is 433Mhz,  group=210, node=15 on Pi. The EmonTx is same frequency, node= 10 and group =210; it is defined on the sketch as well.

Can you try;

$ sudo service rfm12piphp restart log

followed by;

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

Hope this is helpful

The settings look OK, this looks more like a hardware problem than software.
Have you got another emonTX module to help identify whether it's a transmitting or receiving problem?

A more knowledgeable contributor may be able to help further.

Paul 

Thanks, I will await some other contribution.
