The emonhub.log shows us there is no communication with the RFM2Pi board (at 9600)

Am I right to assume you are now using the latest emonSD image? can you confirm?
If you are have you changed anything else related to the serial port other than the “com_baud=” in emonhub.conf?
Can you confirm what model of Pi B you are using? Is it a B(256mb ram), B(512mb ram) or B+ ? (I am not sure the emonSD will even run on an original 256mb Pi B).
If using a B or B+ (possibly even a 2B) and the com_baud is set correctly but still no joy it maybe a serial port mapping issue see “EmonBase with RPi B1+ - no serial data”
Can you also post the result of running this from the command line ?
ls -la /dev/{tty{AMA,S,USB},serial}*
[edit] Can you also confirm YOU HAVE NOT used the “update emonBase” (or “update RFM69Pi” depending on time of last update) button on the admin page of emonCMS?
If you haven’t please avoid doing so. Since your device is RFM12 using the update will stop it in it’s tracks as it will install RFM69 firmware which will not progress beyond initialization from boot. If you have then the firmware will need reverting to a RFM12 version.
