Thanks guys.
I’m NOT using a USB to UART adapter.
I connected 3 jumper leads from an emonTx (running the 3 Ph firmware v0.11) to an RPi – connected as the pic in Robert’s post above – using Rx as the sending pin on the emonTx (plus 5V & GND connected).
I DO NOT have an RFM69Pi add-on board fitted to the RPi.
Via the emoncms page – per Glyn’s suggestion, I added the directserial interfacer and restarted.
But there were no Inputs to emoncms shown on the emoncms page.
/var/log/emonhub/emonhub.log gave the following …
2017-04-15 11:05:59,817 INFO MainThread Creating EmonHubTx3eInterfacer ‘SerialTx3e’
2017-04-15 11:05:59,823 ERROR MainThread [Errno 2] could not open port /dev/ttyUSB0: [Errno 2] No such file or directory: ‘/dev/ttyUSB0’
2017-04-15 11:05:59,824 ERROR MainThread Unable to create ‘SerialTx3e’ interfacer: global name ‘EmonHubInterfacerInitError’ is not defined
Then I started experimenting …
By changing the Serial Interfacer to dev/ttyAMA0 …
The log then showed that a serial port was now open.
There were some Inputs - Nodes 514, 516, 518, 519, 520, 522, 523, 531 & 693 each including 5 keys plus rssi but all with no values (NaN).
And the RFM2Pi has a ‘thread is dead’ problem.
Here’s the log …

Do you guys have any further suggestions?
I’m clutching at straws …
Should I just delete the RFM2Pi interfacer from the emonhub config?
I’ve tried changing the firmware file emonTxV3_4_3Phase_Voltage.ino - changing line 165 from RFM69CW to SERIALOUT but it made no difference.
I noticed that lines 117 to 123 have a slightly different content for Node 11 to that in the emonhub config file – should I use this instead?
Any other suggestions?
Thanks
