Emonupload not finding USB serial

Hi all
I’ve just bought a new emon TX and am trying to update the sketch to monitor 3phase.
Setup emonupload without errors but when I run it I am getting the following:

Serial upload latest/openenergymonitor-emontx-3phase.hex:i

ERROR: USB serial programmer NOT found

Error: Cannot connect to RFM69Pi receiver. Upload only…NO RF TEST

I am using the USB/UART interface bought from the store so guess it’s not that and I can see the USB when I plug it in, ie I get a ttyUSB0 and can connect to it, I get the following in minicom:

emonTx V3.4 Discrete Sampling V3.10

No EEPROM config
RFM69CW Node: 8 Freq: 433Mhz Group: 210

POST…wait 10s
‘+++’ then [Enter] for RF config mode
(Arduino IDE Serial Monitor: make sure ‘Both NL & CR’ is selected)
CT 1 Cal 90.90
CT 2 Cal 90.90
CT 3 Cal 90.90
CT 4 Cal 16.67
RMS Voltage on AC-AC is: ~250V

So that seems to be working…

So not sure what I am doing wrong in emonupload. Any pointers greatly appreciated!


OK, it’s late and I’m tired.

very sorry but this turned out to be a simple permissions on the tty port :frowning:

It now runs and seems to have uploaded the sketch as my emonbase is now showing a new set of inputs under “node3phase”

Sorry for the bother, great little program that!

Thanks all
