A little more testing tonight…
I connected to the emonTx, disabled the radio (x0), saved to eeprom (s), exit (x) and the emonTx continued to run.
I disconnected my serial to USB converter, and connected my serial to RS485 converter and the Rx light on the converter flashed in sync with the emonTx’s activity led.
I copied and pasted Glyn’s code from above and uncommented the line for Rs485, and commented the ttyUSb0 line (I thought that was for direct serial and not RS485.
### This interfacer manages the EmonTx3 ESP format serial [[SerialTx3e]] Type = EmonHubTx3eInterfacer [[[init_settings]]] # Un-comment line below if using RS485 adapter com_port = /dev/ttyRS485-0 # default com port if using USB to UART adapter #com_port= /dev/ttyUSB0 #com_baud = 115200 [[[runtimesettings]]] pubchannels = ToEmonCMS,
Log shows that it cannot open port and no data, so something is different between what Glyn posted and how the EmonPi is now…OUI!
