Irregular tx data receipt

Is there a guide for doing this with multiple emonTX units being connected via serial to a single Pi?

Not a formal one but a few here.

With 3, I’d be inclined to get a TTL to USB converter and plug them into the USB port of the Pi.

Emonpi - multiple serial-usb

Can i get 2 (or more) inputs via a serial-usb connected to the emonPi? Now i have one connected via the [RFM2Pi] in [intercaces] by changing the comport and baudrate. I would like to connect 2nd arduino via serial.

Hi Paul Thanks for the cable suggestion. Thought I would document here (for when I inevitably break something and want to refer back…) what I did to “wire” my two emonTx’s to the emonPi: Get two of the cables you linked above, 2x male-female USB extenders, and connect straight to the UART ports of the emonTx’s and USB ports of the emonPi Check they show up: pi@emonpi:~ $ lsusb Bus 001 Device 005: ID 0403:6001 Future Technology Devices International, Ltd FT232 Serial (UART) IC Bus 001 D…
