RFXTRX install

Configuration
1

HI,

Sorry for what might be a very silly question, but how to I config the RFXTRX device which is plugged into a USB port?
The instructions say

Example configuration.yaml entry

rfxtrx:
device: PATH_TO_DEVICE
debug: True

and gives an example to the device of:
device (Required): The path to your device, e.g. /dev/serial/by-id/usb-RFXCOM_RFXtrx433_A1Y0NJGR-if00-port0

But where do I find the /dev/… etc.?

Thanks in advance
Dave

Good that you’ve figured it out. But it could be useful for others If you put the steps here too.

The instructions for figuring out which usb device is your rfxtrx are pretty much the same as for ZWave USB sticks. See here and look for the bit about finding the name of your USB device and locking it to a fixed name.

It’s usually /dev/ttyUSBx where x can vary across reboots. The longer name is a symlink to that, but should be more consistent. I’ve locked mine to /dev/rfxtrx using the instructions linked in the ZWave notes.

Also here is another clear explanation of how to find the usb path and how to lock it: https://www.domoticz.com/wiki/PersistentUSBDevices
