One can specify stable device names under /etc/udev/rules.d. Weewx has sample files here: https://github.com/weewx/weewx/tree/master/util/udev/rules.d
I am unaware of the weewx-multi option. If the devices are identical, you’ll need to differentiate them. I have not needed to do this, but here’s a thread on the subject: https://www.linuxquestions.org/questions/linux-general-1/udev-rules-to-differentiate-between-multiple-identical-devices-822879/ > On Sep 12, 2019, at 8:22 AM, Andrea Cecilia <[email protected]> wrote: > > Hi there, > I just have tried for few months the "weewx-multi" option with two Davis > stations (1 VUE, 1 VP2).
