Has anyone figured out how to integrate this into weewx yet?
have you tried the interceptor driver?
https://github.com/matthewwall/weewx-interceptor
this driver works with a few different types of bridge hardware, including the acurite bridge (old or new firmware), lacrosse gw1000u, oregon scientific lw301/lw302, and fine offset 1000 (aka, observer).
over the past few years there have been many different approaches to getting data from bridge hardware, so the interceptor is an attempt to consolidate the best practices for each before we make an explicit driver for each type of hardware.
btw, when you use tcpflow, do you pipe the output to process it or dump it to file then read the file?
