At one point I used weewx with the acurite driver, but then the USB base that came with station went out (turns out it's super sensitive to RF and having it next to my HF rig blew it right out.) I tried to continue using weewx, but had trouble getting the output from rtl_433 into something it could consume. Found it to be easier to just setup a cron'ed script that grabs the latest updates from a sqlite database and push it to wunderground's API. I keep meaning to post the whole thing to github, but I need to clean it up a bit first (and strip out credentials, etc.) Also, +1 to the i2c recommendation. My baro pressure sensor uses i2c, and it was pretty easy to set up. It also happens to have a temp sensor in it so I can log indoor temps, too. 73s de k7nrd -- James Bertelson [email protected] :wq _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
