weewx skin that produces data for FHEM Installation instructions: 1) run the installer: wee_extension --install weewx-fhem.tgz 2) restart weewx: sudo /etc/init.d/weewx stop sudo /etc/init.d/weewx start Additional instructions: The output file "fhem.txt" must go to the a folder where FHEM can see it, such as the public_html/fhem folder of a web server. Use an FTP or RSYNC report in weewx to transfer the file. For example, this fhem_xfer stanza in weewx.conf would upload the fhem.txt file using FTP: [StdReport] [[fhem]] skin = fhem HTML_ROOT = fhem [[fhem_xfer]] skin = Ftp HTML_ROOT = fhem user = username password = pw server = hostname path = /home/username/public_html/fhem The file fhem.cfg is a configuration file for FHEM's module HTTPMOD. There are two variations included in this package. fhem-klimalogg.cfg uses the klimalogg schema, fhem-wview.cfg uses the default weewx schema (wview). The fhem.cfg file contains the configuration examples for current values only; for min/max values, heatindex and dewpoint values use similar syntax for setting readingXXExpr /readingXXName / readingXXRegex.
