I read the readme.txt at https://github.com/glennmckechnie/weewx-owfs. In fact several times. I'm sorry but it is not clear to me what I'm supposed to do. Although I'm currently running Simulator, whenever I enable the line in weewx.conf that says [Engine] data_services = user.owfs.OWFSService it crashes weewx, with several lines of errors (posted above in entireity) but the main ones seem to be: CRITICAL __main__: **** No one-wire library found CRITICAL __main__: **** ModuleNotFoundError: No module named 'ow' CRITICAL __main__: **** ModuleNotFoundError: No module named 'pyownet' all this even though I have installed (several times now) pyownet and ow. sudo apt-get install python-ow sudo apt-get install pyownet #NOT FOUND SO USED: pip3 install pyownet wee_extension --install weewx-owfs.zip Even before all this, my i2c-1 (Sheepwalk rpi3v2) was serving up the 4 DS18B20's I hooked up to my browser at http://192.168.2.108:2121/ It is just that the weewx 4 that crashes with the above errors. I cannot follow the rest of these notes about weewx4/python3/buster problems. I've about got your readme.txt memorized. Also, my station type will not be OWFS, it will be a Davis and extra measurements will be gotten through the i2c-1 ow device. Rebooting one last time...
