When I put the try: except: finally: back in, weewx never runs, I get the syslog entry of
*systemd[1]: weewx.service: Main process exited, code=exited, status=1/FAILURE* I have to comment out the try: except: finally: out of my extensions.py and it runs normal. I do not have a clue why, every once in a while (~once/week), a read statement picks up a text value from a temperature file and reads it in with extraneous characters. I've checked the source file (I have a history .log which has all the readings & their date/time in it) and that file at the point where that instance of the temperature is, does not have anything extra.
