By weewx4 I assume you mean python3 and weewx4? What are the sensors? Just temperature or...? You shouldn't lose anything. The driver does work with weewx4 and python3 I have it running with 4.0.b18 which was the last version? before the final release of weewx4. If you know your sensor_map and sensor_type then you are halfway there. Nothings changed in that respect. The biggest hurdle seems to be getting owserver to behave. You could try installing that now and when it runs okay then you'll be set. There may be an interruption if your existing owfs.py (with python-ow I assume) and owserver both point to the busmaster device and attempt a query at the same time (Gaz's was /dev/i2c-1, mine is the USB dongle). It may just simply block on access, or segfault but a restart of either service will fix that, nothing should break. When it comes to restarting services (keeping in mind that I use SysV eg: /etc/init.d/weewx) I no longer use restart. I actually stop them first (regardless of their state) then start them. I have more success that way, probably gives them a chance to regain state. If you do much the same as Gaz but stick with python2.7 then you can test it all before making the big shift to weewx4 running under python3 -- Cheers Glenn rorpi - read only raspberry pi & various weewx addons https://github.com/glennmckechnie -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
