it is brittle because of the dependency of one weewx instance upon another. not saying it won't work, it just introduces a coupling.
i prefer to have each weewx instance do its own thing, ideally using a generic, unmodified skin. then make an aggregated instance to unify everything, whether that is weewx, influx+grafana, mqtt+homeassistant, or any other aggregation. that way i can upgrade/update weewx instances without too much concern, and focus only on the aggregated report for anything customized i have done. i once ran a computer with 5 different types of hardware on it - one weewx instance for each weather station. then i ran the report generator as a cron job to pull all of the data into a single skin so i could compare sensors from all the stations. of course, eventually sunlight won and broke down the plastics in all of the anemometers, and salt air got into the battery compartments. but it was fun for a few years. i guess the uv damage was the real source of 'brittle' ;) > On Jun 3, 2025, at 13:10, vince <vinceska...@gmail.com> wrote: > > Not understanding why this is brittle.
