if they are all on the same box, then cheetah tags can point into another weewx database for values e.g. in my weewx.conf. if i have another database with data_binding ‘wx_other’, i can have tag day.outTemp.max(data_binding=‘wx-other’)
i have a weewx instance ‘wxrep’ that only exists to pull data from other instances to present a consolidated whole ⊣GE⊢ > On 21 Feb 2026, at 8:19 pm, 'Tomasz Lewicki' via weewx-user > <[email protected]> wrote: > > I have the following idea and problem at the same time.
