There are several ways of accomplishing this. The simplest is just to run two different WeeWX instances, one for the Vantage, one for the Ecowitt. This will result in two different databases. Then combine them into one report. See the section *Using multiple bindings <https://www.weewx.com/docs/5.5/custom/multiple-bindings/>* in the documentation.
Another approach is as you say: write a service that extracts what data you want from the Ecowitt. This will require running a separate thread that does the data acquisition from the Ecowitt so as not to block the main thread. Run two instances and have them both publish to MQTT. Then run a third instance that subscribes to the MQTT broker and let it produce the reports. There are lots of possibilities! -tk On Fri, Aug 14, 2026 at 3:05 AM mihec <[email protected]> wrote: > Hi, > I have 10+ years database from Davis Vantage Vue which is still working > well.
