My suggestions:
- Never alter a released driver. If you do so, your changes will be overwritten every time you upgrade weewx. - Do all your custom things in extensions. They go into the bin/user directory and are upgrade safe. - Package your custom extension or skin in a format installable by wee_extension. Makes it far easier to manage. Lastly, weewx supports multiple databases which is a very powerful feature: - Have your custom extension(s) write to additional database(s) and specify which db to get the data from in your skins. How to configure weewx to do this is documented in the Customization Guide <https://www.weewx.com/docs/customizing.htm#Using_multiple_bindings> but there are lots of examples for how to do this. If you want to see one full-up example that is installable from via wee_extension you might want to look at my mem extension (github link) <https://github.com/vinceskahan/vds-weewx-v3-mem-extension> On Saturday, January 23, 2021 at 10:11:36 AM UTC-8 peterq...@gmail.com wrote: > I'm building a new thermostat and the controller (ESP32) has wifi.
