This weekend, I am going to replace my existing station(AcuRite 01036) with a Davis Pro2.

I would like to move the AcuRite to the garden area for some localzied readings? How can I transition the feed from the AcuRite to load it's data into the "extra" Temps fields in the database?

That would require writing a custom service that manages a separate thread which talks to your AcuRite.

Far simpler is to just run two instances of weewx: one for the VP2, the other for the Accurite, each with its own database. Then nominate one of the instances to run the reports, using the 2nd database in the reports. See the section Using multiple bindings in the Customizing Guide.

Wow. Thanks for the quick reply Thomas.

I'll look into your solution. Will that require each station to run on it's own Pi?

No, they can (and should) run on the same computer.

See the Wiki article How to run multiple instances of WeeWX for details.

Ok, got it.

I remember seeing that page a while back, but that was before I had started thinking about this.

So essentially, via the conf files, each instance will know which station feed, Davis or AcuRite, to pull from. And only one instance will be setup to produce the reports and it will bind to the second database for any of the AcuRite data points I want to use.

Makes sense. Now, to stumbled my way through it.

Fun stuff. Thanks for the great software. I will now return to the woodwork.

You've got the general idea. As implied by the Wiki article, make sure you specify different database names for the two instances. Otherwise, you'll two processes trying to use the same database.
