Running Klimalogg and Fine Offset in one weewx session?

[Maarten Weerman]

Hi all, 

I have weewx 4.4.0 already running with a Fine Offset Station and it works fine. I also have a TFA Klimalogg station with two external sensors. I've read out that it is possible to get data with a weewx Klimalogg driver and that it is also possible two run two stations in one weewx session. 

I have some questions: I've read that the table structure of the klimalogg database is different from the "normal" weewx.sdb database. Does that have any effect when running two stations in one weewx?

And regarding the existing weewx.sdb table, do i have to rename it in e.g. "fineoffset.sdb" or can i keep the current name weewx.sdb? I still want to use my existing weewx.sdb database table for data from my Fine Offset Station and just add the "Klimalogg.sdb" database for the Klimalogg Pro.

Best regards

Georg

the Klimalogg Pro database consists of two databases (default names: weewx.sdb and weewx-kl.sdb) - they will have of course be located in a different directory from your standard weewx installation if you keep the database names.
The installation will not run with the weewx-kl.sdb only - even though the archived data will be in weewx-kl.sdb.
I found that out the hard way thinking for a restore only the weewx-kl.sdb was necessary. Luckily the KLP has a 50,000 record internal storage which could be reloaded when starting from scratch again.

You will have to run two separate instances of weewx and for each your SQLITE_ROOT should be different -  (if for you session = instance, then not one session).

As they are/will be located in different directories fed by two separate weewx instances (with their own weewx.conf - e.g. fineoffset.conf and klp.conf), you don't need to rename the databases - but you can.
maybe for a better recognition you should do this. (The weewx multi description uses the rename approach, see below)

If in your wording session = one weewx installation on one server, then you are correct.

By the way - I'm running both myself (weewx with GW1000 and weewx with Klimalogg Pro) - so far still on two separate RPi4s, but one of my next activities will be to move them onto one RPi4.

There is a setup description on GitHub for running two stations and two weewx instances on one server - recently updated.
