Those two warnings talking about ManagedThingProvider are concerning and might be relevant.
I also don’t see lines in the log at midnight that correspond to the Channels that represent the ones that are UNDEF.
The problem appears to be with the binding or the Thing definition. Let’s eliminate there begin something wrong with the Thing first.
Create a new Thing, this time using PaperUI, and link the UNDEF channels to some test Items. Let’s see if those Items get properly calculated. If that works, delete it and create a new one in the .things file with the same specifications as the one that you defined in PaperUI.
If those fail in the same way as your original Thing then we know that the problem isn’t necessarily with the Thing. Clear the Cache and then uninstall the Astro binding and reinstall.
If it still setting these to UNDEF, it’s time to How to file an Issue.
