I have a permanent pier which only holds the mount between astrophotography sessions.  That is, the scope, computer and all but the mount electronics come in after every session.  Among the electronics is a Unihedron SQM which is monitored and MPSAS values saved in the FITS header of each image.

I also have a Davis weather station which I monitor with my personal RPi based solution.  I see how I can add the data to allow weather monitoring in EKOS/INDI with the Weather Watcher driver.

Since I don't have any automation needs tied into the Weather Watcher, what value will I get out of this operation other than to be able to go to the appropriate INDI tab to see the current conditions?  Is anything, e.g., the ambient temperature added to the FITS header?
