By publishing Henry's (my weather station + ISS) shortcomings here, he's decided not to come back to life despite a week in the warm and dry!

But......

I note the voltage on my 3 week old Duracell CR123A is already down to 2.98 volts?! Solar cell appears to function generating 2.1volts  when aimed at the sun and less when away. New battery 3.25volts. Supercap still no sign of leakage or bulging and has 2.57volts across it when all is connected. Green LED still flashing but console not receiving anything.

Will see if new battery kicks starts things.

Is this fall in battery voltage in such a short time significant? What might cause this? The Supercap? Are all Supercap failures visible/total shorts or are some more subtle?

Yes, it's significant - but it might just be that you purchased a battery that had been on the shelf for many years.  The new battery will be a good test.  Check the "install by" date on the package.

Yes, a supercap problem or other problem could cause the battery discharge.  Not all failures are visible, and not all or total shorts.  It may be time to contact Davis about this - "Green LED still flashing but console not receiving anything."
