Slow data, worth waiting for

Continuous below. Updated by hand.

The public page will not pretend this logger is live. Each import will retain the original observation times and the date the batch was retrieved.

Published observations

The archive, honestly dated.

Lifetime opens the published archive. Recent windows can be empty between manual retrievals; that does not erase older measurements.
