The cache has a known lifetime -- default 15 seconds for "volatile" data (like temperature readings). This can be bypassed (uncached directory) or changed to a different timeout.
One approach might be to have you fast-polling control loop reading uncached, and your monitoring thread reading cached data. (Reading uncached DOES update the cache).
