Unsure I understood everything, does that mean that there's a "volatile" flag saying that value has changed and thus could trigger re-read of the value ? According to what I read in the docs temperatures are cached for 15 seconds. ( http://owfs.org/index.php?page=what-is-uncached ) Or that we could have a script polling only those volatile values ?
