Hi both,

  Thanks for you fast answers. I had the same idea in mind, lower CPU
Usage by removing that polling infinite loop and thus avoid useless
broadcasts when nothing changes.
The fact us that most of our users are using DS9490R adapters so it
seems to be a no-go, this might have helped in getting domogik on very
low end computers; I will stick to that infinite loop !

FWIW Domogik has a quite good onewire support and even more, feel free
to join us #domogik @ freenode and give feedback !
It would be rather neat to have a feature in owfs where all devices are updated on a rolling basis. To provide iNotify support, perhaps then only updating the value exposed in owfs if it has changed from the last update.

Managing a threshold for each sensor won't be atomic and is probably too complicated to be worth it, but such would reduce the notifications for small changes in, for example, temperature. Handling a series of small increments would also be problematic.
