Hello,
but the "simultanues/temperature bit" Need external powered sensors as i suggest.
So what is when you have sensors with paratite-power?
And i suggest that you will Trigger the simultaneous/temperature bit manually in your
external application. Not directly inside the OWFS code.
Best regards,
Roland

- Read all temperatures
- Set the simultaneous/temperature bit
- Perform logic operations, setting outputs to devices based upon temperatures read, etc
- Log values to database
- repeat.....
OK ignore the first loop. The logic and logging takes more than 1 second, so when I read the temperatures they are all converted because it was initiated at step 2 on previous loop, no wait time and no 85 degree readings.
I agree that there is a design fault with the DS1820, but it is nothing we can fix here, and Dallas are not going to do anything about it now.
Hope that helps a bit

I will read over OWLIB from the OWSERVER values out (Let me say the program collectd will read it with the onewire plugin). I have also not all my sensors (Type 28 = DS18B20) external powered, so the simultanues read of values will not work. On this way the value of latesttemp will be only updated, when the sensor is read on an second way. Only latesttemp will hold his value without any changes. So it is not (For me) complete right working as i was suggesting, that the update of that value will be also made. But this will be never be done.I'm sorry, I do not understand from the above what your problem is.
