Previously I have just used DS18B20 without any problem. When I added DS2408 I got problems, first I can not read values, but also on owhttpd I have errors:

PIO.0 Error: No such file or directory

I have upgraded owfs to 3.1 and added second I2C/1wire controller. Now owhttpd gave no error, but Openhab reports and errors every refresh time :frowning:
I have reinstall owfs x3 times, reconnect all sensors, tried to disconnect most of them, change DS2408 and still same problem, errors during reading.

Can such log tell more where is the problem ?
Any suggestions ?

Hi, did you find any solution? I have the same problem now. Thank you

In fact it can be cause by many issues, including hardware. I have check with two diff 1W interfaces and same issue. Then I took second SD, installed owfs +OH - no issues. Finally I have removed (on my main SD) owfs and install again, it works well :slight_smile:
