I am using your 1-wire board on a PI2 since some months. Now I replaced PI2 with a PI3.
Additionally I went to Jessie Lite version of Raspian.
For some days everything was working fine. Now I lost the connection to the temperature sensors.
I reinstalled the owfs software. i2cdetect -y 1 shows the board on address 18.
Still no sensors in the mount point.
What happened? Is there a defect on the board and how could I check the functionality?
Reboot, disconnect from power ... I tried everything.
