DS18B20 not seen on the list of devices

Post by Adso76 » Monday 08 October 2018 19:48

Domoticz Version: 4.9895
Raspberry Pi 3 B+

I connected 1-wire temp sensor DS18B20 to GIO4

In shell everything seems to be ok:

cat /sys/bus/w1/devices/28-01131a4389b1/w1_slave

57 01 4b 46 7f ff 0c 10 38 : crc=38 YES
57 01 4b 46 7f ff 0c 10 38 t=21312

I added new hardware choosing 1-wire (system) as type and as I understood it should automatically appeared on devices list, but it didn't.

What could be wrong?

I found solution. When adding this hardware the field "OWFS Path" should be empty as "Sensor Poll Period:" and "Switch Poll Period:".

With this the new device appeared on devices list.
