Since a few days back I have lost one 1wire sensor. Still registering the other 4 sensors but one refuses to come back.
Logs shows the following

Code: Select all

2016-01-03 11:40:16.479 (1 Wire) Temp (Sovrummet 2)
2016-01-03 11:40:17.972 (1 Wire) Temp (Vardagsrummet)
2016-01-03 11:40:19.353 (1 Wire) Temp (Källaren)
2016-01-03 11:40:20.733 (1 Wire) Temp (Sovrummet)

If I check /mnt/1wire I can see all 5 sensors and the one not shown in Domoticz is visible and temperature updated accordingly.

Code: Select all

ls -l /pi@raspberrypi ~ $ ls -l /mnt/1wire/

Setup->Devices gives (sorted by hardware, only 4 1 Wire sensors found)

Since the sensor failed I deleted it from the dashboard to see if that would help but didn't (of course), tried "Accept new Hardware Devices" and not to hide deleted sensor but still it's not shown in Domoticz.
Is it possible to debug the 1wire interface more between Domoticz and OWFS?
Could it be that the sensor also reports some error codes and therefore not shown? (I don't think so since it shows the correct temperature in OWFS)

A long shot.
I think that domoticz reads the uncached version of the temperature from owfs. You are checking the cached temperature. Search the directory structure and look if you a temperature value in the uncached structure. If not your sensor network may have some problems. You could have bad connection or signal collision. The cached always have a value present.

Hope you get it working.

For a few days, 1wire by OWFS reading cached temeprature.
Pls download thje latest beta and test it.
