Total noob på både 1-wire, linux osv till för någon vecka sedan då man började hänga här
Jag loggar två temperaturer , Inne och ute, har fungerat perfekt flera dagar men nu när det blir kallare ute så märker jag att jag får "läsfel" på utegivaren, har testat att tagit in den och då fungerar den som den skall, hänger jag ut den igen så fungerar det ända tills givaren blir kallare än +1 grad, då får jag ett fel, jag får iofs ett värde också men det loggas inte i databasen, Jag klistrar in lite hur det ser ut nedan så kanske någon kan berätta vad jag gör fel...
Det enda jag kan tänka mig är att den den kanske behöver mer tid på sig att läsa ut temperaturen när sensorn blir kallare/har ett lägre värde, men kan det verkligen vara så? Och vad göra i så fall?
Jag börjar med att köra följande:
modprobe fuse
/opt/owfs/bin/owfs -u --usb_regulartime /var/thh
Jag har även testat det ovan UTAN --usb_regulartime, samma fel då!
