At my lab i have only one sensor - DS18B20
The Raspberry has standard kernel driver for 1w interface. And it has
mounted folder /sys/bus/w1/devices where i can also read temperature value.
Directly from file (for ex. /sys/bus/w1/devices/28-05de7fdc/w1_slave)
Today (24h) with script I tested r
I also have periodical problem on RPI 1 with owfs. I received periodically
UNDEFINED value from ds18b20
and I solved the problem by refusing this component.
you can easy get value from sensor using http binding with cgi-bin requests.
now - all work correct and stable
