I am using wall mounted onewire sensor in my brew setup. I have 4 DS18B20 in summary, but last time I wanted to brew, I realized that due to one sensor, the whole 1-wire bus goes down - which means no devices can be found in /sys/bus/1-wire/ …
Now, I measured 47 ohms between ground and signal line on the defectouos sensor. On my other sensors, I measure “infinite” resistance between signal and ground.
What would be the best way to open wall mounted sensora and check the sensor itself?
