Need help with DS18B20

[Ian]

My first thought is wiring, one of my 18b20’s wigged out the other day and that was the problem.

My next thought is what is the RPi seeing-

DS18b20 not appearing in dashboard anymore

Might take a look at the RPi itself and see what it is getting from the sensor. cd /sys/bus/w1/devices/ ls cd 28-"put your serial here" ls cat w1_slave if you get something that looks like this, 25 01 4b 46 7f ff 0b 10 65 : crc=65 YES 25 01 4b 46 7f ff 0b 10 65 t=18312 the last number, 18312 in my case, is the temp in milli-Celsius. So in my case it is 18.312°C in my back yard. At least you will know if the sensor and RPi are working together. [image] My heartfelt thanks to pyromd76 ove…
