News from the attic: it’s warm here. Raspberry Pi + 1wire thermometer. More details to come:

> cat /sys/bus/w1/devices/*/w1_slave
ee 01 55 00 7f ff 0c 10 02 : crc=02 YES
ee 01 55 00 7f ff 0c 10 02 t=30875

It means: 30.875 deg celsius, almost 89 deg F.

Update: 4 thermometers installed on same wire, working!
