Class Ds18b20Thermometer

The path of the file the thermometer reads.

The serial the kernel named the thermometer's directory after: the twelve hex digits after 28-, which tell one probe from another and stay with the part for life. Null when the file does not sit in a DS18B20's directory, as one named by at may not.

Reads the file on a worker thread, which makes the kernel run a conversion, and resolves with the decoded reading. Rejects when the file cannot be read or the kernel or this decoder rejects the checksum.

A thermometer named by the path of its w1_slave file.

Every DS18B20 the kernel has found, one per 28- directory under devices, which is /sys/bus/w1/devices unless given. Throws when the directory cannot be listed, which usually means the 1-Wire overlay is off.

A thermometer named by the serial in its directory name, the twelve hex digits after 28-.
