I wouldn’t recommend using the get-address and get-temp-c nodes in the same patch. When working with multiple thermometers I think it is best to first determine the address of each device using the example-read-address patch (see Multiple DS18B20 Thermometers on Single OneWire Bus - #6 by wayland). Then you will know exactly which thermometer you are reading when you use get-temp-c.
However, if you have to combine get-address and get-temp-c in the same patch, you can use the nodes in this xodball:
get-address-bytes.xodball (19.9 KB)
Example patch from xodball:
Don’t forget to use request-temperatures node to make sensors perform temperature conversion before reading temperature using get-temp-c node (see example-read-temp-multi-devices).
