Have modified the onewire #arduino
example to publish to a topic as well as serial automatically ever 60seconds. Handy for when you don't want to modify the Arduino code every time you add/remove a new sensor! It uses the Onewire ROM ID as part of the topic!
Code here on GitHub; (thx to the guys on stack overflow for the help)https://t.co/tSHLu2UsFw
See screenshot below of five temp sensors plugged in publishing to separate topics based on there ID.
