If you mean that a sensor would send data when there is a change in temp or input state. It's not possible. Only 1-wire master can initiate communication. Lately there was discussion that some 1-wire/iButton slaves can do that but it's rather uncertain and limited to those few chips if it even works. So generally most popular DS18b20 has to be polled. -- Patryk ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
