    What is the best way to programmatically get notified of a arbitrary change in value of a given Pi tag?  Notifications?  Any other Way?


      We are looking to call a REST API when a given tag's value meets some arbitrary condition.


      What ways are there to do this?  We are currently querying the Pi database ever second or two, which adds latency and overhead.
