If you haven't already please see the section Oregon Scientific Modules section for basic info and setup information.

All Oregon units send an update every 30 seconds or so. Your Unit in XTension will only update it's value and run your ON script when the value changes. A Unit Property called “last message date” will be updated with each update received so you can check it for valid reception.

Depending on the unit many other extra data points may be available. In the case of this temp/thermo unit you'll see that the last message date is saved, as well as the channel switch setting. Many devices use the same packet format but XTension will provide at least a compatible device name if not the actual one of the device. This unit also sends a dry/comfortable/wet message called “humidity status” that could be ued to display generic humidity status.
