Attached is a screenshot that shows the HOBOware error values displayed when a smart sensor is disconnected from a smart sensor-compatible logger, specifically the HOBO H21-002, U30, and H22-001.

When one of these loggers is launched with smart sensors attached, the logger expects a response from each of these sensors each time it takes a measurement. If the sensor does not respond, the value -888.88 is inserted into that data point. This informs the user to check for damaged or disconnected sensors.
