Make sensor status tri-state #32
Description
The Sensor status flag may not represent a binary sensor good / sensor bad value. Instead it may just indicate a temporary glitch while accessing the sensor. A better approach may be to monitor the sensor status flags and if they get set more than X number of times, report failure.
0 = Normal
1 = Triggered
2 = Failed
Where failed means that the flag has been set 3 or more times.
