Sorry, forgot to check back on this thread. Yes, Blueiris8 has it right. Putting "Tampered" right in the sensor's main bar is key possibly highlighting it is purely bonus at that point but would make it easier to visualize sensors in a bad state. In fact it would be excellent if that idea could be extended:
1) User customizable "alert" conditions for sensors. Ex: Any time a leak sensor is triggered, it would be in the "alert" state, or when my door sensor is open between the hours of X and Y or the alarms are set on by the key fob, or when motion is detected under similar circumstances.
2) Alert method is user customizable. Maybe notification. Maybe by highlighting the the sensor's bar a color. Maybe moving that sensor up the list to be more noticeable.
3) Alert priorities. Set which ones take precedence. Ex: Maybe you care more about the fire alarm than the door being opened (to get out) in the middle of the night.
