Temperature logging is the natural companion to environment monitoring. When a rack monitor already tracks environmental conditions like temperature, recording that data over time lets you see trends rather than just a single reading. You can spot rising temps, hotspots, or cooling inefficiencies, and you can set alerts if temperatures drift above safe thresholds. This historical view is essential for maintaining equipment reliability and planning cooling and capacity.

The other capabilities—power metrics and video surveillance—address different domains (electrical performance and security, respectively). Door switch monitoring is already provided, so repeating it wouldn’t add new value.
