Kitchen staff leaving walk-in cooler doors open for extended periods causes temperature issues and unnecessary service calls, and there is no simple way to monitor or alert on door open events.

Current temperature controls only monitor box temperature, not door open status, so technicians cannot prove that the cooling equipment is functioning correctly and that the issue is caused by staff behavior.
