Zabbix saved us from a freezer incident
This morning my wife took something out of the freezer and for some reason the door was not properly closed. Unlike back in March 2022 during which a similar incident (but with an accidental power button push) started this while project, today nothing bad happened. We got alerts as soon as the freezer got too warm, and closing the door did resolve the issue in 15 minutes. Thanks, Zabbix!
