1. A monitoring system that is configured to monitor a property, the monitoring system comprising:
a sensor that is configured to generate sensor data indicating a first environmental condition of the property;
an electrical monitoring device configured to:
couple to an electrical cord that provides power to an electrical device located at the property, and
generate electrical data indicating an electrical characteristic of the electrical cord including a time duration that the electrical device has been powered on; and
a monitor control unit that is configured to:
receive, from the sensor, the sensor data that indicates the environmental condition of the property;
receive, from the electrical monitoring device, the electrical data;
access, for each of one or more environmental conditions of the property that include the first environmental condition of the property, respective calibration data including expected values of the electrical characteristic of the electrical cord;
select, from the calibration data for each of the one or more environmental conditions of the property and using the sensor data, one or more expected values of the electrical characteristic for the first environmental condition of the property;
determine, using the electrical data, that the electrical characteristic of the electrical cord deviates from the selected one or more expected values of the electrical characteristic including determining, using the electrical data, that the time duration that the electrical device has been powered satisfies a threshold time duration; and
in response to determining that the electrical characteristic of the electrical cord deviates from the selected one or more expected values of the electrical characteristic including determining that the time duration that the electrical device has been powered satisfies the threshold time duration, perform a monitoring system action.
