During 304, the monitoring server 134 obtains, from a second monitoring system, data from one or more sensors located at a second property monitored by the second monitoring system. In some implementations, the monitoring server 134 may obtain data from the one or more sensors 114a via the control unit server 104a located at the residential facility 102. For example, the monitoring server 134 may obtain a notification from the control unit server 104a in response to the control unit server 104a determining user 124a left garage door 127 open after arming the residential facility 102
During 306, the monitoring server 134 determines that the data from the one or more sensors does not match predetermined data that indicates a particular status of the second property. In some implementations, the monitoring server 134 determines that the data from the one or more sensors 114a received from the control unit server 104a, indicating user 124a left garage door 127 open, does not match predetermined data that indicates a particular status of the second property, e.g., a determination that all devices should be locked at the residential facility 102 when the residential facility 102 is armed.
