A processing device executing a rules engine receives a notification of a first event on a first network-connected device. The processing device identifies a first rule associated with a first user account, wherein the first user account is further associated with the first network-connected device, and wherein the first event on the first network-connected device is an input for the first rule. The processing device determines that the first event satisfies a first criterion of the first rule and generates a first command for a second network-connected device also associated with the first user account. The processing device then transmits the first command to the second network-connected device on behalf of the first user account, wherein the first command causes the second network-connected device to perform an action.
