and receive a second set of data from a second electronic device, wherein the first electronic device and the second electronic device are manufactured by different vendors; receive a third set of data acquired from a third electronic device configured to monitor at least one of the property of a smart home environment, wherein the electronic device and the third electronic device are manufactured by a same vendor; and a processor configured to: determine a first trust value for the first set of data based on a first corroboration of the first set of data using the second set of data, wherein: the first trust value indicates a degree to which the first set of data has been determined to be accurate; the first corroboration comprises using the second set of data to verify the first set of data; and an activity is performed by the second electronic device within the smart home environment at least partially based on the first trust value; incrementally increase and incrementally decrease the first trust value based on corroboration of additional data obtained from the first electronic device; and determine a higher trust value for the third set of data as compared to the first set of data and the second set of data because the third electronic device is manufactured by the same vendor as the electronic device. ### Claim 7 (depends on 6) The electronic device of claim 6, wherein a fourth set of data from one or more sensors disposed on the electronic device is collected, and wherein the processor is configured to update the first trust value based on a second corroboration of the first set of data using the fourth set of data, wherein updating the first trust value comprises incrementally increasing or incrementally decreasing the first trust value. ### Claim 8 (depends on 7) The electronic device of claim 7, wherein the first set of data comprises an estimated time until arrival to the smart home environment and the second set of data comprises occupancy information associated with the smart home environment. ### Claim 9 (depends on 7) The electronic device of claim 7, wherein the first electronic device is associated with a vehicle and the second electronic device is associated with a garage door for the smart home environment. ### Claim 10 (depends on 6) The electronic device of claim 6, wherein the processor is configured to send one or more commands to one or more actuators of the electronic device based on the first set of data and the first trust value. ### Claim 11 (depends on 10) The electronic device of claim 10, wherein the commands comprise instructions configured to control one or more operations of one or more devices in the smart home environment. ### Claim 12 (depends on 6) The electronic device of claim 6, wherein the network interface is configured to: receive a fourth set of data from the first electronic device after determining the first trust value;
