A determination is made that an instruction has to be sent for processing in the IoT environment. A set of devices is located in the IoT environment. The set of devices includes the device and each device in the set of devices can execute the instruction for a similar outcome. For each device in a subset of the set of devices, a set of factors is collected, including an image of a portion of each device. For the device, a first weight is assigned to a feature of the device extracted from an image of a portion of the device, and a second weight is assigned to a feature of another device extracted from another image of a portion of the other device. When the first weight is greater than the second weight, the device is selected from the subset as a target for sending the instruction.
