How you'll go about this varies from gadget to gadget, but the update process should be fairly straightforward on all your smart devices. When you first set up this gear, you should see an explanation of how it installs updates. In a lot of cases, this now happens automatically, so you won't have anything to worry about. For instance, with an Echo device, Amazon will apply its updates automatically overnight, and you can manually check whether a refresh is pending by saying, "Alexa, check for updates." If you're not sure what to expect, check the instructions that came with your device or visit the support section of the manufacturer's website for more details. In another example, when a Philips Hue light has an update in the wings, it sends you a message through the official app. You can then choose to apply the new software right away, or to receive another reminder in a week; we'd recommend going for the first option.
