The best smart home device depends on your goals. For most people, a smart speaker or display is the best start because it provides voice control and connects many brands. If energy savings matter most, a smart thermostat can pay for itself over time. For security, a video doorbell or smart lock brings quick value.
If you want simple automation, smart plugs and smart bulbs are easy and low cost. The best choice is the device you will use every day, and one that fits your chosen platform so it integrates smoothly with future devices. Think about who will use it most, and pick something simple enough that everyone in the home will feel comfortable using it daily without frustration.
