While a more expensive dimmable smart plug may offer more features, you may be able to find a cheaper option that still meets your needs.

6. Brand Reputation

When choosing a dimmable smart plug, consider the brand reputation of the manufacturer. Look for a brand with a good track record of producing high-quality, reliable smart home devices.
