While Google, Amazon and Apple get the most attention for their smart home hubs and speakers, plenty of other companies are making top of the line products that can be incorporated into a smart home ecosystem. Sonos is listed on CNET's best smart speakers, while Wyze is among the best smart plugs as well as offering great smart lightbulbs. Many companies, like Sonos, have made smart versions of products they've long made. Honeywell makes a quality smart thermostat and several of the best smart locks come from companies that have made locks for decades.
