&gt; toothbrush<p>Incentive for dentists to recommend their internet enabled toothbrush so they can suggest specific brushing plans and monitor how well the person has been adhering to their regular brushing. There might also be some software on the dentist side for managing all of this.<p>I have one of these toothbrushes, that&#x27;s roughly pulled from the features section of the manual. (I have it because I can track how well I keep to brushing my teeth over time, well worth the ounce of prevention.)<p>&gt; thermostat<p>The local power company has a program where they supply a smart thermostat that they can regulate during peak use. With certain caveats of course, I think you can opt out of the automatic regulation several times a month.<p>&gt; fridge<p>Haven&#x27;t seen a practical use for this yet.
