In his Oscar acceptance speech, Leonardo DiCaprio made clear that his interests go beyond European supermodels. Namely: the environment. Here’s more evidence: he’s an investor & advocate for Zuli Smartplugs. These plugs are used to automate home appliances as well as switches & thermostats. A network of at least 3 plugs will link with the Zuli app to detect your presence in the home or space, turning on & off accordingly & saving energy.
