Smart-home devices sometimes require complicated installation that just doesn’t make sense for renters. Plus apartments have different needs than single-family homes. That’s why we decided to outfit a whole condo with smart devices that don’t require rewiring or permanent installation. Each week, we’ll tackle a different category and look at various products, then explain how we made our selections. At the end of the series, we’ll examine the smart apartment as an ecosystem, and how all these devices do — or do not — work together.
