WeMo Mini Smart Plug | $18| Amazon
WeMo smart switches are basically the atomic unit of home automation, and you can pick one up for just $18 today, the best price we’ve seen outside of Black Friday.
Despite its diminutive size, this includes all the same features as the full-sized WeMo Switch, including IFTTT support, Alexa compatibility, and an Away mode that will randomize your lights to deter ne’er-do-wells.
