The Wemo Dimmer Wi-Fi Light Switch has just gone on sale for $49.99. This matches the lowest price it has ever been and is $30 off the regular price of $79.99. This is the same price it was during Black Friday last year and around Prime Day this year, so it’s unlikely to drop any further for Black Friday this year. This smart light switch replaces any standard light switch to give you remote control of the lights connected to the switch through the app or through voice using Alexa. If you have a room full of lights that are controlled by a switch, like recessed lights in a ceiling, it makes much more financial sense to add a single smart light switch like this one, than to replace all the bulbs with smart bulbs. This Wemo switch offers a few handy features even if you don’t plan to control it through the app or Alexa, such as a setting that lets you control what dim level the lights turn on to at specific times so you’re not blinded by bright lights in the middle of the night. It has great reviews and is the best-selling smart dimmer light switch on Amazon and it does not require any sort of external hub to work.
