Wemo WiFi Smart Light Switch 3-Way review: One of the best ways to render a three-way circuit smart

Wemo has handily solved a frequent grievance lodged in opposition to smart mild switches: Many don’t assist three-way circuits, and the ones that do sometimes require the presence of a companion change at the different location(s) controlling the circuit, thus rising the price and the complexity of any set up.

The software program aspect of the setup was accomplished in lower than a minute.

Within the Wemo app, there’s admittedly not a entire lot to do. You can flip the lights on or off, rename them, or assign a customized icon or {photograph} to every change. Wemo’s scheduling system can also be fairly refined and succesful, and also you’ll even discover useful extras similar to an auto-off timer that may shut off the lights after a time you specify, ought to the children overlook.
