One of the easiest way to conserve energy at home is to simply shut the lights off when you leave a room, but it’s easy to forget. So I like to compare this wireless occupancy sensor from Lutron to my dad, who spent most of my childhood roaming the house, turning off lights and lamenting about last month’s power bill. Thankfully the Radio Powr Savr (which also conserves the letter ‘e’ it seems) doesn’t come with a sermon about electricity costs, and will quietly turn on or switch off the lights whenever someone enters or leaves a room.
Since it connects to Lutron’s dimmer switches wirelessly using radio waves, installing the sensors doesn’t require any wiring whatsoever, not even power since the unit’s batteries are rated for 10 years before needing to be swapped out. It even has a test mode that will illuminate the unit when it detects that someone has entered a room, so you can easily find the optimal location to mount it. Of course all those savings do come with a one-time investment of $130, but over time it should pay for itself in theory.
