Stop wasting water and energy waiting for a hot shower. Traditional recirculation pumps run 24/7, driving up bills and wearing out equipment. The Rayzeek motion sensor is a simple, plug-in retrofit that activates your pump only when you enter the room, providing hot water on demand without the waste. It’s the logical, ‘dumb-smart’ solution for modern homes, using your natural prep time to ensure hot water is ready when you are, without the constant energy drain.

Voice assistants and smart apps have failed us in high-traffic areas like the mudroom. When your hands are full, you need instant, zero-friction illumination, not a 1.5-second delay from a cloud server. Hardwired PIR motion sensors like the Rayzeek RZ021 provide immediate, local control that works every time, without needing an internet connection, a charged phone, or a free hand to mash a switch.

Stop fumbling with your phone’s flashlight on the icy path to your detached garage. Learn how to properly illuminate the way without the expense and hassle of digging a trench. We cover the physics of light, the right hardware, and the correct installation strategy to create a safe, reliable “light bridge” from your house to your garage.

Leaving a light on in a crawl space is a fire hazard, while a burnt-out bulb is a safety risk. The solution is not better habits, but automation. The Rayzeek RZ021 motion sensor switch is a pragmatic, load-agnostic choice designed to handle the damp, dirty reality of crawl spaces, removing human error and ensuring reliable, safe lighting when you need it most.

Ever find yourself waving your arms in a dark copy room to turn the lights back on? This common frustration isn’t due to a broken sensor, but one that’s poorly configured. Learn how a simple screwdriver adjustment to your Rayzeek sensor’s sensitivity and timer settings can solve the problem for good, ensuring reliability over aggressive, counterproductive energy savings.

Retrofitting smart switches into older homes often fails due to shallow metal electrical boxes that cannot accommodate bulky modern devices, creating a fire hazard and violating electrical code. Rayzeek switches are designed with a smaller form factor, making them the ideal choice for these challenging installations, ensuring a safe and secure fit without requiring demolition or compromising on functionality.

Your pantry motion sensor light is stuck on, but it’s not a ghost. It’s a welded relay, a common failure caused by the massive inrush current from your LED driver. This happens when a switch designed for resistive loads meets a modern capacitive load. We explain the physics behind this failure and why choosing a robust, motor-load-rated switch like the Rayzeek R-800 is crucial for a reliable lighting setup.

Relying on memory or consumer smart home gear for UV-C safety is a recipe for disaster. This article explains why latency-prone ‘smart’ automations are dangerous and how to properly engineer a kill-switch using industrial, normally-closed logic and physical interlocks to build a system that protects you from your own mistakes.

Are your security lights flashing for no reason on cold nights? The culprit is likely steam from a nearby dryer or furnace vent, which creates a large heat signature that tricks the sensor. The solution lies in adjusting the light’s position or physically blocking the sensor’s view of the exhaust plume.

In student housing, tenants with included utilities often misuse the AC, costing property managers a fortune and damaging equipment. A commercial-grade controller with hard limits and occupancy-based setbacks stops the energy bleed without relying on unreliable WiFi or tenant cooperation.
