Want instant, reliable motion-activated automations — without cloud delays or Wi-Fi issues?
The SONOFF SNZB-03P is a Zigbee 3.0 motion sensor that connects directly to your Home Assistant Zigbee network for fast, local, battery-friendly detection. Use it to trigger lights, secure entryways, save energy, or automate hallways and bathrooms with zero lag.
Want your smart home to know you’re still in the room — even when you’re sitting still? The SONOFF SNZB-06P Zigbee Human Presence Sensor uses 5.8GHz mmWave radar to detect motion, micro-movement, and true human presence far more accurately than a PIR sensor. It connects directly to your Home Assistant Zigbee network for fast, local, Wi-Fi-free automation, keeping lights on while you’re present and turning them off the moment you leave. It’s perfect for bathrooms, bedrooms, offices, and any room where traditional sensors fail.
Door and window contact sensors are hugely versatile and can be used in a number of home automation scenarios. These sensors often consume very little power and can run off of a single battery for many months.
Two popular options for motion detection in smart home systems are Passive Infrared (PIR) sensors and millimeter wave (mmWave) sensors. Each technology comes with its own set of advantages and drawbacks, making them suitable for different applications depending on the specific needs of homeowners. Let’s delve into the pros and cons of each:
A Passive Infrared (PIR) sensors is specifically designed to detect changes in infrared radiation within their field of view. Passive infrared radiation can be emitted from certain objects or warm-blooded creatures such as humans and pets.
