Rayzeek Occupancy Motion Sensor Light Switch, 5A, US, Neutral Required


The RZ021-5A-N motion sensor light switch uses an advanced passive infrared (PIR) motion sensor to detect people in the sensor zone and integrates a photocell for daylight sensing. Users can adjust the configuration by simply pressing the two push buttons on the panel without uncovering the wallplate. Besides occupancy and vacancy mode, the RZ021 series motion sensor switch introduces an innovative manual ON/OFF mode allowing the sensor switch to be used the same as a manual wall switch so that users can have manual override and keep the light always ON/OFF as long as needed. The RZ021 series is a direct replacement for the US standard 1-Gang wall switches. A neutral wire is required for RZ021-5A-N.

  • Versatile Sensor Mode: Occupancy(Auto-ON, Auto-OFF), Vacancy(Manual-ON, Auto-OFF), Manual ON/OFF(Manual-ON, Manual-OFF)
  • Broad Voltage: Applicable for 110V residential and 277V commercial voltage in the US.
  • Flexible Wiring: Hot wire, Load wire, Neutral wire and Ground wire. (Can be installed without a neutral wire with RZ021-5A-G)

Ever meet these problems?

manual mode solution for home pets

Energetic pets trigger the sensors in the middle of the night

In the middle of the night, dogs and cats are highly energetic while people are sleeping. They often trigger occupancy sensors with bright light waking us up, especially in laundry rooms or the kitchen where lies the litter box.

Is there a super-easy way to temporarily keep the light always off during the night and return to occupancy mode in the day for a night of good sleep?

manual mode solution for air bathroom

Lights turn off while no motion detected in a shower

The occupancy motion sensor in our bathroom detects motion to keep the light on in the shower. In occupancy mode, the light usually goes off as it’s hard to detect motion due to installation position and heat change. Even in vacancy mode with 30 minutes time delay, the light might still go off when we want to enjoy a nice and long hot shower, changing time also takes extra steps.

Is there a way to keep the light always on in the shower without the embarrassment of constantly waking up the light?

Embrace a smarter lighting control

Magically works like a regular switch when in need

Rayzeek introduces a breaking new feature to solve the problems in the above scenarios, the innovative manual on/off mode.

In this mode, the switch will temporarily become fully manual operated just like a normal mechanical switch, which allows users to keep the switch always on or always off without the distraction of motion sensors.

And It’s super easy to operate.

Press the small button on the panel to enter manual mode and press again to get back to the sensor mode without losing any settings.
