The Sonoff SNZB-01P is a compact Zigbee 3.0 wireless switch designed to trigger smart scenes or control connected devices throughout your home. This small white button is made from durable PC material and measures 45 x 45 x 17.7 mm, making it discreet enough to place anywhere. It supports three distinct interaction types—single press, double press, and long press—which allows you to assign different commands to a single switch via the eWeLink app. Weighing only 27.8 g, the device is powered by a CR2477 battery that can last up to 5 years, reducing the need for frequent maintenance. It works seamlessly with the SONOFF NSPanel Pro, ZB Bridge Pro, and ZBDongle-E, as well as other standard Zigbee 3.0 hubs, and can be integrated with Amazon Alexa for voice-assisted automation. Because it operates in temperatures ranging from -10 to +60 C, you can reliably use it as a general device controller or even as an emergency alert button in various rooms.
