Summary
A 6-in-1 Z-Wave 800 sensor that monitors motion, temperature, humidity, light, dew point and mould risk. Runs on batteries for up to two years or on USB-C power, and gives a 120° motion field of view for lighting, heating, ventilation and security automations.
Six Sensors in One Compact Device
MultiSensor 8 combines motion, temperature, humidity, light level, dew point and mould-risk sensing in one small Z-Wave 800 device. Instead of fitting several sensors to a room, one MultiSensor 8 gives your smart home everything it needs to switch lights, manage heating and ventilation, and react to movement. It mounts neatly on a wall, on the ceiling or in a corner, so it blends into any room.

Spot Mould Risk Before It Starts
Damp and mould usually start where warm, moist air meets a cold surface. MultiSensor 8 calculates the dew point from live temperature and humidity readings and warns you when condensation and mould become likely. Link it to an extractor fan, dehumidifier or heating control and your home can act automatically – ideal for bathrooms, kitchens, bedrooms and rented properties where damp is a concern.

Smarter Lighting, Heating and Ventilation
Use motion and light level together so lights only come on when a room is occupied and it is actually dark. Use temperature to fine-tune heating room by room, and humidity to run fans only when they are needed. With a 120° motion field of view, MultiSensor 8 covers a typical room from a single corner position, saving energy without you having to think about it.

Z-Wave 800
Built on the latest Z-Wave 800-series chipset, MultiSensor 8 supports standard Z-Wave Plus mesh networking, with S2 security encrypting every message. The 800 series brings better battery efficiency and reliability.

Battery or USB-C Power
Choose the power option that suits the location. Run MultiSensor 8 on two CR123A batteries for up to two years under typical use, or connect a USB-C cable for permanent power where a socket is close by. The USB-C cable and mounting accessories are included in the box, so it is ready to install straight away.

Works with Your Z-Wave Controller
MultiSensor 8 works with certified Z-Wave controllers, including popular platforms such as Home Assistant, Hubitat and Homey Pro. Add it to your network in a few steps, then use its readings in your own automations and dashboards. In the box: MultiSensor 8, wall mount, USB-C cable, batteries, mounting accessories and user manual.
