Product detailed description

🌡️💧 Shelly Wave H&T – Intelligent Z-Wave 800 Temperature and Humidity Sensor

The Shelly Wave H&T is an advanced smart sensor meticulously designed for precise and continuous monitoring of temperature and humidity in your home or office. Utilizing highly accurate Swiss-made sensors, it instantly detects even the smallest environmental fluctuations, empowering you to maintain a perfectly healthy and comfortable indoor climate.

Built on the cutting-edge Z-Wave 800 Series platform, the sensor delivers a gigantic leap in network stability. Thanks to its exclusive support for Z-Wave Long Range (ZWLR) technology, it can seamlessly communicate with a similarly equipped control hub over an astonishing distance of up to 1000 meters (with direct line of sight). Say goodbye to signal dropouts in remote rooms or deep in the garden.

Energy Savings and Outstanding Battery Life

The Shelly Wave H&T is powered by a single standard CR123A battery (which is included in the package). The device is so incredibly energy-efficient that it can operate on this single battery for a mind-blowing 2 to 3 years. Another massive advantage is that you can easily switch the sensor to permanent USB-C power at any time (cable not included). This instantly enables much faster and more frequent reporting of climate data to your Smart Home system.

Why Choose the Shelly Wave H&T?

• 🌡️ Perfect Overview: The integrated high-contrast e-ink (electronic ink) display shows current readings clearly and legibly from any angle. It only consumes power during the fraction of a second when the numbers are redrawn on the screen.
• 💧 Mold Prevention: With highly accurate relative humidity (RH) measurement, you can automatically trigger your bathroom exhaust fan immediately after a shower, preventing dangerous condensation and the growth of harmful mold on your walls.
• 🔥 Smart Heating and Cooling: Use the live data from the sensor as the fundamental trigger for your Z-Wave heating relays and thermostats. You will always maintain the perfect ambient temperature while minimizing gas and electricity consumption.
• 📶 Gigantic ZWLR Range: When utilizing Z-Wave Long Range, it overcomes all previous limitations (reaching up to 80m indoors without any signal boosters, and 1000m outdoors). Perfectly compatible with Home Assistant (Z-Wave JS), Fibaro HC3, Hubitat, and SmartThings.
• 🔐 Military-Grade Network Security: All communication is strictly safeguarded by the Security 2 (S2 Authenticated) protocol featuring robust AES128 encryption. It also fully supports Over-The-Air (OTA) firmware updates remotely.
• ⚙️ SmartStart Inclusion: Simply unbox the device, scan the QR code into your smart gateway app, and the connection process will complete automatically and securely.

📝 Note: A Z-Wave control gateway (Smart Hub) is not included in the box. Your own compatible Z-Wave gateway is strictly required to configure and operate this device. The sensor does not connect directly to a Wi-Fi network.
