Take control of your comfort with the LinkedGo ST802-B smart thermostat powered by Shelly, designed for complete HVAC management, including underfloor heating, fan coils, ventilation, and cooling. Whether you’re managing a single room or integrating into a larger HVAC system, it offers advanced automation to keep your environment perfectly balanced and energy-efficient.
Featuring the ShellyX chip, this product offers complete Shelly capabilities, ensuring seamless integration with leading smart home systems. With built-in WiFi and Bluetooth, it connects directly to your network without the need for a hub, and even acts as a WiFi range extender and BLE gateway for your smart home ecosystem.
This versatile thermostat directly controls underfloor heating valves, supports fan coil units, and manages AC or DC ventilation fans, including 10V DC fans via its analogue output. For electric underfloor heating, it can work with a connected Shelly relay, automatically adjusting heat based on your chosen temperature. RS485/MODBUS support allows integration into larger, centralised HVAC systems, offering professional-level flexibility.
Safety and precision are at the heart of its design. The anti-freeze function maintains a minimum temperature during long absences to protect your pipes from freezing and bursting. Built-in humidity sensing, along with temperature and humidity offsets, ensures accurate readings and optimal climate control throughout your home or office. Future support for external temperature sensors will further enhance its ability to manage larger spaces effectively.
Thanks to full Shelly capabilities, you can create smart schedules and scenes to heat, cool, or ventilate only when needed, based on time, sunrise/sunset, or in automation with other devices, helping you save energy and lower your bills. The simple, intuitive interface keeps the focus on what matters: setting the perfect indoor climate effortlessly.
Highly compatible and future-ready, it integrates seamlessly with the Shelly Smart Control app, most automation platforms, and open protocols, giving you even more ways to take charge of your HVAC system with ease.
