WiFi-operated smart thermostat with advanced features

Take control of your comfort with the LinkedGo ST1820 smart thermostat powered by Shelly, designed for precise management of heating systems. Whether you’re using water-based or electric heating, it offers advanced automation to keep your home warm 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 thermostat directly controls heating valves, supporting up to 2A resistive or 1A inductive loads, and features a dry contact relay to signal your gas boiler, pellet stove, or other heat sources to switch on and off as needed. It also supports electric underfloor heating by working with a connected Shelly relay, automatically adjusting heat based on your chosen temperature for maximum flexibility across different heating setups.

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, as well as temperature and humidity offsets, ensure accurate readings and optimal climate control throughout your home.

Thanks to full Shelly capabilities, you can create smart schedules and scenes to heat your home 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 room temperature 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 heating with ease.
