Shelly LinkedGo smart HVAC thermostat

The LinkedGo ST802-B is a smart thermostat for HVAC that gives you full control over different heating, ventilation and cooling systems. Thanks to the integration of the ShellyX chip, the device is compatible with the Shelly ecosystem, allowing remote control, automation and easy integration with the most popular smart home platforms. The thermostat is suitable for controlling underfloor heating, fan-coil units, ventilation systems and cooling solutions.

Thanks to its built-in IoT chip, Shelly supports both Wi-Fi and Bluetooth connectivity and does not require a separate central hub. It can connect directly to a Wi-Fi network and is compatible with the Shelly cloud platform. Like other Shelly devices, it can operate without a factory cloud in local mode and integrates with various smart home platforms and hubs via REST API and MQTT integration.

It supports RS485/MODBUS interface, allowing easy integration into larger HVAC systems.

It supports smart timing, frost protection and the connection of external temperature and humidity sensors, ensuring precise and efficient climate control.
