LinkedGo Smart HVAC thermostat

The LinkedGo ST802-B is a smart HVAC thermostat that provides full control over various heating, ventilation, and cooling systems. Thanks to the integration of the ShellyX chip, the device is compatible with the Shelly ecosystem, allowing for 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 the built-in Shelly IoT chip, it supports both Wi-Fi and Bluetooth connections and does not require a separate hub. It can be paired directly with the Wi-Fi network and is compatible with the Shelly cloud system. Like other Shelly products, it can also operate without the factory cloud in local mode and be integrated with a range of smart home platforms and hubs via REST API and MQTT integration.

It supports the RS485/MODBUS interface, making it easily integrable into larger HVAC systems.

The device supports smart scheduling, frost protection, and the connection of external temperature and humidity sensors, ensuring accurate and efficient climate control.
