1. Overview
The YoLink Smart Thermostat is designed to provide advanced climate control for your home, now compatible with heat pump systems. It leverages YoLink's proprietary wireless technology, based on Semtech's LoRa, offering low-power consumption, long-distance coverage, and anti-interference capabilities. This ensures a reliable and secure IoT network for your smart home.
The thermostat requires a YoLink Hub for internet connectivity (wired Ethernet or 2.4GHz Wi-Fi), which is included with this model. Manage your home's temperature and mode from anywhere using the convenient YoLink app on your Android or iOS device. The ECO feature allows for automatic temperature adjustments to optimize energy savings, particularly useful when you are away.
