The Avatto WT598-1T1 is a wireless smart thermostat designed to manage gas and water boilers with ease. It connects via 2.4GHz Wi-Fi or RF433 through an included receiver, allowing you to control your home heating through the Tuya Smart, Smart Life, or Avatto apps. For those who prefer hands-free operation, it integrates with Amazon Alexa, Google Assistant, and Yandex Alice. This device features a large illuminated LED screen with adjustable brightness, housed in a durable ABS plastic casing measuring 133 x 120 x 80 mm. You can power the unit using three AAA alkaline batteries or a USB Type-C port, and since it requires no AC wiring for the thermostat itself, you can either mount it on a wall or place it on a surface using the provided stand. To ensure accuracy, the temperature calibration can be adjusted between -9.9°C and 9.9°C. Managing your energy use is straightforward with a 7-day programmable schedule that supports up to six time periods per day. The system offers automatic, manual, heating, and cooling modes, along with an anti-frost function to protect your pipes during winter. Additional practicalities include a child lock for safety and family sharing, so everyone in the household can adjust the temperature in real time.
