There are three functions of controlling the IOT smart lunch box. First of all, customers enable to input heating or cooling time on wechat program to commend the lunch box. While heating or cooling work is done, you will receive a message on wechat small program to remind you of enjoying the food. Next, customers can also input desired temperature of the food to control the lunch box. Finally, customers can look up recipes though our wechat smart program.
