The IoT operating system would help link smart home appliances made not only by Midea but also by other manufacturers, providing an all-new solution to smart home appliance ecosystem, said Xiang Jiangxu, vice-president and chief technology officer of Midea IoT.

"The IoT operating system would help reduce costs of linking between different products and brands and increase coordinative innovation in the smart home appliances industry," said Xiang.

The system was launched during Midea's intelligent conference, which was held recently in the company's innovation center in Foshan, Guangdong province.

"For users, the system would help realize the distributed and independent collaboration between various home appliances, providing more convenient and intelligent services," Xiang said.

In September last year, Huawei unveiled an updated version of HarmonyOS 2.0, which is designed for the era of internet of things, and it can be used in devices such as Huawei's smartwatches and in-car systems, as well as home appliances from third-party companies.

In an early interview in May, Xiang said the HarmonyOS operating system would cover almost all categories of Midea's products, namely about 200 varieties within this year.
