DONGGUAN, China — Huawei has launched its own operating system — the HongmengOS, known in English as the HarmonyOS, said the CEO of the Chinese tech giant's consumer division, Richard Yu, on Friday. Speaking at the Huawei Developer Conference in the Chinese city of Dongguan, Yu said the operating system can be used across different devices from smartphones to smart speakers and even sensors. It's part of Huawei's play in the so-called Internet of Things, which refers to devices connected to the internet. HarmonyOS will first be used on "smart screen products," such as televisions, later this year. Over the next three years, the operating system will be used in other devices, including wearables and car head units. Huawei said the OS will initially launch in China with plans to expand it globally, Yu said.

The United States placed Huawei on a blacklist — or the so-called Entity List — in May, which essentially restricts some U.S. companies from selling their products to the Chinese tech giant.

Following that move, Google said it suspended business activity with Huawei. But days later, the U.S. government eased some of those restrictions, and allowed Google to work with Huawei for 90 days. That timeline is almost up. The Chinese telecom equipment maker has previously acknowledged publicly that it had its own operating system in the works. Yu said the situation in regards to whether they can use Android is still "unclear" but that existing products that have been sold with Google's OS won't be affected by any ban. "We are waiting on an update," Yu said during a press conference after the launch.

How HarmonyOS works

HarmonyOS is open-source, which means that other device-makers could theoretically use its operating system. Making it open-source could help the OS increase its scale and attract more developers to make apps for it. Having a large number of useful apps is important for any OS to be successful. Yu said that "many" device makers "have strong interest" in using this OS, but declined to name them. He said he thinks today's operating systems — including Android and Apple's iOS — don't cater for the huge number of different devices that will be connected to the internet.

If we cannot use it (Android) in the future, we can immediately switch to HarmonyOS. Richard Yu CEO of Huawei's consumer division

The aim of HarmonyOS is to create a single software that will work across devices, from smartphones and laptops that have a large amount of memory and power, down to smaller hardware such as sensors, that require a lower bandwidth solution. In this way, Huawei hopes apps can work across numerous devices. That could ultimately help its business, as the company sells products from smart speakers to smartphones. Being able to control the experience across hardware and software could ultimately help Huawei create differentiated products. It's a recipe that has helped rival Apple find success.

'Convenient' to migrate to HarmonyOS

Yu told CNBC in May that the company's own OS could be ready for smartphones and laptops by the end of the year in China, and by mid year in 2020 for international markets. At the time, Yu stressed that the OS would only be used for smartphones and laptops if Huawei could not get access to Google's Android or Microsoft's Windows operating systems.
