Huami Technology, known for its Amazfit-branded smartwatch, has partnered with Tesla and is preparing to unveil a new device that will be announced in China tomorrow, September 15th. Until now, it has not been officially confirmed which device will be released and what functions will be implemented in it. However, it is expected to be a smartwatch capable of controlling some of the functions of Tesla vehicles. Huami CEO Huang Wang has announced the announcement on Weibo, and the teaser suggests that the company is preparing to launch an updated version of the Amazift GTR smartwatch. The company recently updated the Amazfit GTR and Amazfit GTS smartwatches, now they can be used as keys for Xiaopeng P7 cars, the Chinese rival of Tesla Model 3. Thus, the presentation of a similar product with support for cars from Tesla will be a logical step.
