Who is iHealthLabs?

Why has the website https://ihealthlabs.com.cn been taken offline? You can still find it in Google's cache though...

Search in Google for "site:ihealthlabs.com.cn". Look at the results. What is their connection to Xiaomi?

Why do they appear so frequently in Wyze's database? Why do we see wyzescale@ihealthlabs.com.cn? In order for these iHealth workers to do their job, wouldn't that mean all healthcare data of the beta testers would have had to be passed back to Beijing?
