Question about Huawei Watch 3 Pro Elite (Galileo-L50E)

Hello Danito,
Well, I'm not sure about the watch directly. Bluetooth headphones are possible.
What I just saw is that the Polar H7 and the Sutuno Smart Belt are listed in the corresponding Health App from Huawei. So you can use them in combination.
I would ask about the Huawei customer service, as the range is constantly being expanded.

Sorry no idea ...
