How do i add VeSync devices without cloud reliance?

how do i get my VeSync devices to talk to home assistant so i don’t have to deal with VeSync servers going off line.

Same question. I’ve got a Cosori tea kettle that uses BlueTooth and I’m wondering if I can get HA to interact with it.

Curiously, I set it up initially with my wife’s iPhone using the Vesync app. I then installed the Android version onto my phone and logged in with her account. Her phone is no longer on-site and somehow my Android phone is still capable of controlling the Kettle. I’m assuming there’s something other than regular ‘paired bluetooth’ involved here? Might that same thing be possible from HA using BT hardware? Right now I have no BT interface on the HA install (it’s inside a VM)
