I spent a lot of time trying to get BLE mesh setup with these lights. The goal was to use something like a raspberry pi to connect to the lights (not using the included hub at all). Got somethings to work but was just taking too much time and not reliable. More about that here: BLE Sig Mesh Gateway - #5 by dberse
But I ended up getting the hub added to Smart Life and creating a cloud tuya integration and the lights are working now in HA. I did have them in Atomi app first and just followed the steps to reset the hub (hold the button down until the light blinks). Then I did have some issues adding the lights under smart life but eventually got it working, just hold the button on the light down for 10-20 seconds. Had to go back into Atomi app and remove a light before it would pair in smart life.
