Support for BLE-only devices?

Describe the issue

Do you plan to support BLE-only devices in future? I have a Govee H6127 BLE light strip which is detected by Govee to MQTT and also shows up as a device under the MQTT integration but is non-functional. So it would be nice if such devices could also be controlled via Govee to MQTT in future.

It's labor intensive and requires reverse engineering each device. I don't have any devices that I care to spend that time on for myself, and I am less motivated to do it for others. I'm open to the idea of it if sufficient sponsorship and funding is provided. The scope of the work is:

• Figure out the build and deployment story for enabling BLE to work in the context of an HA addon
• Figure out how to get BLE reliably enumerating in a timely fashion, and a connection/control strategy. It is not feasible to remain connected to the device long term, but there will need to be some heuristics around retaining the connection for a short period after a control/poll so that subsequent interactions are faster
• Figure out whether and how HA BLE proxies work with this
• Obtain and configure a BLE sniffer device
• Then for each device:
  • Obtain the device that needs to be reverse engineered
  • Capture the traffic and reverse engineer the functions from the Govee app

What about the BLE devices that use the Gateways?

If they work with the platform API already, then they work already. Otherwise: I have no idea as I don't have one of those devices and I don't recall seeing any documentation about whether they will work with the supported APIs

I just checked and its not per govee's devices listed in the API reference I do see these ble water sensors Discovered in the log file, not sure if that means they can be controlled

as it says, it's not able to be controlled as it is a ble-only device

Alright, I will bug govee and see if they can add support
