Native Bluetooth

[BlackandBlue1908]

I May be asking for the moon here but would be awesome if this could use the new native Bluetooth integration. Could circumvent the need for the hubs altogether and give full local control.

This is not something I have plans to investigate, however I will leave the issue open; I imagine you won't be the first or last to request this 😄.

It may also be helpful as a future reference should anybody wish to collect or share any reverse engineered bluetooth dumps that could be used to implement this request in the future.

I love to see this implemented. I have been having some cloud latency with this recently.

@sebr Thank you for developing this integration. I just picked up an XD and Gen 2 hub since I knew I could get it into HA because of this.

I know this issue requesting Bluetooth was opened before most of HA's work on expanding Bluetooth support at the end of last year. Would any of that development work make it easier to add Bluetooth support for this integration?

@GitHubGoody, I haven't investigated the progress of HA's native Bluetooth support. This is partially because I don't have any plans to reverse engineer B-Hyve's Bluetooth protocols or reimplement them in HA.

[GizmoGoody]

OK. NP. I figured I'd check before opening the hub. Thanks.

I took a cursory glance at it.
I've recently built a HA Bluetooth integration for my fireplace utilizing ESPHome Bluetooth proxies, so my memory of the implementation procedure is still fresh.
It should be possible to reverse engineer the protocol.
Bluetooth communication is encrypted using AES ECB without padding (so it's pretty insecure as far as I can see). The encryption key can be seen at https://techsupport.orbitbhyve.com when viewing a device. It will show up Base64 encoded as the "Network Key" under Mesh Details. I don't have experience dealing with the Mesh bit of the BLE communication, so I haven't looked into that.

For anyone still watching this issue..I published a separate BLE-only HA
integration specifically for the B-Hyve XD (24634, BLE-only, no WiFi hub):

https://github.com/wxfield/Orbit_B-Hyve_4Port_Controller

It's a standalone custom component (not a fork of this repo, since the
control surface is fundamentally different..pure BLE GATT vs. cloud
WebSocket). HACS-installable. All 4 zones working in HA, no hub, no cloud
at runtime.

Tested against firmware 0107. The wire protocol is fully documented in the
repo's docs/ directory..the gotcha that ate the most time is a
content-dependent 16-bit trailer checksum on every frame that the device
silently drops if mismatched.

Won't help you for the WiFi-hub-paired models that this repo targets, but
might be useful for anyone landing here with the BLE-only XD.
