Additional information

I think the following technical details may be useful - https://smarthomescene.com/reviews/inkbird-e-ink-air-quality-sensor-iam-t1-review/

Currently the device is successfully integrated using the above information, but it does create a bit of an inconvenience that entities are attached to the BLE proxy device itself as its entities. It would be very useful and convenient to have this device as a separate device.

I started implementing it in https://github.com/Bluetooth-Devices/inkbird-ble/issues/34 / https://github.com/Bluetooth-Devices/inkbird-ble/pull/35 (the library used by HA for other natively supported Inkbird devices); the library however currently does not support GATT, that's why it's on hold for now.
