Additional information

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

      return (float)pressure;

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.
