I'm thinking if you can write another one supporting for the Mi BLE Temperature and Humidity Sensor #82

I haven't seen one of those sensors, yet. But I guess if there is an app, we can probably also reverse engineer the protocol. If you can send me such a sensor I'll give it a try.

I had some research on the sensor. Using OpenMQTTGateway on my ESP32, and found that the new sensor using the same tech with flora sensor, but different data format.

--------+s+++++++++++m+x--+l+++t+++h
s: Serial
m: BT Address
x: 0d
l: Length, 04
t: Temprature
h: Humidity

Temprature and Humidity are big endian.

I also have some x = 04 and 06, don't know what it meaning.

I think it does not make sense to add this to the miflora library, as it's a different protocol and a different device.

What might make sense is to share the BluetoothBackend wrappers, as you might also need that for this sensor...

You can use esp32 for this particular device. See here: https://www.youtube.com/watch?v=gyZjGOgDIRU
