Can't read from small Xiaomi T&H Sensors

[pristis]

Hey,

Unfortunately can't read from small Xiaomi Bluetooth Temp & Hum sensors, known as LYWSD03MMC. There is the photo of the device: imgurl link

I have always this message:

Error polling device Bedroom BLE. Device might be unreachable or offline.

But for sure works great with MJ_TH_V1

If you have some idea how to read from LYWSD03MMC, I will be very grateful.

Don't you need to run a custom firmware to read the values?
