Hi, do i need 32D or 32U board? And is it possible to add multiple thermometers in 1 config?

Hi, I want to buy some of these sensors, do I need also a WiFi+ble dev board or I can pair the sensors directly to my raspberry?

Hello, nice tutorial!
It is possible to add LYWSD03MMC on Pi3 with Home Assistent? I have fail to integrate. My sensors.yaml configuration is :
- platform: mitemp_bt
mac: "A4:C1:38:AA:DC:14"
monitored_conditions:
- temperature
- humidity
- battery
