import binascii
from bluepy.btle import Peripheral

# find your switchbot address by
# pi@raspberry:~ $ sudo hcitool lescan
# replace "ff:..:ff"
p = Peripheral("ff:ff:ff:ff:ff:ff", "random")
hand_service = p.getServiceByUUID("cba20d00-224d-11e6-9fb8-0002a5d5c51b")
hand = hand_service.getCharacteristics("cba20002-224d-11e6-9fb8-0002a5d5c51b")[0]
hand.write(binascii.a2b_hex("570100"))
p.disconnect()

it's not working for me, but why?

• MagicSwitchbot
• Raspberry 3 Model B -> has Bluetooth Low Energy (BLE) on board
• Raspbian Buster -> bluez 5.50

cannot connect to the device no matter what I do. I also tried gatttool, nothing works...
Have you got an idea? Is an older version of the bluetooth stack needed (stretch?)?

same thing...no luck. does anyone have a solution to this problem?

I follow

Try entering your mac address with all lowercase letters, fixed this issue for me.

I can't even get that far on my RPI4 - I just entered the code as above but chaning my MAC number - no mistakes - yet...
