Hass.io xiaomi_miio error

Hi,

I just set up hass.io 70.1 (69.1) for the very first time on a Pi 3b and I got the following error upon start:

Error while setting up platform xiaomi_miio
Traceback (most recent call last):
  File "/usr/lib/python3.6/site-packages/homeassistant/helpers/entity_platform.py", line 129, in _async_setup_platform
    SLOW_SETUP_MAX_WAIT, loop=hass.loop)
  File "/usr/lib/python3.6/asyncio/tasks.py", line 358, in wait_for

    assert construct.version_string == "2.9.41"
AssertionError

I use the Xiaomi Philips Eyecare Smart Lamp 2 - it does not show up. I checked it on my hassbian (70.1) installation and everything works - really no idea. Theres also a 10 seconds warning right before the one above.

light:
- platform: xiaomi_miio
  name: Xiaomi Philips EyeCare
  host: xxx.xxx.x.xxx
  token: super-secret-token-that-works-on-hassbian

I wanted to downgrade/upgrade the underlying library but I have no idea how to do this with hass.io. SSH is driving me crazy…

Help appreciated, thx!
