same here, updated today all my curtains to firmware version 3.9 and the position reading in Homey is now broken…
Strange enough my Homey version is on beta/test 1.0.8 and in the topic it is listed that the test(beta) version is currently at 1.0.6, so not sure if my app version is correct.
extra question:
is there any info regarding the API of the humidifier?
It still respond very late or only when power is switched on/off, i reported this as problem to switchbot months ago but they only reply that it a problem of the API developers. I reported the problem in github but that seems to be completely dead, no responses in months on any of the topics or reported issues.
