Guess this is part of a larger issue I am having.
See: Homey app stops working correctly after moving Homey to IoT VLAN
Will keep you updated here.
*** UPDATE*** : I figured it out.
I was using my dedicated read-only homey user to setup the Beeclear but apperently that doesn’t work. 
So I used the standard beeclear user to reinstall the whole app+device and later used the app to change the user back to the readonly Homey user.
@Gruijter : All running ok again!
