hi there,
i am using the homey pro since a month and i am very satisfied with the integration of several devices.
as we have existing humidiefiers from levoit (classic 300s and dual 200s) we now want to integrate them in the homey system, which seems not to be as easy.
the humidifiers are now linked to the vesync app, which is not yet part of the homey environment…
is there any experience to do so? please let me know- thank you
