Hi Arnold, welcome.
Posting questions “in the wild” to a certain developer often ends up nowhere.
Please send your questions by email to the developer, the preferred way to contact that person, see app page at homey app store.
However, there appears to be a dedicated app topic as well:

.
NB
The “Developers” category is meant for, um, app developers
