The only functionality that "exposes" in HomeKit is the open-close of the main contact (Q). Nothing, nothing, nothing else! The additional contacts of the device (S1, S2) to which a switch or a button can be connected for manual control of the installation, or for extra scenarios, are not even exposed in HomeKit as switches / sensors / anything, so creating automations is from torture to impossible. The company's application, on the other hand, has been abandoned for years, and it does not have ANY integrated capability (e.g. a timer, a schedule, something) ... it has nothing! So HomeKit capabilities ... 0. Capabilities without HomeKit (on its own) ... 0.
