Thanks for the detailed investigation — that was exactly the right lead! You’re correct that windowcoverings_closed is the key capability Homey needs to show the Quick Action toggle.
I’ve added it to the Curtain Motor driver in v1.0.91 (just published TEST Tuya Local | Homey). The toggle sends open/close commands and its state reflects the actual position — closed = 0%, open = anything above. Existing curtain devices are migrated automatically; just restart the Tuya Local app after updating and the Quick Action should appear.
Note: windowcoverings_opened is not a standard Homey capability — it’s a custom one defined by the Aqara app, so we don’t need it here. windowcoverings_closed alone is sufficient per the Homey developer docs.

Let me know if the Quick Action shows up after the update!
