Black Friday Update: Please review our FAQs before contacting support!
No, the Shelly Plus 2PM, Shelly Pro 2PM, and Shelly Pro Dual Cover do not natively support adjusting the opening angle of Venetian blinds. These devices can control the up-and-down movement of the blinds, but they do not have the built-in functionality to fine-tune the angle of the slats.
However, with advanced scripting, it may be possible to achieve this functionality through alternative methods.
