The Shelly 2PM Gen4. Its two channels and interlock/cover mode with obstacle detection are built to drive a shutter or blind motor up and down from one module. The Aqara Single Switch Module T1 (No Neutral) is a single-channel switch and cannot control a bi-directional motor on its own.

Only the Aqara Single Switch Module T1 (No Neutral). The Shelly 2PM Gen4 requires a neutral wire at the install point, so it suits homes with standard modern wiring, while the Aqara is the option for older no-neutral boxes.
