Which SONOFF roller shutter switches should I buy?
SONOFF's roller shutter switches drive AC curtain and shutter motors up to 1 A, in two modules and two Orb wall switches.
The MINI-RBS and Orb-RBS are Matter over Wi-Fi, and the MINI-ZBRBS and Orb-ZBRBS are Zigbee.
These models support percentage control, scheduled opening and closing, and calibration. The Zigbee models act as Zigbee routers, and the Orb-ZBRBS needs a neutral wire. SONOFF states that the motor should not run in one direction for more than 2 minutes.

The MINI-RBS and MINI-ZBRBS are modules that fit small wall boxes. The Orb-RBS and Orb-ZBRBS put the same function in a finished 86 mm wall switch, and their codes add -E to the module code.[1–4]
