What is the best shutter module that works out of the box with SmartThings and supports all functionalities (open, close, and set percentage)? (It doesn’t matter what protocol it uses e.g. zigbee, z-wave or WiFi)
What country are you in? The device selection does vary by region.
Also, do you already have a smartthings/Aeotec hub?
I have 220v electricity and yes I do have Aeotec hub. Honestly after testing multuple ones. I found NodOn (Zigbee) and Shelly 2.5 (Wi-Fi) are the best options but maybe you have something else to share
