Window shutters

any recommendation for a window shutters adapter?
I’m looking for a system with din holder to place in the Electrical cabinet and work as a central system for 12 shutters

Have you looked at the Shelly range? They have both small embedded units and DIN rail “pro” units. Good binding for OpenHAB, can work with dry contacts to switch whatever voltage your blinds use plus webhooks and MQTT all built in.
