Hi,

Tanks for all the response, I’m new too this so I have some more questions

If you use blinds with 12-volt control that interfaces with 12V triggering outputs from scaler or receivers, you can control a the blind with triggers from a receiver or scaler and when the receiver is switch on the blinds go down and when the receiver is switch off the blinds go up. This option uses a cable with 2 wires.
So where do I find a 12V trigger interface to control blind, like the Stewart uses to control screens.

Because what I can find for roller blinds is 12 volts down/zero/ up circuit, and her you need a cable with 3 wires, here I can use the CC-12 but I most use 2 relays instead of 1, and a trigger output from a receiver would not work, Is this right?
