I have a motorised blind and i am using two channels on the relay. One for up and one for down. I am using a scene for the interlock between up and down channels and using a pluse timer for the delay between button pushes and a 4 s ramp rate. But i want to have a timer setup on a seperate button on the touch screen to operate for about 7 Secs to drive the blind to half way. Is this possible without using a pac or any other devices that have a logic engine to acheive this. Am i missing something or is it just not possible.
