Hello all,
Fairly new to all this but have decided to dip the big toe.
Background:
Have a HC2 home automation system at home and have a couple of 'Fibaro roller shutter modules' < Most people will kill me for using such a system here but its a long story.
The module is a simply component with 2 relays inside, one for up, one for down with a three wire output (Common, up down) @ 240v. Simply, the relay provides a current for the respective function for the duration specified.
Now I am looking at using the module to control a roller blind motor that acts in a very different way. The motor has 4 low input connections (common, up, down, stop). Simply, a pulse is all that is required to start a 'movement' up/common or down/common with a pulse to the stop/common to stop.
Now the motor can handle a continuous signal to go up/down and hence using a couple of icecube relays can start the up/down movement. The problem is sending the stop pulse to stop the motor.
I have used a couple of icecube relays to make a circuit that is either open/closed during the sending of an up/down movement and with the opposite state when no signal is being sent.
The plan is to use this change of state to send a pulse to the stop/common...
Now I was thinking of using a 555 timer OR capacitor OR arduino uno.
The problem in its simpliest form though is that I need a relay to activate temporarily sending a stop signal after the fibaro module has finished sending the up or down signal...
Any advise would be greatly appreciated though please don't say get rid of the fibaro... I am not the most advanced and it is easy to use for other things.
