How to limit a roller shutter 3 based on his position

[SirRekt 0]

Hi there,

I got a roller shutter 3 which controls via two contactors a 12VDC motor. I calibrate it by time of UP and DOWN movement but when it gets DOWN and i press again the DOWN button trigger, it makes another cycle down, the same happening when getting it up.

There is any way, maybe by lua script (which i'm not an expert in) to tell the roller shutter 3 that if it's in DOWN position it should go ONLY UP and if it's in UP position it should go ONLY DOWN?

Thank you so much!

You can even do this in block scenes if you want. Here's some hints:

1. Create a global variable "RollerStatus". A value of 0 means roller closed, 1 means open.

2. Create a block scene to open the roller, but only if RollerStatus =0. Also then set RollerStatus back to 1.

3. Create a block scene to close the roller, but only if RollerStatus = 1. Also set roller status back to 0.

4. Assign the scenes to your button triggers

 

Then you can add some extra conditions/functionality to deal with edge cases like what to do if either button is clicked before movement completed, etc

 

Have fun ?

Hi, 

Thanks for the reply. 

Even doing what you said, it doesn't work. I also created two separate scenes, one for (if closing then set rollerstatus to 0) and the other one (if opening then set rollerstatus to 1) but I saw that no matter if I close or open the roller, both scenes are triggered. May that be because it is calibrated by time movement and not by automatic calibration?

Thank you so much!

You want to avoid a changing of the global variable immediately triggering the other scene. I think you should only need a single scene per direction:

 

IF

RollerStatus=0

THEN

RollerStatus=1

AND

Roller Shutter = open 0s

Roller Shutter = stop 10s (Ie stop the shutter after a few seconds when it is in the right position)
