Shutter Relay Misbehaving?

Recently I installed 2 shutter relays to replace 1 cross-over relay in an installation that included many cross-over relays. Where a scene that included cross-over relays and shutter groups is used to say, open or close all blinds, the shutter relay controlled blinds will move in unison with other blinds but will reverse direction after about 10 secs at the end of travel. The scene is pulsed on for 40 secs and the fail-safe shutter time is the same. The app log does not show any reversals. Any ideas?

What command are you using for the shutter relay? Just open and close (i.e. 0 and 255), or the toggle functions?

If you are using open and close and you pulse the ga, it will to to 255 to open the blinds, then after 40 seconds revert to 0 which will close the blind again.

 

Thanks Ashley I'll set up a separate ga for the shutter relay in the scene that avoids the 40s on pulse for the cross-over ga.
