Close all blinds with C-touch B&W mk2

Easy... to fully close.. just set the group address to OFF, and to fully open, set it to ON.

You can do all of them at once in a scene.

The shutter relay GUI is a little misleading... the check box that enables "Level Translation" mode shows the alternative is "Proportional Mode"... implying that the proportional operation is not active in Level Translation mode... in actual fact teh shutter relay always has proportional mode active... it's just the "Level Translation" mode that you can turn on or off. The GUI is being updated to clarify this.

You should not need to do any of that clever dickery with logic.

The shutter relay is your friend for this.

 

As ashleigh said... there's no need to do anything fancy like that.

Those special values in the shutter relay are just that.... special cases that allow you to do the magic one/two/three button control from a normal key unit.

The shutter relay still responds to normal lighting commands.. for example if you tell it to go to a level of 75%...

- if it's currently fully open, it will activate the "close" contact for 25% of the failsafe time
- if it's currently fully closed, it will activate the "open" contact for 75% of the failsafe time
- if it's currently at 10%, it will activate the "open" contact for 65% of the failsafe time

This does rely on you setting the failsafe time as close as possible to the actual time it takes the blind to traverse from fully open to fully closed.

In your case, to have a single button on the CTouch that's "all open" or "all closed"... you would set it as an on/off key, and create a scene with all the blind groups in it... this will turn all the groups in the scene on or off.

Note that you can't do this with a single button on a key unit as scene keys on key units don't presently toggle scenes on or off (you could use a scene key and a scene toggle key, but then you have 2 keys so you might as well just make them on and off scenes).

Each room... => Use groups

Roof vents => more groups

Then for the different levels of overall control, use scenes living in a touchscreen. Remote trigger those scenes from key units where you need to.

Then make bigger scenes (scenes of scenes) to do things like open all blinds, open all vents, close all blinds, close all vents.

And then anopther super-scene (of scenes of scenes) to do things like "close everything" and "open bllinds but not vents" and so on.

in other words - build it up out of liddle bits.

 

Another thing to be aware of...

If your shutter relays are on a different network to the key units which are controlling the shutter relay group addresses... the indicators on the key units will not update correctly..

The shutter control key functions on the key units will normally have the indicator ON if the blind is at any position other than fully closed.

This does however rely on the indicator being "corrected" on the key unit by the regular status update on C-Bus.

For example... the "Shutter Toggle" key function just sets the group level to 98% with every press, which would normally leave the indicator ON... when the shutter relay in "Level Translation" mode interprets this as "Close", it starts reporting its position as 0% in the status report, and the key unit updates itself (and hence its indicator) to OFF, and everyone is happy.

Status updates don't go across network bridges though, so this process falls over if the key unit and shutter relay are on different networks. The control of the blinds will still work just fine, it's just the indicators will not always indicate the correct state.

If this concerns you... you will either have to put them all on the same network, or set the indicators to always on or always off.
