Tips and tricks
Re-register to feedback from the video system
when either the video system or the control system
restarts
When either the video system or the control system restarts, the
control system must re-register to the events that the video system
sends when someone uses the Touch10 in-room controls or pushes
a new in-room control panel to the Touch10.
For terminal output mode:
xfeedback register event/UserInterface/Extensions/Widget
For XML output mode:
xfeedback register event/UserInterface/Extensions/Event
xfeedback register event/UserInterface/Extensions/Widget/
LayoutUpdated
Consult the API for in-room control chapter for more details.
Initialize all widgets
It is important that the control system initializes all the widgets on the
Touch10 in-room control panel in the following situations:
• When the control system connects to the video system for the
first time.
• When the video system restarts.
• When the control system restarts.
• When a new in-room control panel is exported to the video
system (as response to a LayoutUpdated event).
If this is not done, then the Touch10 may show incorrect values and
not truly reflect the status of the room.
Use the
SetValue command to set the initial values.
Always send values back to the video system
when something changes
To avoid unexpected behavior and ambiguities, the control system
must always send
SetValue commands to the video system when
something changes. This applies also when the change is triggered
by someone using the controls on the Touch10.
For example, it makes no difference if you use a slider on the
Touch 10 in-control panel to dim the light, or a physical dimmer in
the room, or another touch panel. The control system must always
send the dimmer value back to the video system using the
SetValue
command.
Update the in-room control panel
When you export a new in-room control panel to the video system,
the old panel is overwritten and replaced by the new one.
a. Launch the in-room control editor from the video system’s
web interface.
b. Create the in-room control panel you want, or import a
previously saved panel from file (Import > From file).
c. Click Export > To codec.
Other useful stuff
Remember previous values when turning lights off (eg a light with a
slider for dimming and toggle for on/off), remember the current light
state when turning off, and use that value when turning back on.
Eg if the light is at 40 %, and the user presses off, she will expect it to
go back to 40 % (not 100%) when pressing pressing the “on” again.
Remember also to set the power switch to off if sliding to 0 %.
For blinds, consider to use the following strategy: hort press on a
direction arrow tilts the blinds. If tilted all the way already, moves the
blinds slightly.
Long press on a direction arrow starts moving the blind that direction,
doesn’t stop until all the way up / down.
