I have the following two buttons in my Velbus installation: “On Holiday” and “Back Home”.
The “On Holiday” button sets the feedback lighting on certain switches to ‘red flashing’ using action code 1702.
There also needs to be a sort of mini simulated presence.
I’m currently testing this with a single lamp at a single time.
In the living room, I have a VMBELO switch with a program that uses the astro clock to switch on an ambient lamp (CH29 → 101 → Relay 13 CH4).
I’ve also assigned two buttons to the “On Holiday” and “Back Home” functions:
CH13 = 901 (Activate astro program)
CH15 = 902 (Deactivate astro program)
The feedback lighting for these buttons is set to “Monitoring”.
This works.
But in my current setup, I cannot see whether the system is in the “On Holiday” or “Back Home” mode. Why not? Because there is no relay on which I can base the feedback.
I want to see the status feedback of the program (active/inactive), not the status of the ambient lamp relay itself.
Specifically:
• When CH13 is pressed, the feedback for CH13 (left) should be on, and CH15 (right) off.
• When CH15 is pressed, the opposite.
Question 1:
How can I best achieve this without using two extra virtual relays? (I’m almost out of them 
).
Why two? Because with action 135, I can only show the feedback for one of the two states.
Question 2:
Is there another or better way to achieve my goal?
Question 3:
I found action codes 1702 and 1705 by chance, but I can’t find them in any public Velbus documentation.
Can someone share the link where the full list of action codes is available?
There might be other interesting codes hidden in the system.
