Dimmer programming issue

Hey all !

Im new to the Velbus system so i’m in the process of learning.
Bumped into my first “issue”, im 100% sure there is a workaround but i have not ventured out far enough.

The following :
Living room has 2 rows of 3 LED spots(Connected to a dimmer) and 1 row of 3 LED spots (connected to a relay)

All on Switch relay on, Dimmer on = EASY (Toggle)
All off Switch relay off, Dimmer off = EASY (Toggle)
Here we go off track.

Got a button witch Switches off the relay, Atmospheric dim value’s to 50% = EASY
This is where i am stuck.

At first i had the issues the relay and the dimmer would get out of SYNC because of using toggle.
Fix this with keeping toggle on the relay, but follow on the dimmer. So far so good.

Now the issue, the misses wants the “TV mode” Button to be able to switch off Relay, go to 50% BUT the single touch to also just switch them off.
In short

Button 1 = TV mode = 50% on the dimmer single touch
Button 1 = TV mode = Dimmer off single touch.

So like a “toggle” but between 0 and 50% dim values.
Can that be done ? Or is the only toggle possible between 0 and 100% on a dimmer

Looking froward !

Hello and welcome :slight_smile: ,
You can do a 0%-50% toggle on a dimmer using the “multi step dimmer” action (0215).

In the config of the dimmer, you can then set the multi-step values to a “list” of only 2 presets, 0% and 50%.

Heya, Played around with it. This seems perfect. Only downside is

Lets say 4 zones are switched on.
I make a button switch off zone 1 2 3 and zone 4 wich is the dimmer zone i use the multi step dimmer

So

Zone 1 : Off
Zone 2: Off
Zone 3: Off
Zone 4 : Multi step dimmer (https://i.imgur.com/8Ynx2aZ.png)

This is okay, but the initial push will always switch the dimmer to the 0% as the first step. But i would like it to go to 25% like it is configured.
How can i prevent this ?

Multistep will only work as a toggle if it has only 2 steps (as in my screenshot above). You have a lot more steps and the dimmer will simply go to the next in the list, that won’t act as a toggle function.

Yep, you are right, however with only 2 steps i have the same behavior.
Lets say, i use the button TV, i switch off the leds(backline) and we go to 50%(front line dimmer), TV mode, Great !
Afterwards we use the button Living on; switches on the LED(backline) and brings the dimmer up to 100%.(frontline)

Next time we use the TV button again it will turn off all lights as expected, but it will bring the dimmer to 0%. Wich in a way is completely normal as it is the next step.
How can i prevent this behavior ?

The easy way is two separate buttons, one “on”, the other “off”. Or the same button in dual mode (short press “on”, long press “off”. Then you don’t even need multistep, just the actions “on” for the relays and “Atmospheric dimvalue 50%” (214) for the dimmer.

The somewhat more complicated way is “sensing” in which state the outputs are, and accordingly carry out the right action. See below for the general principle.

Or you need to consider off loading all this logic to another platform.
Like ;

Then you could use the state of other devices to determine the scenes to set.

I think what you’re learning towards is Automation with Logic, rather than mere Control.
