Synchronize brightness level dimmers?

Jacob Wiqvist shared this question 8 years ago
Need Answer

Does anybody know how you accomplish synchronized brightens witch different z-wave dimmers?


I can accomplish this buy a rule and group of lights, but then the brightness is not sent at the same time?

But according to the Fibaro manual it should be possible in another way? But is it possible with to different brands?

With Philips Hue it is possible to have perfect sync between lights with out seeing any diference in light intensity and and speed!


Is this possible with z-wave?

With hue it is done through the app only isn't it? Thus just create a virtual level control as your switch and control all the modules (lights) through that virtual switch. With a physical switch it is more difficult, as you are using one module to control others via the Zipabox. You could insert two dimmer modules into the switch, one connected to the switch, the other independently connected to the lighting circuit. That way when you physically adjust the switch, it sends the signal to the Zipabox, that in turn sends the signal to all dimmer modules you associate with it. I know not ideal.

Yes Fibaro modules can has associated devices which would work the way you want, but I do not think the Zipabox supports this feature. Maybe Zipato Support can confirm this, and show us how to do it. It would be very good to have.


Rules.


Maybe try binding the dimmer module to the other module, will have to be done in the old ui. Again not sure if this will work. I will look into it over the weekend. You may have to change the Parameter 21 as stated in the above picture to 1.

In professionell installations with DALI there is super simple to sync lighets dimmer state. If you just press and hold the the switch for 10 seconds, al the lights connected to the same switch will sync its light levels and you can dim them synchronized. But all the dali lights have its own dimmer actuator in them. So potentialy al lights in a room could have different levels, like philips hue.


Very strange that this is so hard with Z-wav. And that you don't can make rules that dim the lights between a certain time to create a smooth dimming in a home cinema setup. You can setup on Fibaro dimmers, start change up or down but it is not beautiful with very obvious steps and not possible to set ups the time.


It is very complex with Z-wave to control the time you want lights to go from 0-100% or the opposite. You can set a value in the dimmer settings but that is often very short. 0 to 2,5 second.


Maybe you want half a minute to dim when movie time is ahed. And you want 1024 instead of 99 steps, not visible steps, like now.


And yes I know how to make a rule with time between steps. Is this even possible with z-wave? Maybe ask Fibaro about firmware update?

It looks like the Qubino Flush dimmers can associate with multilevel even when set by controller. At least it's what I interpret from the manual:


Associated Groups:

Group 1: multilevel (triggered at changes of state/value of the Flush

dimmer)

Group 2: basic on/off (triggered at change of the input I2 state and

reflecting its state)

Group 3: basic on/off (triggered at change of the input I3 state and

reflecting its state)

Group 4: default reporting group (reserved for the main controller).


I checked the Fibaro Dimmer 2 as well but it will only associate from it's switch inputs S1 and S2.


A good thing I checked as I was about to buy a bunch of Fibaro Dimmers where I need to sync three of them.

But is it really sync? Mening that the same light level is instantly synced and not like with a rule, first you set the dimmer and then the other dimmer state is updated. Like my rule in the first post?!???


More like continues sync during dimming!

This would be great. i agree Jacob this is something that needs to be done better. i was hoping binding would work, but alas it does not.


If you change the dimming step time for the module, isn't that enough time for the other module to change and be roughly in sync. 2.5 seconds should be enough.

I have sent a mail to Qubino to clarify. The way I read that sentence in the manual it should set all other associated dimmers to same level. And association should be fairly quick. If this is possible then you would only need to control the "master" dimmer. I can see some nasty circular references here so only one should be master.

Heh, I just checked to see how many nodes it supports on assoc and there are obviously multiple manuals: "Group 2: multilevel (triggered at changes of state/value

of the Flush dimmer) up to 16 nodes". 16 nodes should cover most needs :)

Qubino says the dimmers will sync when associated even when it is controlled from the controller and not only button.


This will probably be my solution where I have 3 downlight zones in my kitchen. I will only wire up 1 dimmer with button and let it control the others.

But sync is one thing? But instantly synced is another? Will they sync continuously or after the master have set its new value? That is what I am interested in? Otherwise as I have bin saying you could use a rule.


And how do I set up this sync? I have two Qubino dimmers!
