how to connect fibaro dimmer when there is 2 switches?

i have a fibaro dimmer switch (Universal Dimmer 500W Insert Module), and I saw there is two way to connect it

  1. using 2 wires
  2. using 3 wires
    but what if the switch has another swich that can turn the light on\off also?
    the scenario is this: on my mom room there is a switch on the wall that can turn on\off the room light, but she also has a switch near her bed to turn on\off the room light
    is it possible to connect the fibaro dimmer switch to the wall and also make her switch near the bed to work also by itself?

i need some explanation
Thanks

It sounds like you want a 3-way configuration.

thank you, but i find out now on the room that every switch has 3 wires. and the sketch shows two wire connection
is there a way to connect 2 switches that each one has 3 wires?

From the description that you have provided, I have no clue what switches you have or how they are actually wired. I can only encourage you to get an electrician to do this for you.

in israel no one heard about zwave and fibaro products. anyhow the scenario is this:
every switch has 3 wires (the first cable is going to the light, the second cable is the phase, and the third cable is going to the second swich) like shown in the image blow:

The electrician doesn’t really need to understand Z-Wave, they simply need to understand the wiring diagram and what is in the wall.

Perhaps these Vesternet guides will help you.

2-Way Lighting Using Fibaro Dimmer Modules
Vesternet refers to this as 2-way. But this is known as 3-way in the U.S. Two switches plus one load equals 3-way. We haven’t switches to metric wiring yet.

i tried the same chart but the problem that just the right switch is working and the left switch doesnot work,
say like when i turn the light on with the right switch, i can’t turn off the light with the left switch

Did you set configuration variable 17 to 1?

how do i set this?

Open the device Device Options tab. Click Add configuration settings to add a new line. On the new line, change Variable to 17 and select Data Size as 1 byte dec. Enter 1 in Desired Value. Now close the device block, click Save and, when the reload has finished, refresh your browser page. If you check the Device Options tab, you should see the Current Value for variable 17 is now 1.

sorry, but i don’t have the home center 2, i use veralite

These are instructions for the Vera!

wow!! it worked!!! wow im so happy i almost gave up with this, thank you RexBeckett!!
i have no clue what this configuration did to the dimmer, can i have a small understanding please?

also something i couldn’t figure out is sometimes the light turn off completely, and sometimes there is very small light
like shown in the picture attached, im using regular on off switch

Configuration variable 17 controls the special mode that allows two-way switching with bi-stable switches. All the configuration variables are explained in the product instructions - although not always very clearly.
also something i couldn't figure out is sometimes the light turn off completely, and sometimes there is very small light like shown in the picture attached, im using regular on off switch
With this type of switching and an incandescent lamp, off should be off. Is it possible that you are setting a low dim level from Vera so what you are seeing is a low on rather than an off?

maby, it happens when i mix double taps fast from the right switch and then from the second switch i just tap once (something like that not really sure), i think maby it goes to dimming mode or something, but now when i look at the manual at config #14 it says:
switch type - choose between momentary switch and toggle switch (default is 0)
0 momentary switch
1 toggle switch
2 roller blind
but in vera i need to choose monitor in order to type a desire value, which number should i choose? and what is dec & hex?

there is also configuration 15 that says that double click is setting the light to 100% and it is default

Yes you should set configuration variable 14 to 1 to suit your bi-stable switches. Follow the same procedure as for variable 17.

When you add a variable to the list, you have a choice of Data Size. The default monitor only just displays the current value of the variable. To change a variable you need to set Data Size to one of the n byte options. The options define the size of the variable and the type of number (decimal or hexadecimal) you will enter. Most variables are one byte and you would normally enter the value as decimal.

[ul][li]1 bye dec 0-255 (use for most variables)[/li]
[li]1 bye hex 0-FF[/li]
[li]2 bye dec 0-65535 (required for variables with large ranges)[/li]
[li]2 bye hex 0-FFFF[/li]
[li]etc.[/li][/ul]
