Sinlge Relay Switch with Push-Buttons

[rog 2]

Hi All,

I was fighting with the following setup: I have four push-buttons in the wall and a classical relay in the basement switching the light on and off. I now added a Fibaro Single Relay Switch immediately in front of the relay in the basement.

Technically it works fairly well but I am still fighting with the parameters. Currently my setup is:

• Parameter 4 (Auto-Off) is set to 1s;
• Parameter 13 (State Change (ON / OFF) for toggle switch) is set to "ON = switch contacts connected / OFF = switch contacts disconnected";
• Parameter 14 (Switch Type - momentary or toggle. Default Setting: momentary) is set to Momentary Switch

Rest is default. Basically everything works. I can press the wall button and the light changes state, I can click on the button in HC2 and the light changes state. The only thing which does not work is that HC2 does not have a clue in which state the light is. E.g. if the light is off and I press a wall-button, the light goes obviously on but HC2 still thinks it is off. When I then click on the "button" in HC2, light switches off but HC2 now thinks that it is on.

 

What do I need to do?

 

Wiring is: N is Neutral, I and LN are Power, O goes to the "old" relay in the basement and S1 is connected to the wire coming from the push-buttons in the wall.

 

Thanks

Roger

I do not really get your setup, if you are using relay in auto-off mode, it will go off every time after 1s, so it will never reflect state of light. In addition, what switch do you have? Mentioned settings apply to both momentary and toggle switches.

Hi,

I now played around with it and changed the cabling. I have four momentary switches in parallel in front of my relay. Technically this works fine with one exception. The state in HC2 does not reflect the changes initiated by the momentary switches.

Let's say I switch on the light on HC2 and then switch it off by using a momentary switch. The light goes off but HC2 does still show on. If I take HC2 then to switch it off - it remains switched off (as expected) but I cannot see the current state of the light.

I guess it is a configuration problem but I was unable to figure that one out

I guess you are using switches connected ordinary to S1 or S2 connectors? If so it should not be matter of configuration. Check if node number 1 (Home Center) is assigned to 3rd association group.

thank you for your answer. The switches are connected to S1.

And it is kind of magic: No, device 1 was not in the association groups. I added it, saved it but it did not stick and all of a sudden, it is there.

I have no clue why but it works

Thank you

Roger
