Question - Combine functions to 1 module

[rsjabbens 1]

Hello,

 

I ordered a new garagedoor and want to control this from my HC2. The garagedoor can be triggered with a single pulse button. Can i use a 2x 1.5 kW relay switch (FGS222) to connect parallel with a pulse button? So that i can send a pulse from the module? 

 

Another thing i want to do is to connect a pressure mat to my HC2. I want to be able to know if my motorcylce is present or not to allow the garagedoor to automaticly open when i am arriving home (thanks to autofrank for the suggestion, see

forum thread). So i know i can allow a normally open/normaly close input to the binary sensor. 

 

Can i somehow combine those 2 functions with a FSG222 or with the binary sensor?

 

Regards,

Roland

To clarify, i want to achieve:

 

- Allowing the output to a potential free contact from my garage door, to be able to control the garage door from the HC2;

- Allowing the input from a potential free contact from a pressure mat, to know that if it is closed, my motorcycle is present in the garage.

 

 

Do i need one of the Fibaro FGS222 2x 1.5 kW relay switch? Potential free input is possible, but is it possible to use this device as a potential free output? 

Do i need one of the Fibaro Binary Sensor? Is it possible to use this device as a potential free input and output? Input should work, but output?

Do i need them both?

 

I found some article that uses a Fibaro door sensor for input from a pressure mat, this is also an option, but it is nice when i can combine some function to one module. You can find some info

 in an article.

 

What should i use for this, and what parameters need to be modified?

Anyone?

I don't have such a pressure mat, but I am probably right as I say that it is important to connect it to a voltage < 50 V for safety reasons. The input of the relay modules is connected to 230 V, so that leaves you with the D/W sensor or the UBS. The Universal Binary Sensor, as its name implies, is a sensor, the outputs cannot be controlled. For the pulsing of garage door, you'll have to add a relay.

Can it be done with one module? Maybe, but I can't test this for you... It may not work at all. You'll have to experiment and accept possible failure. If the door opener is potential free (floating) then you could try an RGBW. For the mat, using one of the inputs seems quite possible. There is a pull-up resistor (to 11-12 V) so connecting the mat between GND and IN probably works. But I am not so sure about the output. Because it is a PWM LED driver, and not a (potential free) relay, the output can only pull the input of the door opener to ground. Of course, you could add a small signal relay, but then you are sort of violating the "one module" prerequisite.

Does this answer your questions?

You can control your garage door with the double relay. I have it working here too.

The switch is potential free, it has an input and that is switched to the 2 outputs.

I control my 2 garage door with one double relay switch.

 

And I've used 2 binary sensors with 4 switches so I can see in a virtual device if the doors are opened, closed or partially opened.

a universal binary sensor + a 12 V power supply should work......

Thanks for confirming that UBS + (double) Relay works for you.

Maybe I have caused some confusion around the meaning of the word "switch" in the context of a relay module. I have to clarify, because it could lead to dangerous situations.

When I said "Switch" I meant S1 and S2. See for example the schematics in the manual of the FGS-222 Fibaro Double Relay switch. These inputs ("input" may be less ambiguous than "switch" in this context) are NOT potential free and must only by connected to isolated switches, rated for 230 V. They must not be connected to circuits < 50V. If you look at the schematic, one side of the switch connects to "Live". Even if you swap L and N that would not be all-right, one should never confuse Neutral and Protective Earth although they may seem very similar "voltage-wise". Simple rule: L and N *must not* be connected to circuits that were designed to be operated below 50 volt.

The outputs of the relay, meaning IN, Q1 and Q2 are floating (potential free).

So in the end, I think we are saying the same thing, correct?

[TRicky 84]

I couldn't agree more!

 

I only used IN, Q1 and Q2.

S1 and S2 are unused.The original switches of the garagedoor motors are being used and

the Fibaro relays are parallel to them. Just check the common of both 'original' switches because

they will be put together on the IN on the FGS-222.

You wouldn't risk to blow one of the motors or electronics

Thank you guys for the replies with information. Today the garage door is installed (actually they are still working here). Now it is time to start this project and go further with this

I have an one button version that is potential free. When closed, one press is opening the door, another press pauses the door and the press after this is closing the door again. When closing it is working the opposite way. I should also be able to have a separate up/down option on the garage door motor, so maybe i can use this instead, but note sure if this is better.

 

I do not want to use the S1 and S2 i guess, i will do the same as TRicky is describing and use the Fibaro relays parallel. So i feed the relay switch with 230V at L and a Neutral at N. Then i need to connect Q1 and IN parallel over my existing potiontial free button or use Q1 for the up button and Q2 for the down button. I do not connect the L to IN as shown in the manual, because i do not want 230V over my potential free Q1 / Q2

/emoticons/default_icon_wink.gif" alt=";-)" /> I assume this should be correct.

 

TRicky, How do you manage this: And I've used 2 binary sensors with 4 switches so I can see in a virtual device if the doors are opened, closed or partially opened. What sensors did you connect and how is this setup?

 

Thanks for the link to the pressure mat, i think that i will use this in future.
