Doorbell with Fibaro Universal Sensor

[Guest Sander]

Hello,

I bought the Fibaro Universal sensor to create a trigger when the doorbell is bushed. As a energy source I use a 9v battery. And I connected the doorbell wire to IN 1.

However it does not work.

Can someone please help me?

Ragards,

@Sander, the doorbell has two connections on its switch. You connected one side to IN1, can you confirm that you connected the other side to GND/0V?

Hi all,

I used the universal sensor to make a doorbell (including a temp. sensor). I used a 9v battery but it's empty after 3 days, is that normal?

Anybody?

I guess.. what we don't know, is the current consumption of the Universal Sensor. I looked at the

for the sensor and there's no detail.

However, the capacity rating of an Energizer 9V PP3 battery is 625mah. Assuming 5ma current consumption (I have no clue), and using the

, it comes up with 4 days. If nothing else, it gives you an order of magnitude and expectation.

I use 12V 500ma power (240V) adapters with my sensors.

I think the problem is, fibaro universal sensor is always awake! It means it does not go to sleep like other battery operated devices.

This is why the battery do not last very long.

Most old doorbell systems use 6 volts (ac). Try if you can use that to power the universal sensor. maybe with a small dc dc (buck) boost converter to boost the voltage.

because indeed the universal sensor uses way to much power and that's probably why they designed the new door sensor.

Thanks for your replies, I just wanted to be sure that the sensor is not going to work on a battery.

Gives me a good reason to try to implement an EnOcean battery-less solution

deraaij,

Universal sensor is not batery operated device.

It is always awake so it can route zwave frames.

If You need batery operated sensor You can use our new door/window sensor. It also has 1 binary input to use it in solutions as You need.

It is smalles batery operated door sensor right now.

@Sander, did you eventually managed to get this work or can somebody help me with this?

I have a 'normal' doorbell: pushbutton, power converter and chime, with the pushbutton connected between the converter and the chime.

I connected one side of the pushbutton to GND and the other side to IN2. On the output of the universal sensor I connected OUT2 between the power converter and the chime. The fibaro manual shows the output as a normal relay switch, so this should work.

However, when I push the button, the sensor is breached but the chime is not ringing.

does anybody know what is wrong?

[Guest Lode]

Gilbert,

You don't need to use the output of the universal sensor here

Connect IN2 with one wire of your doorbell (doesn't matter wich of the two wires)

Connect + of your powerconverter with red wire from universal sensor.

Connect GND from universal sensor with - of your powerconverter and second wire of your doorbell.

This should work.....

Thanks for your reply Lode.

I tried this but then the sensor is always breached. I think the problem is the universal sensor has a power supply other then the doorbell (IN1 is in use for another purpose). I'm going to add an external relay. I think that should work.

[Guest Lode]

Gilbert ,

Did you set parameter 4 to normally opened ?

[gilbert 0]

Yes I did. With only the push button connected it does work.

can i power my universal sensor with 12.8 AC ??

[sonnyboy 11]

No you cant. You must have DC.

do not know if this will help? but i think dc only not sure if relays etc help?

I connected my doorbel the same as the link described from robbshop.nl but then without the relais because 150ma is quite a lot. But I had to include a diode between the chime and the module because otherwise it didn't work. I have one of those coil and magnet chime. It didn't hold the bel when holding the doorbel button but released it directly. Including a diode fixed that! Now it runs like a chime!

Hi Forum,

 

I'm looking for some help with wiring my doorbell. I have no clue why it will not work. Enclosed I forward the wiring scheme. The strange thing is, the wiring works while holding the input wire manually with the grd-connection from the sensor. But if I connect the wires from my pushbutton with the wires the chime stops belling and the output was just a low level vibration from the chime. The wires to the doorbell are simple as it could be, one wire out to pushbutton and one wire back. Did somebody have an idea whats the matter?

 

Best Michael
