RGBW 0-10V input not working

[mvrekum 2]

Hi,

I have a

connected to a RGBW controler. This light sensor has an output of 0-10V. So you should think it would work perfectly with the RGBW controler.

Input 1 is set to 0-10V. If the lightsensor is covered, so completely dark, the output is 0 Volt, not connected to anything. However, once connected to the RGBW controler the output will not drop below 1.8 Volt in complete darkness.

Also input 2 is configured as an nrmal dimmer input. On this input I have a

connected. This has a simple relay as output that shorts the RGBW input to ground. When activated the device screen (its a dimmer input) shows a dim level of 68% (should be 100% since the input is shorted to ground)

Question: is my RGBW device defective or am i doing something wrong? This way the light sensor is absolutely useless. I can live with the rain sensor however.

Btw, I am using these sensors to control my awning. It automaticly goes down when there is enough sunlight and goes up when sunlight goes away or when it starts raining. I still have to add a windsensor.

Neither one. It's a 4-20mA signal and it is a pulse signal. So you have to count the pulses. The higher the pulse frequency the more wind.

Missed this part

Output: Analog Sensor,4-20mA, 0-5v, 0-10v, 5v pulse

Color: black material: stainless steel

signal: pulse signal, current signal, voltage signal

Ah, your holding back information. But even now that you have several output signals, you still can not tell if the 0-10V is passive or active.

Like I wrote in a previous post look in the manual or ask the supplier before you buy.

I'm curious where you found this info. I found this page:

but it only mentions the pulsed signal.

I received the wind speed sensor and direction sensor in a 0-10v version today.

I have received 5 of them. Will connect the sensor tomorrow and post the results.

Any NL interesten let me know.....

Works great. Had a good day testing with strong wind and compared it with a local Weather Station.

Hi first post for me:

I am trying to add a sensor to my RGBW unit.

I just don't understand how I can feed the sensor 5V when the main controller PSU is 24V.

The sensor input is a single wire, how can I compleat the circuit. Fibaro aftersales are not very helpfull at the moment.

I am also wondering the same for adding a potentiometer to dim the lights.

Can you post link to documentation of this sensor?

The RGBW module requires a low impedance output to be able to set a 0v on the RGBW 0-10v input.

Take an ampermeter between the GND and input1 of the RGBW module (input1 configured as 0-10v input), you'll see that it requires 60mA of sink current !!! That's really high sink current. Meaning that there's some kind of low impedance pull-up in the input circuit.

For my SBS project (

), I had to use 80mA capable buffer output to be able to reach 0v ...

But that is not the only issue of this module. In order to limit the ZWAVE network traffic, the RGBW module only transmit the measured value every 100mV, meaning that you have only 100 different values available ...

But it is still a great module !

thank you for the reply. internet has been down for a couple of days.

the sensor is a sharp GP2Y0A41SK0F

the data manual of the sensor is here:

Nicolai this sensor is active and has output between 0 and Vcc. You can read a little more about active and passive sensors

@mvrekum

Can you give me some reference for your rain gauge? I'm looking to install this kind of measurement but can't find any device in 0-10V output voltage...

Thanks for your help.

That seems very odd. The obvious way it should work is that it would only transmit when the change is 100 mV or more but the available values should still be the full resolution. Say that the current value is 234 mV which has been sent and that the value changes to 428 mV which is a change bigger than 100 mV and you will get the new value with the actual value 428 mV. Are you sure it works the way you say? That would be extremely strange...

Again puzzeling with the RGBW module. Have attached a Servodan Lux sensor 43-198 . The one which Fibaro suggests on their marketing website.

I have set the sensor measuring 300-30000 lux. So 300 is 0v and 30.000 is 10v. Yesterday evening the measurment did not drop 2400 lux (0,5v) while it was dark so it should give a measurment of 300lux (0v) as of the settings of my sensor.

Have the same problem with my windsensor. With no wind, wich is 0v it still gives a value 2,1 m/s.

Measurment and updates between 0-1v are not correct. All above 1v are fine so sensors are stil partly usable.

Why doesn't it drop to 300lux being 0v?

[j.nowacki 5]

Dino, did you measured the output of that sensor with multimeter?

[Dino 0]

No, will do this evening.

But Fibaro advises this sensor so what is your experience ?

Fibaro , is my problem related to the above? Again spend 120 euro's on 2x sensors which you advise on your website and spend again many hours solving and again it does not opporate as it should. Please......

Dino, did you measured the output of that sensor with multimeter?

Yes, did that an i measure in complete darkness 0,245 v. According to my expecttaions it should be 0v. How is that possible. Fibaro suggests this sensor?

j.nowacki,

thank you for the information.

Understanding exsactly what kind of sensors will wordk with the unit is becoming very dificult.

the sensor input on the unit looks like a single ground connection (-, sinkconnection, pasive input). The sensor I have bought has three wires and is an active senor meaning that it will supply the unit input with current.

What I do not understand is how I can stay within the 0-10V if the led controller is driven by a 24V psu. Will I need to convert the 24V from the PSU to 10V to also power the sensor?

p.s. I will also be using potentiometers, and the 24V psu will also be an issue here.

[understanding exsactly what kind of sensors will wordk with the unit is becoming very dificult.

Indeed it is very hard. Even de sensors which are suggested on de Fibaro website have issues.

Fibaro, any news on my questions?

can anyone help me out please? is there a skype number I can call?
