Fibaro Heat Controller 0 degrees sensor

[eureka 9]

Hi,

 

Just installed my Fibaro Heat Controller with Sensor. My homecenter 2 is picking up both the sensor and the heat controller (also connection between radiator and sensor was executed), so far so good. However, if I look at the temperature that the seperate sensor is providing. It says it's 0 degrees celsius. I've been waiting for a while now and also did a soft reset but it's still at 0 degrees.

 

What can be going wrong? or is this a known bug?

 

also: is there a known way to fix the sensor to the wall? I want it to be at 1.50meters to get correct temperature. But if i would fix it using tape I cannot get to the battery anymore. Probably i'm missing something because i can't imagine that they make a seperate sensor without having a way to fix it to something... right?

Well, that's not my experience with FW 4.4, I'm sorry to say.

I am sorry about that, maybe I should not have said that.

 

We can try to find out why our results differ. I have limited time right now but I'll try a few things anyway:

 

No 2 systems are equal. And I have *very* limited data, so I try not to jump to conclusions when I observe my FGTs... For example, it's not cold here in Belgium, the sun has come out a little bit -> TRVs stay closed. That is better than 4.3 but hardly unexpected!

 

Room temperature is 22 °C and TRV set to 21 so no surprise there. When I set it to 24 °C about 10 seconds the motor spins and the valve opens. The water temperature is 33° and my panel is heating... If I set the FGT back to 21 °C, motor spins, valve closes.

 

But that is no exactly what you are doing, I understand the sequence of events is different... To repeat your experiment(s), unfortunately, I have to use your boiler control scripts and I am not controlling my heating system in that way.

 

So I prove nothing...

First the (well connected thru BLE ) separate sensor doesn't move at all mostly. While other temperature sensors (Netatmo, Everspring...) are going up in a paralell way the connected Fibaro sensor does not move up or only after a few hours...

 

It does not update very often when you look at the event log. Maybe a bit more data points if you look at the "Consumption" tab though.

 

In my room, it tracks a nearby sensor to +/- 0.5 degrees though (but add the accuracy of the sensors, please)! 

Can you have a look at graphs under "Consumption" tab to confirm what you see?

If that kind of tracking does not meet your expectations than I have really bad news for you: although the BLE probe reports every 10 minutes, the FGT doesn't do that, and there are no configuration options! Don't shoot the messenger, please.

 

I'm not sure if the "Eurotronic Spirit" with external probe would make you happier. That's the only TRV with an external probe that I know of... It uses another Z-Wave sensor as a probe, but there are some specific requirements. I've read the manual, but I do not own such a device, I cannot tell you much more.

 

I think, what you want is a "mains powered actuator" for your valves - they exist, but not in Z-Wave. I'm certain some users have them or planned to use them. But then you need a bunch of relays + your own code... If I wanted the ultimate control, that is what I would try...

 

I cannot tell you much more. I do not sell these FGTs, I am an end-user. But I hate to see other people struggle with this device. We have had a long PM about these valves and I think the FGT cannot do what you want and you will not be a happy customer. It does not matter how hard I try.

 

The only thing I can do, is post a picture of how well my FGT sensor tracks my "SOFA" sensor...

Hello there!

 

Any news from the experts with these cold days? Is the 4.4 version working well?

I am not sure if you are talking to me... But if you are, then "Thank you for the compliment".

 

I have limited data but I am 95% certain that it is better than 4.3.

 

On the other hand, you can bet Fibaro is already working on 4.5 so if you do not have a Home Center to update and you are not too unhappy with 4.3 it might be worth waiting on 4.5. Fibaro never discloses ETA so please do not shoot the messenger, I do not know when it will be ready.

 

Also please note:

Not for me. With all kinds of tweaking and all kinds of help (thank you, Peter) I had to conclude that the FGT with firmware 4.4 does not do....anything, execept making some noise sometime, especially on wednesdays which seems to be set as 'calibration' day.

No regulating the room temperature at all with this firmware, temperature setpoint at 21 ° C , you have to manually switch of the FGT before you get coioked at 25 or 26 ° C.

 

So I decided to leave them and bought the the Honeywell Evohome system. It does exactly what I expected and wanted: warm every room at the right temperature at the right time and keeping it at that temperature 'flatline', meaning that once the set temp is reached, you don't even see a 'sawblade' type of graph anymore: the finetuning of the valves by the 'optimisation'-algorythm is very efficient and the system learns when it schould close the valves a bit more or open them up a bit more to keep the temp constant.

 

I still have 6 FGT's laying in a drawer. If the Honeywellsystem (connected to Fibaro by Remco Boer's excellent scene and VD and to IFTTT also) continues to work so flawlessly when it's real winter here, I'll sell them
