WHY DOES 4.4 STILL NOT WORK AFTER ALMOST A YEAR????

[oajungen 5]

I have 10 HC's installed since december 2018. Have had a very trouble some (scripting the HC to max for 10 mintunes when heating is necessary) winter concerning heating because the HC's don't open / close the valve when needed. Hopefully installed 4.4 a week ago and started heating today….. IT STILL DOESN'T WORK! Valves stay closed until I put the requested temp more than 1.5C above the measured temp with the temp probe.

 

What is happening and why is Fibaro not able to solve this problem.

I want to help with sending log files, but Fibaro please make clear what is going wrong!!!

 

Not using any of the adapters!

 

I want my money back to buy thermostats which does work!

Do you know when the firmware 4.5 will be available ? And do you know what are the improve of them ?

Because finally we find very few opinions, and they are contradictory.

Agreed.

On the Jeedom forum, two users had problems with version 4.4. They say that it is buggy and that it does not work (it does not regulate properly).

I know someone who is active on Jeedom, he is part of the PM group but he has not given me any feedback since 4.4. Possibly, he only got hold recently of a 4.4 version FGT so he may chime in after some time.

Fibaro never announces this... I can only tell you that it exists, but it takes time for them to finalize stuff, like updating the manual, ...

 

Catch-22

 

If a user knows the release date and the features, then he is not allowed to tell you...

And if he does not know, he cannot tell them...

When you say, that external sensor does not work properly, should I remove pairing? Because right now I have 4 TRVs and none of them works. Like, in my office room, where I currently am, there is 25.5 degrees, setpoint is 23 degrees and TRV opened the radiator for twenty minutes or something. In the bedroom, I have 2 TRV, setpoint for 19 degrees, current temperature 22 degrees, and heat controller keeps turning radiators on sometimes. Like WHY??? Even a six-year-old would do a better job regulating it. I get that everybody has a different opinion on a comfortable temperature, but when I say I want 19 degrees, I certainly do not want 22.

 

I have to say I don't use HC2, I have a custom SmartThings controller, but I can verify through touch that the setpoint is correct. If there are some custom HC2 software regulators which use some secret z-wave commands for turning the valve by %, give me that commands and I will develop my own PID regulator. Otherwise, Fibaro, if you are listening, expect a lot of RMA until I get back my money.

I did not say that in this topic...

 

It is important to update your FGT FW to 4.4. The 4.3 is not very good. And 4.0 can crash with external sensor, causing overheating, so that might be your problem. In my house, the 4.0 series definitely crashed and caused overheating. That 4.4 is completely new firmware.

 

 

What is the FW of your FGTs?

Don't shoot the messenger!

 

That is very unfortunate, because:

 

a) you cannot update your FGTs

b) you cannot download "blackbox logs". They helps diagnosing issues... But this feature only exists

 

I recommend, you start by mailing to [email protected] to get help, because that is the official way. This forum is mainly an end-user forum.

No, such hidden command(s) do not exist. You can trust me, I would have found out about it because I know quite a few people who would like to set the % opening of the valve or at least get % opening reported back. Neither is possible.

 

I want to make it 100% clear: if anybody tells me the FGTs are not working for them, in their house, in their office, with their boiler control, in their climate... I believe them! I can only report about what I see, what I measure.

 

For example, regarding the "ext sensor is accurate". Here is a graph of a DS18B20 (black) sitting next to the BLE probe (red). As you can see the temperature difference is well below the tolerance of these sensors. But what you see on the red graph is that the FGT only reports the red dots. The DS18B20 in my case gets sampled every 2 minutes, that is why it has got so much more detail... But the FGT prober measures only about 0.25 °C above the other one and I can make no claims about absolute accuracy if this sensor. I can say, it will be more precise than +/- 0.5 °C

 

EDIT: the BLE probe reports every 10 minutes, but the FGT does not forward every sample to the Z-Wave controller. The 10 minute temperature report gets logged in the "blackbox logs".

 

If you look at the peak you may think it overheats. This is not the case. The valve is closed, the radiator is cooling... But we have some sunshine and this room has a window facing south-west. Also, due to "human activity" hot air gets mixed and this peak has nothing to do with the algorithm of the FGT...

 

This does not mean it is going to work in your house... I make no such claims.

Oh sorry, I thought you said that here. I'm following forums for quite a time already.

 

I don't have a problem with the external sensor, I think it measures the temperature somewhat correctly. At least I can compare it in the living room, where I have another dedicated temperature sensor and they both shows the same temperature.

 

 

My first TRV is 4.0 and to be honest, it works better than the rest. I bought recently the rest of TRVs (3) and they are 4.3.

 

I know I cannot upgrade firmware. I already sent a Fibaro my opinion about not providing firmware and I will be like an annoying mosquito to them. They released a product labeled as Z-Wave Plus. Z-Wave Plus is an open standard with OTA updates. Released product is broken and needs a firmware update. But in order to update the firmware, you need a proprietary device. This is in my books false marketing. Compare it to Hue bulbs. They're not labeled as ZigBee product and Philips specifically says that you need the bridge.

 

By the way, are you sure there aren't some secret commands? I've read somewhere, that you can set temperature range, where TRV can be configured to increase some temperature step by 0.5 degrees (I'm not sure if it was a threshold for TRV to be activated or something different) and I read that you can remotely calibrate heads via HC.

Hi All,

 

I'm relatively new here, but I've just got 5x FGT-001, and I'm not especially impressed either. They're running v4.3 which I can't upgrade without a tedious shipping process as I use OpenHAB as my Z-Wave controller.

 

Fibaro should, in my opinion, stop preventing users from requiring an additional item to upgrade z-wave+ compliant devices.

 

Anyway, from reading through the thread, it sounds as though the valves might work if I use them as simple on/off switches; is that right? I.e. I fully open them or full close them? If so, I can probably script some sort of  hysteresis myself.

Also, as far I as I can tell, I only get an update from the external temperature sensor about every 12 hours, even though the temperature in that room varies by ~10°C (yes, ten degrees centigrade) quite often

I can confirm that it does not work at all. 

Turning on and off works, but in this way your valve would make very many full moves every day so it drains battery very quickly. 

 

About temp update: open habmin and change pooling to 10 minutes. 12h is default. It will work

 

@tinman 

You are defending fibaro in every possible way and claim that users are mistaken... You said something like 'fibaro uses complex alghoritm to satisfy customers needs' so  I have one simple question about fibaro:

Please explain us when is reasonable to keep heating when room temp is 23,8 and setpoint is 16? That is how fibaro works. I have 3 pieces. 

I would say that it is extremely wrong behavior and telling about complex alghoritm when even the most basic case does not work is simply bulls..t

Hi
What is habmin.
There is nowhere I can change polling on my FGT and also ext. sensor.

Habmin is part of openhab used for management. You can install it from paperUI. You can edit configuration parameters of z-wave things if you do not have fibaro center. 

If you have fibaro center habmin is not needed.
