Binding Request : Buderus web gateway

frankie.delure · July 8, 2019, 3:45pm

Update / Solved: Followed the steps in post #113. Just ran the inbox search a second time and the items popped up.

I’m using the OH2 binding 2.5.0.SNAPSHOT. My MB Lan2 was detected successfully and after entering the key the device is now online. However, no channels or items are created. Understandably, nothing is displayed in the PaperUi.The debug log shows the following entries:

2019-07-08 17:30:46.182 [hingStatusInfoChangedEvent] - 'km200:kmdevice:45309xxxx' changed from INITIALIZING to ONLINE

So far I cannot understand what I can do more. Can you give me a hint?

HI,
you should see the thing in the inbox. Is it not appearing there?

Hi,

the “systemStates” extension is now merged into the master. The next OH full build from master should have this extension inside.

Greetings

Markinus · September 1, 2019, 5:47pm

Hi,

I took a look to the decimal places and I think it should be fixed now. It would be great if someone could test. Here is a new version. (Fixed to one decimal place)

Greetings
Markus

Oggerschummer · September 1, 2019, 6:43pm

Hi Markus,

thanks for taking a look into this.
I just installed the latest version and the temperatures now show up with one decimal except the supply temperatures: (Filtered on “supply” to shorten log):

Edit: Deleted the heatsources thing, removed the items and relinked them. Same effect, still values with many decimals.
Edit2: In Paper UI the values look good, rounded to one decimal.

HI,

hmm, that’s strange. There is no difference between supplyTemp and the other float values…

Greetings

frankie.delure · September 18, 2019, 2:08pm

I am having trouble to change the Refresh Interval from 30s default to another higher value, for example 120. It always gets back to 30 whatever I type in. My hope ts to reduce the size of the log file with less polling periods.

Oggerschummer · October 3, 2019, 9:11am

Hello Markus,

I finally took some time and updated to 2.5.0 M3 plus had one more look into the logs.
It affects all temperature values coming from KM200.
Below I filtered on the item “HeatSources_ApplianceSupplyTemperature”, which gives a good impression on what is going on. In some cases it actually does work, but there are others when it jumps from single decimal digit to full length, back to single digit etc.
Setting the items dimension to “Temperature” did just add the unit of measurement s expected, but the values keep jumping.

Somewhere in the code there seems to be a path where cutting the decimals is bypassed.

Kind Regards,
Oggerschummer

I have the same issues. Has this been solved yet. At least I don’t find this search term in this thread. Thanks.

Christof_Bodner · November 20, 2019, 8:37pm

I am running v2.4.0 Release Build and get the items displayed with a sitemap in BasicUI. I like this addon very much, thank you for a lot!

Now I would also like to change the target temperature, so I added as an item
Number T_Zieltemp_Nacht "Zieltemperatur Nacht [%.1f °C]" <radiator> { channel="km200:heatingCircuit:957210373:hc1:temperatureLevels_night" }
and in the sitemap
Setpoint item=T_Zieltemp_Nacht minValue=10 maxValue=20 step=1

When I move the slider, I get this log:

2019-11-21 23:16:55.362 [nt.ItemStatePredictedEvent] - T_Zieltemp_Nacht predicted to become 15
2019-11-21 23:16:55.376 [vent.ItemStateChangedEvent] - T_Zieltemp_Nacht changed from 16 to 15
2019-11-21 23:16:57.942 [vent.ItemStateChangedEvent] - km200_heatingCircuit_957210373_hc1_temperatureLevels_night changed from 17.0 to 16.0
2019-11-21 23:16:57.953 [vent.ItemStateChangedEvent] - T_Zieltemp_Nacht changed from 15 to 16.0

But the temperature at the heaitng is not changed when I look into the RC35. Any hints what’s going wrong? Thank in advance for your answers!

KR,
Christof

Markinus · November 23, 2019, 9:20am

Hi,
you are using the 1.0 items configuration on the 2.X binding. You have to remove it and create new from PaperUI.
Greetings

Markinus · November 23, 2019, 9:22am

HI,
you need some time. It can take some minutes till it’s activated in the heating system.
Does it work’s from the PaperUI?
Greetings

Markinus · November 23, 2019, 1:22pm

Hello Oggerschummer,

hmm, thats a bit strange. I will test something. Please use this version. Can you see any difference?
How are you testing it? A script? If it’s still not working then send me an example.
Greetings
Markus

Christof_Bodner · November 23, 2019, 7:10pm

Thanks fo your answer!

The change takes some time to be effective.

In PaperUI, there was a NaN in line “Zieltemperatur Nacht”, then I changed it there to 17. See a screenshot of this afterwards:
In Bildschirmfoto%20zu%202019-11-23%2019-38-11

If I check the setting at the RC35, it’s still at 18°C.

Then I changed “night” to 15.0 with the result that " Zieltemperatur Nacht" also changes to 15. Looking at the RC35, also no change, the temperature setting is still at 18°C.

I also set the mode to manual “night”, same behaviour, so the RC35 shows 18°C. The other way is working fine, so setting e.g. 17°C at the RC35, PaperUI and BasicUI show 17°C.

Markinus · November 23, 2019, 7:47pm

Hi,
I tested it just with my system and all stuff is working like expected. You can see it in the buderus app. If you change the target “day” value in OH (it’s active now) then the app shown the new value. (But you have to switch the sreens inside the app so it is able to read the new values from the device).
NaN is strange, does it always show NaN?
Greetings

Christof_Bodner · November 24, 2019, 11:21am

Hi,
Well with the App I get exactly what you are reporting. The setting in OH2 is also visible in the App and vice-versa. But the control RC35 on the boiler does not change. Maybe the problem is already in the App. I will contact Buderus help in order to fix this.
I’ll keep you informed about the status. Thanks a lot for the support!!!
KR,
Christof

Markinus · November 24, 2019, 11:35am

Hi,
in my RC35 it changes.
If you open the small flap on the RC35 there is a temperature button (next to the calender button), If you press it then it shown the actual set temperature and the measured temperature.
If I change the value in OH then a short time later the value changes there too . Without to close and open it again…
Greetings
Markus

Oggerschummer · November 25, 2019, 11:33am

Hello Markus,
just shut down OH, replace the binding in addons, cleared the cache with openhab-cli, restarted OH.

Result is a before, the log file shows that the values are more or less alternating between single fraction precision to unlimited and back.

I have no specific test script, the log shows the behavior:

ok, I created a new version with some output, you can download it here.
I would be great if you could test it, I’m testing a new OH service and cannot this myself.

Hello Markus,

from what I see in the log on level DEBUG the JSON contains valid data.
The Float-value logged after parsing shows to many fractions.
