Hargassner heating integration

TheRealKillaruna · April 15, 2024, 7:22am

This is fixed in the current version, please update your files from github.

xs400dohc · April 15, 2024, 9:41am

Thank you for the quick answer.
As far as I know, I used the latest files.

But I got it working fine by comment the line 7 out (#from apscheduler.schedulers.background import BackgroundScheduler).

Just for my understanding: Where and why apscheduler ist needed? For me, it works also without apscheduler.

xs400dohc · April 15, 2024, 9:45am

Me once more.

Just figured out, that in my manifest.json apscheduler was missing in requirements. So I did not used last version. Sorry for that. Now it´s working. Thanks for your help and your work on the integration.

But the question why it works without apscheduler is still open.

Sorry if this has been covered and I missed it. Is it possible to use this integration “through” the Hargassner internet bridge? Or do you need the heating plugged in directly on the LAN and you can only have one or the other?
Thanks in advance.

xs400dohc · May 2, 2024, 7:25pm

Hi t2njgttn,

the integration uses telnet to get the data. So you need to connect the heating to your lan. But to push the data to the internet, the heating should have an internet-connection. In my case via my internet-router.

Still no change after update the integration and Home Assistant.

Getting these errors:

Any ideas?

xs400dohc · May 6, 2024, 8:24am

I have had also this problem. After investigation I recognized, that the heating made an update to version V14.1HAR.pr_FT. After update the hargassner.py with the parameters of the new version (as discribed in the github-readme → How to use with other Hargassner models or different firmware versions), it’s working as before.

Spacey · May 13, 2024, 1:19pm

Confirmed - Integration stopped for me several days ago as well - I just re-did the logging-part, entered my new DAQPRJ string and now it’s working again.

xs400dohc · May 13, 2024, 7:06pm

Fine to hear that your integration is working again.

schousda · May 19, 2024, 6:38pm

Hello,
i tried to make this integration work today.
Could anyone please tell me where exactly i can find the firmware version of my Hargassner nano-PK heating?
I had a look at the options, but didn’t see it.
Thanks.

Ah… that Issue is already reported:

chefkoch · July 19, 2024, 10:59am

My NanoPK did an update to V14.0HAR.p
Since that HomeAssistant cannot read the values anymore. Has anybody else observed this ?

xs400dohc · July 20, 2024, 10:54am

see my post from may 6. Just update the hargassner.py with the new value-map.

chefkoch · July 21, 2024, 8:04am

Works !
Thanks a lot !

Hello,
since the update of Home Assistant this week, the integration stopped working.

Hi,

The problem does not seem to be with HA in general. I have read out my heater and realised that an update has taken place:

2024-08-30_15:12:17 KD=Hargassner
2024-08-30_15:12:17 KT=Nano.2(.3) 15
2024-08-30_15:12:17 SW=V14.0HAR.p1
2024-08-30_15:12:17 HW=V1.2.4
2024-08-30_15:12:17 UPDATEDATE=29.08.2024 13:32
2024-08-30_15:12:17 UPDATE=V14.0n3

HA-Version:

Core 2024.8.3
Supervisor 2024.08.0
Operating System 13.1

I also thought that the msg format had changed again but after reading and saving again the error persists:

HargassnerBridge._update(): Received message has unexpected length.

Has anyone already found a solution to the problem?

Marcel54464 · September 3, 2024, 9:29am

Hi,

it seems that others still have the same problem:

Solution has not yet been found.

xs400dohc · September 3, 2024, 5:32pm

Did you update your hargassner.py with the actual value-may? How to-> see my post from may 6th.

Spacey · September 9, 2024, 6:55am

Everyone pls check that topic @ GitHub - seems like adding 2 dummies at the end of the analog sections seems to help.

schousda · October 3, 2024, 2:29pm

Hello,
i want to use this integration for my NanoPK, but looks like the message format is different.
If i try to use the logging to SD card, it always tells me, that there is no SD card present. Are there any limits about size or anything else? I formatted it in FAT. Ist that correct?
Maybe someone already has the correct message format for this model?
Thanks.
