Hi Michael, would you be so kind and maybe share your message format string? I got the same software version and still can’t get it to run properly.

I have no access to my system at the moment. I can post it in 10 days.

That would be great. Thanks in advance!

Thanks for the message format. Unfortunately it still does not work for me. I don’t get anymore the message length error but now it just prints “Invalid State” and “Invalid value” in the logs. No entity holds any value…any idea?

EDIT: After some analysis I could see that the connection state toggles between ok and disconnected every 5 seconds… not sure why this happens.
Checking the connection on telnet directly is fine. There I receive constantly the messages

129

Could you post your complete nano_pk related configuration.yaml? Could be just a spelling error somewhere.

130

Here is my configuration:

nano_pk:
host: 192.168.0.41
msgformat: “NANO_V14HARp2”
devicename: Nano-PK
parameters: FULL
language: DE

131

same here connection is flapping every 5 sec

132

So you inserted the new message format in hargassner.py?
Did you tried to insert it directly in configuration.yaml? I know it shouldn’t make a difference, but worth a try.

133

no difference with the connection

134

For you the message length is still not accurate. It is missing 13 channels. “Expected 135, actual 122”

135

Today I got my new Hargassner Nano PK and I get the same error as the users above…
@Michael1101W could you please tell me, where exactly I need to copy your mgsformat? I’m still very new to Home Assistant, and don’t know where to put that exactly in the Hargassner.py…
Thank you very much! :slight_smile:

136

Just copying my msg format will not make you happy, most probably. Check in the GitHub folder for the instructions how to get the correct msg format for your system and where to add it

https://github.com/TheRealKillaruna/nano_pk

You need to extract it directly from your system as a lot of people do have different software versions. If this doesn’t work you can add the pull request from anderl78 to get more info why it’s not working. Maybe it’s just a wrong number of channels, which you can add manually.
Good luck.
If this is not working you can message me directly.

137

I made a new msgformat from my heating as the instructions said and added the new line in the hargassner.py and logged the data.
“HargassnerBridge.async_update(): Unexpected message length. Expected: 149, Actual: 118”
I tried a few different dummy entries, but the error is still the same as above with 118, even if I add 20 dummy lines to it.

So I tried to add the line directly into msgformat in the configuration.yaml instead of the “NANO_V14L” from the Github page.
“HargassnerBridge.async_update(): Unexpected message length. Expected: 116, Actual: 118”

Why is the expected line number changing from 149 to 116? And what should i do when my heating is sending 118 when only 116 are allowed?

138

Hi Guys, i’ve developped a project to pilot my NanoPK, including modifying the temperature, the boiler mode and the zone mode.

project can be found here: GitHub - hlehoux2021/MyHargassner: my personnal hargassner experiments

boiler is presented using MQTT-Discovery ; unfortunatly i’m not a home assistant user, but still it might be useful to share

Hi,

I juste updated to HA 2025.9.4 and the NanoPK integration is down.
Here is the log I got saying init.py file needs adjustements about :

“async_setup await hass.helpers.discovery.async_load_platform(‘sensor’, DOMAIN, {}, config)”

How can I manage to get it to work with last HA updates ?

Enregistreur: homeassistant.setup

Hi, I managed to get rid of this error updating my custom component using Anderl78’s fork : this specitfic modification manage to pass this error message.

However, my NanoPK12 has been updated to V14.0HAR.p2 this morning.
I had added my new MSGformat to hargassner.py file, adding a dummy channel (114 were excepted but 115 received).
To get it to work, I had to compare the data received from telnet and the MsgFormat expected.
I had to add a dummy Channel106 at the end of the Analog section, thanks to @skrue for the HowTo :slight_smile:

Thank you!!!
Finally it works again.

142

I tried now many things and played around a little but now I am stuck here:

HargassnerBridge.getStateClass(): Parameter key Verbrauchszähler not known.
HargassnerBridge.getValue(): Parameter key Verbrauchszähler not known.
HargassnerBridge.async_update(): Unexpected message length. Expected: 132, Actual: 134
HargassnerBridge.async_update(): Unexpected message length. Expected: 132, Actual: 134
HargassnerBridge.async_update(): Unexpected message length. Expected: 132, Actual: 134

Any idea what’s now wrong here?

What should I now add to the message definition?
What about “Verbrauchszähler”?

143

You need to add two dummy channels in your analog MSGFORMAT.
You will find the method to identify where are these here :
