Nibe Integration: Bad logger message

[fBruckm]

The problem

I'm running a ESPHome UDP gateway connected to my Nibe F1145 heat pump and added the new Nibe Heat Pump integration in my home assistant installation. I was able to add the integration without error and it is shown in the integrations and devices overview.

After enabling the enteties corresponding to the datapoints that are also in my LOG.SET I get data, but a parsing error is shown in the log file, see "Anything in the logs that might be useful for us?".

The ESPhome gateway itself seems to be working fine. You can see the ESPhome configuration under "Additional information".

The Diagnostic log does not show any nibe related information, and therefore I did not attach it.

How can I to solve the error?

Any help would be appreciated.

What version of Home Assistant Core has the issue?

core-2022.12.8

What was the last working version of Home Assistant Core?

Same issue as here: yozik04/nibe-mqtt#15 had been solved upstream. So will be fixed on next version bump of library.

[elupus]

Should ve fixed now. You may get an warning in log still. You cant have 32bit registers in LOG.SET file.
