MQTT payload_template deprecated in autodiscovered device

As soon as I upgrade core to 2024.8.0 I get the deprecation of the “payload_tempate”

Problem is that the device is an autodiscovered thermostat, specifically the WThermostat BECA fas (see here )

I have no way to edit the configuration of the devices to change the “payload_template” to “payload”.
How can I fix the issue?
Any idea?

Report it to the integration code owner.

Greetings clemente3905,

The thing to do is add an issue to the github repo and provide all your data. The repo appears to be maintained and I bet the author will be able to help you.

The intention of

warnings is to get the original software author time to update the code to be able to use the software after the change.

Hi again guys.
I tried adding an issue to the github page but, apparently, nothing happens.

Let’s assume I would like to “try” to fix the issue myself.
Can you point me out to where I can find "how-to"s to fork, build, test and submit solution to github itself?
I have no specific knowlodge of github and its way of working, but I do have some general knowledge of programming, so I would like to try.

You have to wait for the developer to make the fix. This is open source, these people are volunteers. They do things at their own pace, not your pace.

There’s a fork button and a pull request button. The fork creates a fork under your user, the pull request creates a request to add code changes.

As for building and testing, that depends on what the library is using as a language. I suggest you google the language, the test suite and github. You’ll probably find tutorials.
