How reliable is the Firmware Update Download Link and what can happen if I pick the wrong software?

Hi everyone

First of all: Your work is amazing ❤️! I enjoy this integration so much.

I was excited as it even showed me that the firmware of my heatpump can be updated. I tried to figure out which firmware to download before I used this integration. But I really was not sure how to reliably find out which model I really have. Now the integration shows me following information:

Luxtronik Firmware Version
Installierte Version: V3.88.0
Neueste Version: V3.92.1

For your https://www.heatpump24.com/DownloadArea.php?layout=0None LW 8 (Download ID 2) is https://www.heatpump24.com/software/fetchSoftware.php?softwareID=2Firmware Version V3.92.1 available.
https://www.alpha-innotec.com/de/services/kundendienst/software-centerFirmware Update Instructions

The Install button below has no function. It is only needed to notify in Home Assistant.

Alpha Innotec doesn't provide a changelog.
Please contact support for more information.

Are we sure that the download ID 2 is correct? What if I pick the wrong Software and upload it? When I visit https://www.heatpump24.com/DownloadArea.php?layout=0 I can't find the WP Type LW 8. I am confused...

Thank you very much!

The model name and software don't necessarily have to match. At least that's the case with my LW81: Home Assistant and Luxtronik both display L1A.
The most reliable way is to check the heat pump's nameplate. It's located on the heat pump itself. Alternatively, you might find more information via the control panel. See this video (time index 0:20-0:38): https://www.alpha-innotec.com/de/service-und-support/downloads/software-center

I recommend verifying the software changes. There might be some unwanted changes. In my case, the latest version changed the behavior of Party Mode in relation to lock-out times, which is why I won't be upgrading.

https://myuplink.com/ is an easy way to automatically update using the right firmware. It's not the most reliable, so sometimes, I still need to update by hand.

Before using myuplink, I used to heatpump24 link and it always worked.

@AJediIAm @MrEarl Thank you very much or your reply.
I tried the way with the control panel and the sticker. But I can't find any match:

Is it because it is a Aeroheat from CTA and not Alpha Innotec? At least the software is from Alpha Innotec.

[MrEarl]

Yes, what you have definitely looks like a Luxtronik which is used by Alpha Innotec, Siemens Novelan, etc. and apparently CTA as well.
I fear, regarding your original question, I'm out of ideas.

Maybe try myuplink. If it works, it will select the right firmware for you
