pin_mapping.json for Tremex OpenDTU missing after Firmware upgrade

[KlausHB]

Hi,
I managed to upgrade my Tremex OpenDTU I bought via Amazon in 2023.
But after the upgrade to v25.2.3 the pin_mapping.json is missing.

Is there any resource out there to download the file?
Does anybody has the same device and might post the pin_mapping.json here?

Thanx a lot!

The pin mapping file is available for download on the tremex / diamex website.

Cool!

I was on tremex.de before, but there were only 2 website-tiles to go to diamex and LED-Genial.
Now I found something here:
https://www.diamex.de/dxshop/0-Mwst-DX-DTU-Klassik-mit-kleinem-OLED-Display-096-242-cm

The filename of the configuration file is "dx-dtu.json"
Can I just rename it to pin_mapping.json and upload it?

The file contains 3 DTU-models. Do I have to delete the models I do not own?

No need to rename, just select the file and upload as pin mapping. Once done, activate the profile of your DTU model in the OpenDTU hardware settings page.

SUPER!!!
It worked. So I can empty my battery over night via OpenDTU.
tomorrow there will be a lot of solar power here again.

Thank You VERY MUCH for the quick help ms49434!!
