Issue with Eurom heaters

[jandy123]

Hello,

I've been trying without luck to get eurom heaters working with the latest tuya local and hassio core. The errors I'm getting are below. Basically the integration never starts properly. With an older tuya local version and older hassio the devices did work without issues. Any clue how to fix the error below?

Thanks!

You have an invalid config file with no entities defined. Most likely more than 1 year old and maintained outside of this integration so was never updated for the change to config format in January 2025.

Well, first I've tried to start fresh, and deleted all my devices (the 4 eurom heaters above) and removed the old tuya local. Then I installed the new version, added the 4 heaters, but the integration never starts properly, even after multiple restarts of homeassistant. I've tried also to go back to the older tuya local that used to work with a 2025 hassio core, unfortunately to no avail.

Could you please let me know what I could still try?

Ok, you were right regarding the invalid config file.

After removing my old tuya local, restarting HA and reinstalling the new tuya local, I had more success. I managed to add two of the heaters, but the other two are detected as IR heaters and report wrong temperatures, settings, etc. The problem is that the FW version is different and also the tuya protocol. I need to force a specific heater type (Eurom Heater 400W), which is not in the choice list. The others were detected as generic heaters, but it seems that they do work. So ow I'm stuck with the other two (tuya protocol version 3.3). Is there a way to change the config file and or model?

Thanks!
