Hi @umu_ugg , thanks for keeping localtuya alive!
I’m experiencing an issue, which perhaps you can help with. I have a Nedis Smart Plug which was working previously on HomeAssistant with rospogrigio’s localtuya. By accident I put it on pairing mode so I used the Tuya Smart app to bring it back to my wifi network. Homeassistant didn’t connect to it so I removed it and add it back on LocalTuya only to find the error: Connection to device succeeded but no datapoints could be found. Please try set-up again. If problem persists, create a new issue (including debug logs). . Meanwhile I’ve migrated to your branch of localtuya, version 2024.7.0, but I keep getting the same error… 
I know this smart plug is compatible with LocalTuya/HomeAssistant because I have a second one working fine.

“Nedis Smart Plug 1” is the smart plug that is essentially the same plug as the one I’m trying to add.
I’m not sure what’s going on or how to fix this. Any tips are welcomed. Thanks in advance!
