Ledvance Smart+ Smart Ceiling Light

I have seen threads about integrating ledvance plugs. I have tried LocalTuya, but unsuccessfully. Thought I’d try my luck posting a new thread.
I have a ceiling lamp LEDVANCE.
I have it successfully imported into Ledvance Smart+ app. I tried to connect it to Tuya Smart app, no luck. It starts to pair, but then errors out.
Using the LocalTuya HACS integration, I tried adding the device without Cloud api. I enter all the details, but receive an error: “Connection to device succeeded but no datapoints found, please try again. Create a new issue and include debug logs if problem persists.”
Note, the Ledvance Smart+ app has multiple ways to get the device local key. One way is More → Voice Assistants → Home Assistant → Wifi → Device. This seems to suggest that it should be ready to include with Home Assistant, but how?
