I mean yes, partly 
Some sellers, like Moes or others also sold “real” T6E devices, until they released their new version. So there was a time when you could get a “real” one from other sellers than Smatek.
I also did some research about that some time ago and stumbled over their Alibaba store. Sadly the minimum order is 5 or 12pcs and shipping costs are ridiculous. Understandable, as Alibaba is B2B, so…
I’m really also interested in the 6, 8 or even 10.1" display they have, but… way too expensive right now sadly: Tuya Android Panels - SMATEK-Home Automation Smart Control expert
