I own this product, and I have attached the PDF manual for the device. There is no branding on the device itself, except for the model number on a sticker underneath.
I googled the model number and found this manual. The company name is actually iSmart Cities (Zhuhai) Limited, I just assumed Zhuhai was the Chinese company name (based on the ZL tag prefix Zhuhai Ltd -> ZL).
But looking closer, I see that's just the city name, whoops!

Of course, this doesn't affect the code, happy to supply more information if you want it.

Mike.
