Can I use tuya RGBW light on local?

I interested in RGB mood lamp.
I found lamp that is available control with tuya

Tuya online is two slow senstive, So I want to control on local tuya.
Can I control RGBW lamp with local tuya??

Interested in this is well. Anyone have one and open it up? I assume there’s an esp8266 in there? My kids want a night light so debating on one of these or just getting an rgbw bulb and sticking it in a lamp.
