Atomi Smart lighting is pretty popular, specifically in regions, where Costco is selling them.
They are connecting through Wifi and might have an API, but an integration with Homeassistant would make sure that brightness, light temperature and possibly scenes can be controlled in one environment instead of using multiple apps (HomeAssistant, Atomi Smart App) or external voise assistants (Alexa, Google)
I’m not familiar with Atomi’s lighting devices, however I have several Atomi smart tabletop heater AT1482’s (purchased at Costco US, however looks like Costco US no longer offers) controlled via tinytuya. They are just standard Tuya devices. Good hunting!
I’ve been trying to get my Atomi heaters working with home assistant. Can you explain how you got them working with Tuya? They don’t show up for me under the Tuya app, but maybe because I already connected them via the Atomi app? I’
You can “Remove Device” from your “Atomi” APP, then re-add it with the “Tuya Smart” APP.

P.S. It seems a lot of these cheap rebrands from china on amazon, might be using Tuya on the backend.
I tried to connect a new Atomi Smart string light to Smart Life and alternatively to the Tuya App.
It was not detected in either app. In the Atomi Smart app it was found and installed. Even if I remove it in the Atomi app, I cannot detect nor install on the Tuya platform.
Anything I still do wrong?

This along with another post elsewhere help me get my two AT3120 Outdoor Plugs connected to Tuya. My initial problem was that the Tuya app wasn’t discovering the devices. The other post recommended manually adding the devices. Facepalm moment for me. Like you said, my devices were indeed blinking fast, not slow. [shakes fist in air at Atomi]
Now… In a year when I need to reset them again, will I remember this post?
