I just set up one of these, and theres a trick to it to link to Alexa (if you can call it that).

If you look at the available device brands in Alexa, there is no Ultrabrite option so it DOES initially look like Teckin, which is listed is a better option (and choosing Other doesnt detect anything).

However if you go ahead with the Ultrabrite app to set up the device, you can look on the amazon store for the 'Ultrabrite Skill', and when you add that, the browser will ask you to put in your login, and Alexa wil detect your Ultrabrite devices without the need to go into the Alexa app to add devices manually at all.

It was actually easier than other devices Ive added via Tuya/Smart life etc.
