I recently purchased and successfully installed 3 Yeelight products: colored lamp, ceiling light and led strip. All connected to my account and works great with the Yeelight Android app.
I noticed that the Yeelight can also work with IFTTT and Google Assistant. When I've tried connecting my account to both, the colored lamp was the only recognized product.
I also tried logging out from the Yeelight Android app and log in again in order to make sure that all 3 products are indeed connected to my account, and they were all connected.
Appreciate your help connecting all 3 Yeelight products to my Google Assistant and/or to IFTTT.
