If a Yeelight device appears in the Mi Home app, does that mean it doesn't matter where I buy?

So basically I’ve put the EU server in the Mi Home app. I see that a Yeelight device is there (for example a light strip). Does that mean I can buy ANYWHERE the Yeelight light strip and connect it to the EU server?

No. You have to buy from EU to connect to EU. In MiHome. In Yeelight, it doesn’t matter.

Okay, thanks.
