Everyone here is right, but I want to add a couple of things from my own experience, since I've dealt with this myself. yeah, there's no direct Aqara support in Yandex Smart Home, that's a fact, but there are a few workarounds. the most practical way is to use Home Assistant or some other automation system that can work with both ecosystems at the same time. like, Home Assistant will connect your Station and Aqara to each other through a local network, and then voice commands will go through the Station to Home Assistant, and from there to Aqara. though, this requires some setup skills, it's not for complete beginners.
there's also a simpler option - if you have an Aqara hub (there are several types), it can work with Home Assistant through a local connection. I set it up that way myself, actually, because I got tired of waiting for official support. it takes about two or three hours the first time, then it works like clockwork. plus you can also try adding Aqara devices to Home Assistant directly, if they support direct Zigbee connection, but for that you need a separate Zigbee adapter.
anyway, if you need it right now with no hassle - you're stuck needing a third system. but if you're willing to spend some time, everything is totally doable. I wouldn't even advise locking yourself into one ecosystem in 2026, companies too often kill support or change the rules of the game.
