I found a cool actuator to open the window. It has a zigbee on board. Универсальный оконный привод Drivent - YouTube
Maybe someone is ready to order one for themselves and help with the creation of DHT?
I don’t read Russian, but it says it works with MQTT, so you could probably get integration that way.
As far as Zigbee, it depends What Zigbee profile it uses. If it’s Zigbee 3.0, it might work directly. But if it’s using a proprietary profile, it probably won’t.
