Any way to make Xiaomi sensors appear as Alexa Device?

Can anyone advise on whether it’s possible to expose a Xaiomi sensor (temperature or door) to show up as a device in my Echo? My sensors are connected to my ST hub. I dont have a Xaiomi hub.

If you are interested in Alexa knowing what temperature is at a specific sensor, all you need is to add the thermostat capability to the DTH. So yes, it’s possible to have Alexa discover your sensors but requires modifying a few line of codes in the DTH. Only temperature is currently supported by Alexa natively. Exposing other capabilities can be done via a custom Alexa integration, such as this awesome app.
