Sorry this binding won’t work with Mi Air. But I found something interesting regarding this cloud solution - look here: https://github.com/louisZL/aiot-open-2b
There seems to be some cloud platform documentation and it has BTW support for this Xiaomi gateway with codename lumi.gateway.v3 (https://github.com/louisZL/aiot-open-2b/blob/master/resource_definition.md).
Maybe it supports other xiaomi products as well…
