@rytilahti I have this device, is there anything that I can do

[wzhd]

Mine just arrived and I did a little packet capturing.

It first did an HTTP request:

GET /gslb?dm=ots.io.mi.com HTTP/1.1
Host: dns.io.mi.com
User-Agent: MIoT

The User-Agent is particularly concerning. The reply contains just a few IPs:

{"info":{"host_list":[{"ip":"<redacted>","port":443},{"ip":"<redacted>","port":443},{"ip":"<redacted>","port":443}],"enable":1},"sign":<redacted>","timestamp":"1580070784"}

The rest are mostly TLSv1.2 communications with one of the returned IPs. The server name is Mijia Cloud.

It did send some UDP packets from source port 54321 to dest port 8053.

I wonder whether it's a miot device.

If you can obtain the token, you could try to execute miot_info command to see how is it responding. If it is a miot device, it will (hopefully) respond to that call.

The miot support is still WIP and there are a couple of PRs where the work is being done, but if it's a miot device, we can use the description files to help adding a preliminary support for that device. Otherwise it will require deciphering that udp device communication (which can be useful anycase, as the description files are not always complete).
