miio --discover fails to recognize gateway 2 about miio HOT 4 CLOSED

Thanks for your report! This is because the current version only uses a lookup of a hostname to determine the model of a device. When it actually connects to the device (as --discover does) it sees that is a gateway and that automatically discovers the subdevices.

I'm currently thinking about a new way to determine the model and tracking the progress in #27.

Thanks for your reply. In order to help you figure out the best way to discover gateway, I'd like to share what I found:

https://github.com/louisZL/lumi-gateway-local-api

It is not a code repository but a document one. There are many .md files written in Chinese but I believe you can use google translation. The repository seems to have all of detail in regard to gateway and I wish it would help you.

In regard to gateway discovery, maybe you can use heartbeat message which is sent by gateway repeatedly(perhaps every 10 seconds) like the following:

{"cmd":"heartbeat","model":"gateway","sid":"286c078911ea","short_id":"0","token":"BaY3p3mZ90Jszl3O","data":"{"ip":"192.168.31.207"}"}

It does't say gateway 2 or 3 but at least it says "I'm gateway" and ip address too. The packet is sent from 4321 port of gateway to 9898 of 224.0.0.50 via udp multicast when local communication mode is on.

Thanks, that's a good resource and is how support for the gateway is currently implemented.

The gateway version is determined by the model info, and based on the inspect you posted it looks like you have the 3rd version.

Version 0.15.x has implemented better support for discovery the model of a device. Hopefully this will have resolved this issue.
