Unable to discover the device (zhimi.airpurifier.ma4)

[poma]

Describe the bug
Unable to interact with device.

Version information (please complete the following information):

• OS: Ubuntu 18.04
• python-miio: 0.5.3

Device information:

• Model: Air Purifier 3
• Hardware version: zhimi.airpurifier.ma4
• Firmware version: 2.1.3.0022

To Reproduce

$ miiocli device --ip 172.16.*** --token *** info
Error: Unable to discover the device 172.16.***

• I verified that the device ip is correct
• I'm able to successfully ping this ip address
• My PC and the device are in the same subnet

Also tried doing this from a Mac (10.15.6, miio 0.5.3):

$ miiocli device --ip 172.16.*** --token *** info
ERROR:miio.miioprotocol:Got error when receiving: timed out
Error: No response from the device

[poma]

So how do I troubleshoot this?

[poma]

I tried to monitor network with wireshark and it looks like the device responds to handhakes:

> 21310020ffffffffffffffffffffffffffffffffffffffffffffffffffffffff
< 2131002000000000123d37c7000007c5ffffffffffffffffffffffffffffffff

Found the reason: outdated token

When I used -dd switch I saw errors like Unable to decrypt, returning raw bytes, looks like this is a clear sign that token is incorrect

The unable to decrypt message also gets printed during the discovery process, normally the incorrect token causes Got checksum error which indicates use of an invalid token error. Are you sure that didn't happen?

Glad you got it working though!

[poma]

Nope, got only this one. It happened when miio received a response to handshake
