[miio.miioprotocol] Got error when receiving: timed out

[ptc]

After setting everything up, I get the following error on HA restart:

[miio.miioprotocol] Got error when receiving: timed out

I retrieved a token using miio tool. Connected the fan to WiFi afterwards using mihome app. Any hints?

I have the same problem too using the same steps.

Is it because I have updated to the latest firmware?

I am on running on the same issue. Getting the token using miio discover worked, but it does not work in HA.

I am currently trying get more debug messages.

Any news on that? Did you get it working?

This is what I get when enabling debug level:

Unable to decrypt means the token is incorrect.

I also tried miio discover (via fans own WiFi) and that returns a token. But: after the fan is configured to your own WiFi, the token changes. Since miio discover doesn’t return a code after WiFi client configuration, I found recovering a (new) token from a phone backup works OK.

@mpepping i cant even connect it to Mi Home on Android. I use China mainland as region but it never finds the fan? Any ideas? I tried setting wifi info manually with miio configure then it will connect to my WiFi but i cannot access it with cli tools like miio. Token is unknown: ` INFO Discovering devices. Press Ctrl+C to stop.

Device ID: ID Model info: Unknown Address: 192.168.0.205 Token: ??? Support: Unknown `

[mpepping]

The Token: ??? line means that the fan is connected to your wifi. It won't expose a token, which is wise because otherwise anyone on your network can potentially read the token.

I used these steps to recover the token from a phone backup: https://python-miio.readthedocs.io/en/latest/discovery.html#tokens-from-backups

Changing regions to China should not be necessary. Just add the Fan in Mihome via the ➕ sign.

Hope this helps.

@mpepping i understand that part but my Android phone cant seem to find the fan. What are recommended settings?

[mpepping]

I used an iPhone. It shows an 'add new device' button in the app. Do you have Bluetooth enabled? Think that's used to initially 'find' the Fan.

[BenjaminFaal]

Yes with bluetooth enabled and i also tried on other devices.

[mpepping]

Don’t know man. Press and hold both buttons on the fan until beep for factory defaults and retry? Maybe reinstall the app as wel.
