Miio Xiaomi Air Purifier availability blinking ({'code': -9999, 'message': 'user ack timeout'}) #36972

denysdovhan · 2020-06-21T13:23:21Z

The problem

I have connected my Mi Air Purifier 3H (zhimi.airpurifier.mb3) via Xiaomi Air Purifier integration. This model is specified as a supported one.

However, I’ve noticed it gets offline from time to time, every 30-90 minutes.

If you take a closer look at the history graph, you’ll notice that availability is blinking and eventually it gets unavailable completely every few hours. Only rebooting a router and/or humidifier helps to get it back online.

Environment

Hey there @rytilahti, @syssi, mind taking a look at this issue as its been labeled with a integration (xiaomi_miio) you are listed as a codeowner for? Thanks!

hapklaar · 2020-06-22T10:13:46Z

I suspect this to be a hardware issue. The 3H unit is responding very badly to pings and requests. I see a constant ping response time in the hundreds of ms and even timeouts, with the unit next to my access point.

denysdovhan · 2020-06-22T11:08:35Z

Having bad pings is OK - it doesn’t break functionality. I’m worried about purifier getting completely unavailable after some time.

This usually happens every 6-12 hours for me and requires reboot of router and Home Assistant.

hapklaar · 2020-06-22T11:29:42Z

Having bad pings is indicative of the responsiveness of the unit, this will also reflect in its reachability from HA. However I don't have the issue where I need to restart anything to get it working again. It just doesn't respond very often.

denysdovhan · 2020-06-24T11:43:38Z

Seems like I have managed to fix purifier getting completely unavailable every few hours. I manually specified my model:

fan:
  - platform: xiaomi_miio
    name: purifier
    model: zhimi.airpurifier.mb3 # I specified my model here
    host: !secret purifier_host
    token: !secret purifier_token

After that change, my purifier is still up for more than 48 hours.

However, general availability is still blinking:

mrfoxbit · 2020-07-02T07:12:31Z

I have the same issue

rytilahti · 2020-07-02T10:09:28Z

Could it be related to cloud connectivity issues? Some xiaomi vacuums are known to have issues if the packets are simply dropped, see https://python-miio.readthedocs.io/en/latest/troubleshooting.html#intermittent-connection-issues-timeouts-xiaomi-vacuum

Sometimes 'user ack timeout' indicates that the command is not supported by the device, but consider it is working sometimes that shouldn't be the case..

denysdovhan · 2020-07-02T12:40:56Z

After upgrade to 0.112, my purifier gets completely unavailable. Restarting HA, router, or purifier doesn't help.

rytilahti · 2020-07-02T12:50:09Z

See the already linked 'command error' issue which is the likely the cause, that is however a different problem than this 'user ack timeout' issue.

denysdovhan · 2020-07-02T13:41:09Z

I've rolled back to the previous 0.111.* release.

rytilahti · 2020-07-02T19:46:12Z

And it is working just fine with it? Maybe there are differences between devices/firmware version/something, that is causing the timeout instead of that command error. In that case this would be a duplicate of that issue.

matteos1 · 2020-07-03T07:38:22Z

ade to 0.112, my purifier gets completely unavailable. Restarting HA, router, or purifier doesn't help.

also for me, the update of ha to 0.102 has made the purifier 3h unusable. its status is: not available

KoltesPunti · 2020-07-03T12:37:09Z

After update i got the same problem :/

rytilahti · 2020-07-03T12:50:48Z

For 'command error', see #36993 which will be fixed with a new python-miio release, sorry for the inconvenience :(

mrfoxbit · 2020-07-04T15:21:56Z

Still error in HA 0.112.2 and python-miio 0.5.2.1. My device is Xiaomi Air Purifier 3 (zhimi.airpurifier.ma4)

@balloob please, reopen this issue. The error message persists in logs.

AdrinkBeer · 2020-08-02T17:59:18Z

FYI, I have upgraded to HA 0.113.3 (with the bump of python-miio) but still have an issue (Xiaomi Air Purifier 3H).

2020-08-02 16:16:50 ERROR (MainThread) [homeassistant.components.xiaomi_miio.fan] Got exception while fetching the state: {'code': -9999, 'message': 'user ack timeout'}

No discovery issues in my logs (python miio fix).

rytilahti · 2020-08-02T19:37:43Z

Okay, let's reopen this, but I don't really know what would be a suitable fix for this. That {'code': -9999, 'message': 'user ack timeout'} message is coming from the device itself, so for some reason it fails to execute the called method.

On potential way to alleviate this would be either to retry (or ignore it from homeassistant's side and keep the old state) but it feels a bit hacky solution.

alive-corpse · 2020-11-14T22:38:48Z

The same issue (user ack timeout) with model zhimi.humidifier.ca1 (Air Humidifier v2)
Home Assistant 0.113.1
python-miio==0.5.2.1

On potential way to alleviate this would be either to retry (or ignore it from homeassistant's side and keep the old state) but it feels a bit hacky solution.

I think it's really better than got log full of this messages.

syssi · 2020-11-19T06:39:34Z

@alive-corpse Could you check the error of your device (CA1) a second time? It's a "user ack timeout" or "UART timeout"?

0rsa · 2020-12-03T02:24:16Z

I add myself to this thread
Using
miiocli device --ip IP --token TOKEN info
It works:
Model: zhimi.airpurifier.mb3 Hardware version: esp32 Firmware version: 2.0.5

Using
miiocli airpurifiermiot --ip IP --token TOKEN status
It doesn't work:
Error: {'code': -9999, 'message': 'user ack timeout'}

miiocli, version 0.5.4

freddieleeman · 2021-01-02T09:47:07Z

I'm getting a lot of these too:

    Got exception while fetching the state: Unable to discover the device 192.168.254.156
    Got exception while fetching the state: {'code': -9999, 'message': 'user ack timeout'}

Retrying the call with a small timeout and a limit of x retries would probably be a good fix.

I don't know, I'm still learning Python. But as a quick fix setting self._available (line 1097) of fan.py to True would probably fix the unavailable messages. But this is not a good fix in any way, so we should probably wait for someone with more talent then me to resolve this issue.

Would be nice to have some working solution

0rsa · 2021-01-11T14:48:01Z

Restart your purifier.
If you connect to it after restarting, I agee that it happens when you are querying your purifier too many times in a short delay. I use node red and I can set querying delay, I have no more problem increasing this delay.

Great suggestion
Mind sharing your nodered recipe?

0rsa · 2021-01-11T15:12:10Z

I use https://python-miio.readthedocs.io/en/latest/ with an "exec" node (executes a system command)

I increased querying time from 5s to 30s.

syssi · 2021-01-11T16:56:41Z

If you want to reduce the update interval you could change the scan_interval. cp.

https://www.home-assistant.io/docs/configuration/platform_options/

SeraphimSerapis · 2021-01-11T20:51:43Z

Where does the component increase the scan_interval? fan by default uses 30s and I haven't seen any different in xiaomi_miio:

core/homeassistant/components/fan/__init__.py

Line 27 in 13cdf0b

SCAN_INTERVAL = timedelta(seconds=30)

syssi · 2021-01-11T21:06:05Z

@SeraphimSerapis You are right. The component uses the default value.

freddieleeman · 2021-01-11T21:53:26Z

I've tried adjusting the scan_interval, but it doesn't solve the issue for me. Although less, I still get 'unavailable' status.

Seba200086 · 2021-01-11T22:54:44Z

Same here - set scan_interval: 60, but I'm still getting:
[homeassistant.components.xiaomi_miio.fan] Got exception while fetching the state: {'code': -9999, 'message': 'user ack timeout'}

Additionally, I noticed that this parameter has no real impact on refreshing, e.g. AQI value refreshes irregularly every 3 to 20 minutes.
I also noticed that with longer refresh intervals it helps to use Mi Home application (it forces values to refresh).
