Anova integration stops updating after a while, despite the fact that the device is continuously connected and the app works

rccoleman commented 2 months ago

The problem

I have my new Anova Precision Cooker 3.0 connected to my local wifi network and to the Home Assistant integration. It works well for a while, but then just stops updating for no apparent reason. Reloading the integration or restarting HA recovers the connection. The Anova iOS app continues to work to send commands and to reflect changes that I make on the Anova device manually.

I've seen this many times over the past week or so and have been monitoring the logs for issues, but I don't see any errors or reason for it. It's like the update coordinator just stops being called, and reloading the integration from the Integrations page gets it working again.

What version of Home Assistant Core has the issue?

core-2024.9.1

What was the last working version of Home Assistant Core?

No response

What type of installation are you running?

Home Assistant Container

Integration causing the issue

Anova

Anything in the logs that might be useful for us?

I turned on debug logging and I can see the integration regularly updating the Anova data, but then it just inexplicably stops. The last message is just a normal update:

How long does it normally take until it stops working?

rccoleman commented 2 months ago

I reloaded the integration around 7PM last night because it had stopped working, it worked during my 30min cook time, and the log indicates that it stopped updating just after midnight. I confirmed that it's no longer reporting status this morning. If I don't have debug logging enabled, there's no indication in the log at all about whether it's working or if/when it fails.

From the response from the API, I can see that it hasn't disconnected in a few days (when I unplugged it and plugged it back in):

'lastDisconnectedTimestamp': '2024-09-09T16:00:29Z'

Edit: I just looked at my logs and I see that it stopped updating about 14 minutes ago. The last debug message was:

I'm also missing some of the sensors mentioned in the documentation, but maybe my unit doesn't report them. This is the output from an update while it's cooking, but not yet up to temp:

I'll grab another when it's up to temp and has started cooking. The "remaining time" sensor is the one I'm most interested in, as I currently have to derive that in a template sensor from the state of the device and whether it looks like it's reached the target temp.

Here's what a report when it's reached the target temp:

Definitely looks like some useful data in there: activeStageMode transitions from entering to running when it starts to cook, for instance. At least being able to grab the startedAtTimestamp would be helpful.

I added some debug info in the message handling loop in anova-wifi to see if it's dropping out, hanging reading from the websocket, or raising an exception, but it's still running fine this morning. I'll keep an eye on it and report back if I find something.

Edit: So it just dropped out of the message processing loop for no obvious reason:

Here's the debug I added:

    async def message_listener(self) -> None:                        
        try:                                         
            _LOGGER.debug("Starting listener")
            if self.ws is not None:                  
                _LOGGER.debug("Websocket opened")
                async for msg in self.ws:
                    _LOGGER.debug("Waiting for message")        
                    self.on_message(json.loads(msg.data))
                    _LOGGER.debug("After processing message")
        except Exception as e:
            _LOGGER.debug(e, exc_info=True)                                
        _LOGGER.debug("Exiting listener")

No exception, it just dropped out of the for loop. I guess the websocket is closing, so I could just try to reconnect when it happens.

I've been monitoring this over the weekend and I haven't seen it fail yet. I added the following at the end of message_listener, but I haven't seen it actually happen in the logs and it hasn't stopped updating.

        _LOGGER.debug("Exiting listener, restarting")
        await self.connect()

I'm still trying to track this down without much success. In the end, the I get an ABNORMAL_CLOSURE from the aiohttp websocket and it's never able to recover even if I disconnect and reconnect the websocket:

After that, I just keep successfully opening the websocket and then immediately see the ABNORMAL_CLOSURE return code.

This is what I get from the aiohttp docs:

ABNORMAL_CLOSURE¶ Used to indicate that a connection was closed abnormally (that is, with no close frame being sent) when a status code is expected.

I'm now wondering if there's something broken in the aiohttp session that's passed in when creating the AnovaAPI class instance :shrug:. I can often "fix" this by manually reloading the integration, but that didn't help this last time. It always comes back up find when I restart HA.

Interestingly, it's almost like the socket goes into non-blocking mode somehow. If I keep reconnecting the websocket whenever it closes, I do still get messages on the websocket periodically before it closes (again).
