Losing connection

[palmedia]

I'm testing the iKamand in Home Assistant. Every time after +- one hour the connection is lost. When I reload the intergration it is working again.

System log:

2024-01-29 12:32:14.559 WARNING (SyncWorker_3) [urllib3.connectionpool] Failed to parse headers (url=http://192.168.178.162:80/cgi-bin/data): [MissingHeaderBodySeparatorDefect()], unparsed data: 'HTTP/1.1 200 OK\r\n\n'

The iKamand is still accessible direct on IP. It looks like the session is expired (?)

[palmedia]

And again after 3 hours and 10 minutes the connection with the iKamand is lost.

[plmilord]

The error you displayed ("HTTP/1.1 200 OK\r\n\n") is normal... The iKamand module contains a header error which causes difficulties with the http library.

Concerning the loss of connection, when testing your iKamand, can you also run a "ping -t....." to validate the connection from elsewhere...

Let me know the development.

[palmedia]

The iKamand is still accessible (and pingable), while Home Assistant not registering any temperature updates anymore.

For example:

Probe1 and iKamand temp are both 19:

But if I request the data directly from the iKamand via http://::ip::/cgi-bin/data the temperature is 18:

time=11075&rm=0&acs=0&csid=&cm=0&ag=0&as=0&pt=18&t1=19&t2=400&t3=400&dc=0&tpt=0

So it looks like Home Assistant is not getting any new data.

Looks like the integration just stops requesting data. If I re-init the intgration it requests /info and after that it is requesting /data again.

Maybe it's because self._online is set to False after 1 bad response? Maybe it's better to try for like 10 minutes to see if the iKamand is back online after a bad respone / failure?

[plmilord]

I'm going to test over a long period with my iKamand... maybe I could set up a keep alive call at x frequency to bring on track the iKamand.

2024-02-08 06:37:01.554 WARNING (MainThread) [homeassistant.components.sensor] Updating ikamand sensor took longer than the scheduled update interval 0:00:01

I did some debugging myself. After the last WARNING noting happens. It's strange that the time between the last call and the exception is more than 15 minutes. As far as I can see is the connection to the iKamand succesfull. The exception says it can't update the sensor.

Changes I made for this debug data:

    async def get_data(self):
        """Get grill data."""
        url = f"{self.base_url}data"

        while True:
            loop = asyncio.get_running_loop()

            _LOGGER.debug("ikamand.py: get_data loop")
            try:
                response = await loop.run_in_executor(None, lambda: requests.get(url))

                if response.status_code in GOOD_HTTP_CODES:
                    result = parse_qs(response.text)
                    self._data = result
                    self._online = True
                else:
                    self._online = False
                _LOGGER.debug("ikamand.py self._data = %s", self._data)

            except requests.RequestException as ex:
                self._online = False
                raise HomeAssistantError(ex.error_description if ex.error_description else ex.msg) from ex

            except Exception as ex:
                self._online = False
                raise HomeAssistantError(ex.error_description if ex.error_description else ex.msg) from ex

            await asyncio.sleep(5)

[plmilord]

We can add a timeout in the get request... then we will need to catch the Timeout exception... But when this happens, what do you do to resolve the situation?

The code might look like this:

async def get_data(self):
    """Get grill data."""
    url = f"{self.base_url}data"

    while True:
        loop = asyncio.get_running_loop()

        try:
            response = await loop.run_in_executor(None, lambda: requests.get(url, timeout=10))

            if response.status_code in GOOD_HTTP_CODES:
                result = parse_qs(response.text)
                self._data = result
                self._online = True
            else:
                self._online = False

        except requests.Timeout as e:
            self._online = False

        except requests.RequestException as e:
            self._online = False

        except Exception as e:
            self._online = False

        await asyncio.sleep(5)

If you can try that on your side, that would give some ideas... You can add the LOGGER elements that you proposed to better see what is happening.

If this works for you, I'll see about adding this timeout processing to all post and get calls.

[veetek22]

I would like to test it as well - do I replace the code in ikamand.py between lines 76 and 99 ? sorry im not too savvy when it comes to that

Thanks, I will give it a try. I've added some debugging and now testing it.

Yes, replace these lines and restart HA. If you past the function in ikamand.py, pay attention to the indentation of the lines.

[veetek22]

Thank you trying now

[plmilord]

Tests are underway here too... Report your findings.

[plmilord]

During a 17-hour run, I had 5 small glitches (delay of 21s) and 2 long glitches (3m45s). Each time, the component resumed communication on its own... Still in control of the iKamand this morning!

On your end, has the component resumed or completely stopped responding after those glitches?

The integration stopped working.

[palmedia]

I did another duratingtest. Looks like the connection was lost but after a couple of minutes it restored itself and was recieving data again.

But after the hiccup the climate integration was nog "heating" anymore. So if I use this on my BBQ the iKamand stops keeping the BBQ at the right temperature.

Also time value resets:

@palmedia , have a look to the new release v1.5. It improves the stability of the component... but perhaps not up to your expectations! For my part, after returning from a loss of network connection, the display resumes where it was. Obviously, if the device resumes after a loss of electrical power, it resumes in neutral.

[palmedia]

Thanks for the update. I'm going to do another duration test. I also wrote an automation for changing the state to heat after a loss of network connection.

I also discovered that sometimes the iKamand loses its network and doesn't come back. For this I will connect a wall plug to give the iKamand a complete reset.

[plmilord]

I have not experienced this state which does not return to heat...

The only time my iKamand didn't recover on its own was when I unplugged and reconnected the power (this only happened once, and I wasn't patient! I have already observed the iKamand absent for 3-4 minutes).

As the iKamand seems to reset its probes after a power outage or loss of connection, I no longer consider its values in its first 40 seconds of its life. Its values are not relevant and precise during those first 40s of life.

[palmedia]

If the connection is lost, hvac_mode and temperature both resetting to off / 0 degrees. Even if the connection is lost for a couple of seconds / minutes.

I wrote an automation and added some values to restore the settings after connection loss. I've added also a probe target temperature for future notifications.

Variables are in dutch.

[plmilord]

hmmm... experienced that stoppage!!

I'm going to add code to resume where it was before the shutdown which occurs every ~6:30. It makes me think of other things...!! I'll come back to you shortly with another version!

[plmilord]

Have a look at the v2.0 Pre-release.

This should be much better for you. I think you will no longer need your automations.

...Lots of improvements!

Let me know your comments!

Thanks for the update! I'm running it for 24 hours now and it's still going strong.

[palmedia]

Still running (60 hours), I think my steak is ready now 😂 If it were up to me, this issue could be closed.

Thanks again!

[plmilord]

I'm going to remember that I shouldn't go eat steak at your place! 😂

...so I'm closing this issue! Thanks for following up on this!
