Loading Integration Broke After Upgrading from 0.1.6 to 0.1.7/0.1.8 about alarmdotcom

[uvjustin]

Can you share your configuration.yaml?

[jpreiditsch]

Here you go, I've 'redacted' identifiable items

Note my config for the alarmdotcom is very very basic

• platform: alarmdotcom
  username: !secret alarmdotcom_username
  password: !secret alarmdotcom_password

Its an account that I use is a login that created just for HA. Permission is custom with the following permissions enabled

• Remote Arming

Oh, I was actually just looking for the alarm_control_panel section.
It's strange that your logs say
2020-12-15 12:48:13 WARNING (MainThread) [homeassistant.components.alarm_control_panel] Setup of alarm_control_panel platform alarmdotcom is taking over 10 seconds. 2020-12-15 12:48:13 WARNING (MainThread) [homeassistant.components.alarm_control_panel] Setup of alarm_control_panel platform alexa_media is taking over 10 seconds.
When the two platforms should be aarlo and alarmdotcom. Is everything else in your system working well?
Since you are using such a basic alarmdotcom config, I can't see why anything would change between version 0.1.6 and subsequent versions.

[jpreiditsch]

Everything else is working fine in my system.
I do normally see the same weird message about the alexa load.

Here's the snippet of the logs when I'm using 0.1.6 of the component

2020-12-15 12:58:02 WARNING (MainThread) [homeassistant.components.alarm_control_panel] Setup of alarm_control_panel platform alarmdotcom is taking over 10 seconds.

2020-12-15 12:58:03 ERROR (MainThread) [pyalarmdotcomajax.pyalarmdotcomajax] Can not load login page from Alarm.com

The main difference is that I don't see the platform load error log
Have any dependencies changed or was there something changed with that specific TypeError message at the bottom of the log. Perhaps the old version was more lenient to the deserialization??

The snipped from 0.1.6 looks like it just failed to log in.
With 0.1.8 it looks like it is partially logging in and then getting stuck.
Can you check that you can actually log in to the portal with that username? Some users have reported that their providers are requiring 2FA on the logins, and that's the main reason for the updates to the component in the past few weeks. Which ADC provider do you use?

[jpreiditsch]

I just quickly tried logging into ADC's web site with the credentials I use for the integration and it didn't request 2FA.

The provider is Telus

[uvjustin]

Did the integration ever work for you?
If not, it's possible Telus has a slightly different interface than the ones we've seen before. If you want me to look into it more, you can make a temporary login for me to have a look.
I've posted a PGP key here. You can post the encrypted login here or you can PM me on the HA community forum.
#21 (comment)

[jpreiditsch]

I've been using your version of the integration as long as the official integration was dropped. its been working flawlessly.
I currently have it working but only when I download the custom component from girhut at this commit

https://github.com/uvjustin/alarmdotcom/tree/190a59261020593ce2b347940f783ed454e2b4aa

It stopped working when I updated in Hacs a bit back, so I reverted to the one above. When yesterday's release came out I updated in hacs again and it broke. So I reverted to the above and it started to work. Its pretty easy for me to just swap out the custom component between head of master and the old commit cause it to break or work.
PM is coming your way

[uvjustin]

I just tried the login you sent me and was able to log in with no problems. What kind of HA install are you running and what version are you on?

[uvjustin]

For troubleshooting, you can try logging in with the library itself outside of HA using the following code (fill in your username and password):

from pyalarmdotcomajax import Alarmdotcom
import asyncio
import aiohttp


async def main():
  username="YOUR_USERNAME"
  password="YOUR_PASSWORD"
  async with aiohttp.ClientSession() as session:
    adc = Alarmdotcom(username,password,session,False,False,False,None)
    await adc.async_login()
    await adc.async_update()
  print(adc.state)
  print(adc.sensor_status)

loop = asyncio.get_event_loop()
loop.run_until_complete(main())

[uvjustin]

I see your config has several other files included at the bottom. Does one of those files have another alarm_control_panel: section? Can you check the configuration.yaml as instructed here? https://www.home-assistant.io/docs/configuration/troubleshooting/

[jpreiditsch]

2020.12.0 on a OS 5.8 Pi3 64 bit. This also occurred on 118.x I’ve updated the config to utilize the same permissions. If you want to try that. But I’ll also give the script a try and see what the difference is in them. I’ll let you know thanks for the assistance.

Check config always passes.
The additional files don’t define any integrations except for extracting my google assistant and Alexa configs out to their own files (their customization is longer than my main config :/)

[uvjustin]

It's still strange that there's an alarm platform named alexa_media in your logs.
Does the code snippet to test the library itself work on your system?

[jpreiditsch]

my pi isn't configured for root ssh access. I actually don't have pysical access to it at the moment. I never ended up getting the import settings to enable it before injuring my back.
I downloaded the alarmdotcomajax library and aio http 3.7.1 and latest beautifulsoup4 to my mac and ran the script with the credentials that I use and it returns the following.

disarmed
System OK, Back Door is Closed, Fire Detector is Not Reset, Front Door is Closed, Garage Door is Closed, Motion Detector is Idle, Motion Detector Basement is Idle, Upstairs Door Back is Closed, Upstairs Door Front is Closed

So it definitely seems to be environment related or something specific to how HA is making the request.
alexa_media is the latest version of the alexa media player from hacs. Maybe its trying to expose alexa guard as an alarm control panel.

maybe its not the underlying library itself but something in the integration code?

[jpreiditsch]

We'll see about compatibility but I'm going to try to utilize the older version with the updated alarmdotcomajax dependency for fun..

[jpreiditsch]

Yeah that change I made did not work lol I'll play around a bit more and let you know if I see anything

[jpreiditsch]

File "aiohttp/_http_writer.pyx", line 137, in aiohttp._http_writer._serialize_headers
File "aiohttp/_http_writer.pyx", line 109, in aiohttp._http_writer.to_str
TypeError: Cannot serialize non-str key None
Which makes me wonder why its trying to send none in the writer instead of a value

In the ajax config I see this

self._twofactor_cookie = (
            {"twoFactorAuthenticationId": twofactorcookie} if twofactorcookie else {}
        )

It almost looks like the component is trying to serialize a null value instead of not sending the parameter.

[jpreiditsch]

So I got it working in a really funny manner

Changed

  - platform: alarmdotcom
    username: !secret alarmdotcom_username
    password: !secret alarmdotcom_password
      

to

  - platform: alarmdotcom
    username: !secret alarmdotcom_username
    password: !secret alarmdotcom_password
    two_factor_cookie: ""

I played around in the component and found this by playing around a bit

Original

self._alarm = adc_class(
            username,
            password,
            websession,
            force_bypass,
            no_entry_delay,
            silent_arming,
            two_factor_cookie,
        )

changed it to

self._alarm = adc_class(
            username,
            password,
            websession,
            force_bypass,
            no_entry_delay,
            silent_arming,
            None,
        )

Which did not work
So I changed it to

self._alarm = adc_class(
            username,
            password,
            websession,
            force_bypass,
            no_entry_delay,
            silent_arming,
            "",
        )

And this did work.

So then I then reverted updated the config with the empty string and it worked fine.

Perhaps there is some other component pulling in a dependency that is causing the issue.

That's strange. I could easily change the config parameter to default to "" (I had actually previously considered doing so based on what is written here: https://developers.home-assistant.io/docs/development_validation/ , but that suggests just not specifying None explicitly as a default and doesn't say anything about always providing a default. If you look through the code base most usages of vol.Optional() don't specify defaults).
Anyway, it's not clear why using None should be an issue. That ternary line you posted is designed to receive a None and should set the variable to an empty dict. It looks like in your case it is evaluating the other way and returning a dict of {"twoFactorAuthenticationId": None}. No idea what is going on with that. I'll see if anyone reports something similar and whether we can find out what's happening.

Really reviewing the code there didn't seem to be anything wrong with it at all. It seems mostly environment or possibly a different version of the async io library included by another integration.
Possibly some additional explicit tightening of the conditions could be added... note I'm not a python expert at all but I can read and follow the code

Maybe change it up some how to not send the cookies parameter if None was passed in. It could be the serialization of the empty dictionary is handled differently. But yeah this is really strange.

Thanks again for the assistance on this. I've updated to the very latest release from hacs (I think you just updated the readme) but it still works with my goofy empty string for the two_factor_cookie

[uvjustin]

Haven't heard of any other reports on this yet so it's probably something related to your install. I think the Alexa component uses a custom aiohttp which handles cookies differently - there's a decent chance the issue here is related to that. Since you've found a workaround and there doesn't seem to be an obvious problem with this component, I'm closing this for now.

@uvjustin I've realized the issue only occurs when the home assistant log shows this after starting.
"Can not load system data from Alarm.com"

I think the refactoring of the async_login to into
_async_get_ajax_key
_async_get_system_info
Might have caused the issue to appear

async_system_info call might still be happening after failing to load the login page instead of just returning from async_login if async_get_ajax_key would have normally returned false.

If the _async_get_ajax_keydidnot work the values of the ajax headers would be

self._ajax_headers = {
            "Accept": "application/vnd.api+json",
            "ajaxrequestuniquekey": None,
        }

and the web call to

 async def _async_get_system_info(self):
        try:
            # grab system id
            async with self._websession.get(
                url=self.SYSTEMITEMS_URL, headers=self._ajax_headers
            ) 

Would still have the none value in the headers which corresponds to the stack trace with the error on line 160 that I first reported.

The issue only seems to happen if the login fails when first starting up preventing the component from loading.

[uvjustin]

You're right about the problem from refactoring. Thanks for pointing that out. I will fix that now.

[uvjustin]

Made the change, see if it fixes the issue on your end.

[jpreiditsch]

I've pulled in the update and so far so good. Its behaving. My HA is scheduled to restart every morning so we'll see.
The error was intermittent so it definitely was a tough one to track down.
Thanks for the fix.

[uvjustin]

Great. Thanks for digging in and tracking down the problem.
