Hey there @ocalvo, mind taking a look at this issue as it has been labeled with an integration (sms) you are listed as a code owner for? Thanks!

I'm using a "Teltonika TRM240" as a modem if that information can be of any use, and it has been working fine in both receiving and sending SMS in Core 2021.6.6. ( https://teltonika-networks.com/product/trm240/ )

After sending an SMS I usually get the balance of the account back as an SMS from the service provider and it causes Home Assistant to crash.
I'm also using SMS to remotely do a check if my network is unavailable.

ocalvo · 2021-08-19T14:42:06Z

Can you paste the debug logs?

glith · 2021-08-19T14:53:26Z

Maybe silly question.. But how do I do that?
I did:

"logger:
default: debug"

However.. It deleted everything up until the restart. couldnt see anything before that.

glith · 2021-08-19T15:17:16Z

Did these:
logger:
default: info
logs:
homeassistant.components.sms.gateway: debug
homeassistant.components.sms.notify: debug

and tail -f homeassistant.log

And nothing is logged before the Core reboot when it receives the SMS.

glith · 2021-08-19T15:22:46Z

The supervisor log is writing this right after the crash.. Maybe normal at reboot?

Any progress in reproducing this?

Any progress in reproducing this?

I think I have. But very hard to tell without logs.

glith · 2021-09-04T15:32:27Z

Upgraded to core-2021.9.2 and the problem persists.

glith · 2021-09-11T09:32:50Z

Still same problem with core-2021.9.5

Is there anything I can do to assist? The logs are purged at each crash.

The fix is submitted but you need to wait until October

ocalvo · 2021-09-11T23:59:15Z

@balloob @pvizeli Can we include the fix in the next service release?

ocalvo · 2021-09-11T23:59:47Z

This should be closed by #54237

TazUk · 2021-09-19T14:47:16Z

Running 2021.9.7 (which includes #54237) in Docker on Ubuntu 18.04 using a Huawei USB Modem E220 (sim unlocked) this continues to be an issue.

Note: I have the GSM signal strength indicator enabled via the integration.

ocalvo · 2021-09-19T17:06:37Z

None of this suggests a problem with the SMS integration.
Do you have an event handler for incoming SMS?
Can you describe it?

TazUk · 2021-09-19T17:18:12Z

None of this suggests a problem with the SMS integration.
Do you have an event handler for incoming SMS?
Can you describe it?

I have an automation using the incoming sms event:

# receiving SMS messages
# data: phone, date, text
# log receipt, record datetime and act on specific valid triggers.
- id: sms_received
  alias: "SMS Received"
  mode: queued
  trigger:
    - platform: event
      event_type: sms.incoming_sms
  condition: []
  action:

it runs after the SMS is collected by polling after the crash / restart occurs.

I'm aware that nothing in the logs indicates the core issue , however the only time that I have this issue is when an SMS is received in any version after 2021.6.6 (which I remained on until today). I can replicate this at will simply by sending my system an SMS message, which is obviously less than ideal.

ocalvo · 2021-09-19T17:21:05Z

What is in the action?

Do you see any of the actions getting executed?

TazUk · 2021-09-19T17:27:10Z

The actions are executed after restart when the sms is collected.

TazUk · 2021-09-19T18:18:41Z

I've just quickly tested after :

Removing and re-adding the integration
Disabling signal strength.
HA (not the docker container) still restarts when sent an SMS
Whether the SMS is processed seems to depend on timings - in my last test the SMS was not successfully processed (presumably because of the restart and automations being unavailable)

I should have some time available to run some further tests tomorrow if there's anything in particular to look for with my limited knowledge. I wonder whether @glith is also seeing this on 2021.9.7 and whether there's some common hardware at play?.

TazUk · 2021-09-19T18:46:54Z

I've run one last final test using debug as the logger default and checked the log.1 file.
This shows nothing related to the crash after an SMS was sent at 19:28GMT, just what appears to be normal operations. The last few lines of this log are below.

I'm out of my depth here - this feels like it must be related to the docker change between 2021.6.6 and 2021.7.x but it is clearly tied to the receipt of an SMS.

I suspect that the gammu worker thread is crashing and then tearing down the entire python process.
@pvizeli Do you know how to enable diagnostics to observer if a python thread is crashing?

ocalvo · 2021-09-19T19:58:27Z

@TazUk just to clarify:

Does the GSM signal sensor works? If yes, what is the signal strength?, If not, what happens when you enable it?
While not sending any SMS, can you receive more than one SMS without crashing the core?

While not receiving any SMS, can you send more than one SMS without crashing the core?

Signal strength steady at 42% (consistent value over the last few weeks)
Any single received SMS causes a crash
Sending SMS functions normally (tested multiple messages one after the other).

Should not. Maybe a function from the external library calls exit(0) on an error or misleading handling. Maybe the dmesg will show you why it got killed ha host logs

That command isn't recognised when I run it within the container - I'm using HA Container in docker. Should I be running it within a particular path?

I have updated the docs to reflect that modem SIM800C does not work at the moment.

A positive change in 2021.9.7... I do now receive the SMS.. But core keeps crashing.

ha host logs from it happens:

SIGSEGV - means there is a pointer memory issue in the library

SIGSEGV - means there is a pointer memory issue in the library

@pvizeli It seems the core does not enable the python fault handler. Is there a reason why not?
This will help in this instance.

@glith Can you set the environment variable PYTHONFAULTHANDLER and try to run again?

ocalvo · 2021-09-23T03:22:25Z

I was able to repro this in my development environment. As suspected the ReadDevice() call is crashing the process. This is a bug in gammu. I will be following up with a new issue against gammu.
