Huawei E3276 stops sending SMS until HA restart

[Morphy99]

The problem

I keep having issues sending SMS on my Huawei 4G dongle which is connected to my router. It will stop working with the following in the log:

Logger: homeassistant.components.huawei_lte.notify Source: components/huawei_lte/notify.py:63 Integration: Huawei LTE Error in logs: Could not send to ['tel-number']: 125001: Unknown

A restart of HA resolves this so I'm assuming it's an issue with the integration?

I've enabled debug logging for the integration so I'll wait and see when it goes wrong what that throws up...

What version of Home Assistant Core has the issue?

core-2024.1.6

What was the last working version of Home Assistant Core?

core-2024.1.6

What type of installation are you running?

I don't really want to share the whole debug log here but I can't see anything related anyway. Is there anything specific I should be looking for? One cause might be a lack of cell coverage and not being able to send the SMS. One of my automations calls the send SMS when the internet ping sensor stops in the hope that although data connectivity dies, cell coverage is still ok. I'll try disabling the sms side of that automation and see if it falls over again.

Error code 125001 is named ERROR_WRONG_TOKEN in the underlying huawei-lte-api library, so this could indicate something wrong with the session management.

If you get a backtrace in error logs when this occurs, could you share at least that?

[Morphy99]

Thanks for looking into it! I have debug logging enabled but there's no backtrace error just this:

[scop]

Does this happen every time sending an SMS is attempted, or does sending the message sometimes succeed?

[scop]

And to clarify, when this happens, does the integration stop working completely, or just the SMS sending part of it?

[Morphy99]

It seems to work after restarting HA then will stop working again after a few minutes. The other entities on the device are continuing to update so I assume it is just the SMS side.
