[heisenberg2980]

Bug report

Describe the bug

Device disconnects for hours/days randomly, and then it connects and works again for a while. This is the error displayed in the web interface while the issue is happening:

And this is the log from ESPHome:

Additional information

• used Hardware:
  • EspHoMaTriXv2 version: 2024.12.1

To Reproduce

Install ESPHome into the EspHoMaTriXv2 and let it run for some days

Expected behavior

Device shouldn´t disconnect.

   if (!this->is_connected()) {
      if (now - this->last_connected_ > this->reboot_timeout_) {
        ESP_LOGE(TAG, "No client connected to API. Rebooting...");
        App.reboot();
      }
      this->status_set_warning();
    }

The message from the log come from a "watchdog", there should be only one entry in the log and the device should reboot.
I don't think a change in EspHoMatriX could solve this problem. Is a hardware defect possible, that causes the error and blocks blocks the reboot?

I don't know.

[heisenberg2980]

@lubeda why do you think the device is not rebooting? There is a 15 minutes delay between messages, so I believe the device is actually rebooting, but it doesn´t connect to ESPHome after the reboot so it keeps rebooting every 15 minutes. But the logs from ESPHome shows that it's actually connected to the device, so I´m not sure what is going on.

[lubeda]

Ussually after a reboot, there are a lot more log-entries.
can you change the loglevel to debug?

logger:
  level: DEBUG

and try again. Does the history of home assistant show the device as unavailable before it reboots?

[lubeda]

This could also help the reason of the connection problem

api:
  # ...
  on_client_disconnected:
    - logger.log: "API client disconnected!"

[heisenberg2980]

Now the device has started to work again on its own and it´s completely back to normal (as usual).

While the device was not working it appeared as disconnected in HA:

I have added the on_client_disconnected to the API section to see if I get any extra info next time the issue happens

[heisenberg2980]

After adding the on_client_disconnected I restarted the device and the issue happened again, but I don´t see any extra lines in the logs:

[heisenberg2980]

I just saw a new warning, not sure what it means or if it´s relevant:
