SMA integration failed to connect to converter

[DrekiHeartz]

The problem

SMA solar will not connect to the inverter, when attempting to do so, the message "Failed setup, will retry" is shown.

With debugging for the SMA solar integration enabled, the following debug string is returned: DEBUG (MainThread) [pysma] Sending POST request to /dyn/login.json: {'data': '{"right": "usr", "pass": "##MYPASSWORD##"}', 'headers': {'content-type': 'application/json'}} After this, the connection has failed.

I have confirmed that my local IP address was and still is correct. No further changes were made to the settings.

I am having similar problems. In my case the communication to the PV-Inverters is ok. But the communication to the Battery-Inverter is damaged. The problem occurs since the last Core Update of Home Assistant to version 2024.2.2. I have attached the debug log as file. home-assistant_sma_2024-02-19T12-41-33.277Z.log

Unfortunately, I have noticed that my SB3.0 became unavailable again: SB3.0-1AV-XX XXX Status changed to Ok 16:41:50 - 2 days ago March 2, 2024 SB3.0-1AV-XX XXX Status became unavailable 02:07:24 - 3 days ago But it came online half day later; only i'm missing some sun data now.

Hello, after rebooting as @martijn1247812 experienced the connection problem was gone. But now, after updating to Core Hassio 2024.3.0 I once again lost the connection to my battery converter SBS3.7-10. The connection to my two other PV-Inverters (STP8.0-3AV-40, STP10.0-3AV-40) is as it should without any problem. I will now try to reboot once again the battery converter, but it should not be needed after every update.

The shown Error message in the log: Logger: pysma Quelle: components/sma/init.py:56 Erstmals aufgetreten: 09:30:57 (22 Vorkommnisse) Zuletzt protokolliert: 09:57:42

I think this isn't related to recent HA updates. I've been having these problems for at least a year. Could this be a problem that's related to sunnyboy converters having a limit in the amount of connections?

Its likely you have an integration blocking the event loop

1. Install profiler integration https://my.home-assistant.io/redirect/config_flow_start/?domain=profiler
2. Enable asyncio debug service as soon as possible after startup https://www.home-assistant.io/integrations/profiler/#service-profilerset_asyncio_debug
3. Watch logs for RuntimeError: Non-thread-safe operation and long asyncio delays
4. Download and post logs with full trace

For 2024.5.x and later Home Assistant debug mode can also be enabled in configuration.yaml

homeassistant:
  debug: true
