The integration makes HA unresponsive at night hours

[JuusoOikarinen]

I discovered that something happens (possibly related to the service providers servers) during the night hours that causes the HA-Nysse integration to make the entire HA instance very slow and unresponsive.

The phenomenon is very repeatable: every night around 22:30 (Finnish time) to approx 04:00 the phenomenon occurs, then goes away and everything works normally. The phenomenon causes everything in HA to perform sluggishly, including the browser interface, the REST API, automations, etc. Core sensors such as "sensor.home_assistant_core_cpu_percent" become "unavailable". If I this stage disable the HA-Nysse integration, all symptoms go away, like the click of a finger.

I have not really seen much related to this in the logs, except with the possibly related entries such as the ones below:

Detected that custom integration 'nysse' calls async_forward_entry_setup for integration, nysse with title: *****, which is deprecated, await async_forward_entry_setups instead at custom_components/nysse/__init__.py, line 18: await hass.config_entries.async_forward_entry_setup(entry, "sensor"). This will stop working in Home Assistant 2025.6, please create a bug report at https://github.com/warrior25/HA-Nysse/issues
