Detected blocking call to import_module in Home Assistant 2026.4

[meelis-gift]

Home Assistant logs this warning immediately after every restart/startup, while the Compit integration is being loaded:

Detected blocking call to import_module with args ('compit_inext_api.definitions',)
inside the event loop by custom integration 'compit'
at custom_components/compit/init.py, line 33:
connected = await connector.init()

Integration version: 2.0.0
Home Assistant Core: 2026.4.0
Installation type: Home Assistant OS
Python: 3.14

The integration still appears to work, but Home Assistant reports this as a blocking operation warning.

HA developer docs say imports inside the event loop should be moved to module-level imports or handled outside the event loop:

Additional observation: this warning seems to appear only once during Home Assistant startup/restart. I do not see it repeating during normal operation.

In my log it appears right after the custom integration is loaded:

2026-05-14 21:17:18 WARNING (MainThread) [homeassistant.util.loop]
Detected blocking call to import_module with args ('compit_inext_api.definitions',)
inside the event loop by custom integration 'compit'
at custom_components/compit/init.py, line 33: connected = await connector.init(

So it looks like the blocking import happens during integration initialization.
