Can't get cameras to start recording with HA service call

[TheDK]

If I use

service: camera.aarlo_start_recording
data:
  entity_id: camera.aarlo_haustur
  duration: 30

I get this error:

2022-03-02 16:19:20 WARNING (MainThread) [homeassistant.util.async_] Detected blocking call inside the event loop. This is causing stability issues. Please report issue to the custom component author for aarlo doing blocking calls at custom_components/aarlo/pyaarlo/backend.py, line 153: r = self._session.post(

2022-03-02 16:19:20 WARNING (MainThread) [custom_components.aarlo.camera] failed to start recording for Haustur

If I use

service: aarlo.camera_start_recording
data:
  entity_id: camera.aarlo_haustur
  duration: 30

the camera signals "Recording" for a couple of seconds, then goes back to "Just been active" - but no recordings show up.

The request snapshot with camera.aarlo_request_snapshot works just fine.

Same thing, but requesting a snapshot with camera.aarlo_request_snapshot doesn't work.
