Blocking call to sleep

[Tobbe82]

Got this in the log:
Detected blocking call to sleep inside the event loop. This is causing stability issues. Please report issue to the custom integration author for sungrow doing blocking calls at custom_components/sungrow/sensor.py, line 280: await sungrowclient.async_update()

I have the same error message with my Sungrow inverter (SH4.0RS)

Detected blocking call to sleep inside the event loop by custom integration 'sungrow' at custom_components/sungrow/sensor.py, line 280: await sungrowclient.async_update()
