Hello,
Aarlo not working since 3 days, it has worked as a charm during some months except the last 3 days.
No events are updated, motion , battery, last event except if I reboot HA.
backend is set to sse configuration.
[pyaarlo] sseclient-error=ChunkedEncodingError is repeat every 30 sec.
I tried to reinstall integration, clear cache, modify config …
Test config on other instance of home assistant …
But no way …
Have you the same issue?
Thx
