It could be great if we would have the possibility to choose if an integration will throw or not an error when it is offline.
In my exemple I have 2 integration (a printer and an harmony hub) that are offline when they are not used.
But my logs are filled-up of connection error while I’m not using them which tend to hide real errors to be treated.
I bump up this topic, once again…
The most annoying thing with that is when the HA is restarting, it stays stuck couple of minutes (I guess until an access timeout) at :
homeassistant starting Logitech Harmony hub, not everything will be available until it is finished.
I’m still looking to exclude specific devices from the startup check; if someone has a workaround, it would be much appreciated
