Hello Community,
short question concerning rules:
What’s the difference between
when item xxxxx changed
and
when item xxxxx received update
?
Is there an explanation available somewhere in the documentation or here in the community threads?
Thanks and regards
Christoph
Take a look at
https://docs.openhab.org/configuration/rules-dsl.html#manipulating-item-states
There is a table, that has some explanation about it.
This should help you for a basic understanding.

The difference is, that “received update” will fire even if the status is the same. “Changed” only if really changed.
For example:
Temperatur sensors send value every 5min.
received update will trigger even if it is the same temperature, changed not.
