[SOLVED] Items: difference between "changed" and "received update"

Hello Community,
short question concerning rules:

What’s the difference between

when item xxxxx changed


when item xxxxx received update


Is there an explanation available somewhere in the documentation or here in the community threads?

Thanks and regards

Take a look at


There is a table, that has some explanation about it.
This should help you for a basic understanding. :slight_smile:

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.


Thank you!
