Hi. We’ve seen a lot of features added to automations, like loops, wait templates. This allow us to make really powerful and advanced automations, but unfortunately at the same time, those new functionalities render last_triggered attribute no longer sufficient. Same automation may take completely different time to execute depending on circumstances. Therefore we’re missing an attribute similar to last_triggered but pointing to time when the automation was finished. The added benefit of having last_completed attribute would be ease of calculating how long it took to execute the automation from within another automation.
