What happens if a device matches a trigger, but is offline?
When a device is offline, it will be added to the automation pipeline like normal. If an action requires direct interaction with the device, then the device will remain at that step until it comes online again. Then the action will proceed normally.
Can a device be added to the same automation multiple times?
An endpoint can only be active (running/queued) in an Automation ONCE per Trigger. This means if a device remains offline for an extended period (e.g., a week), the next scheduled trigger won't add it again if it's already in the pipeline.
