Rate limits

The Giraffe Cloud has various rate limits to prevent thousands of email alerts being sent out in short succession. These rate limits are managed per user.

Event Type	Rate Limit
PIR sensors	1 notification per minute
Wireless PIR sensors	1 notification per minute
Objection detection	1 notification per minute
All other event types	No rate limit

The way the system works internally is:

• when a notification is sent out to a user successfully, we set a cache key with an expiry date in the future (for example 1 minute)

• when we try and send a notification to a user, we first check if a cache key already exists for the type of notification.

• if a cache key exists, we discard the notification.

Note that rate limits for the ARC integration are slightly different. Please see the ARC integration page for more details.
