You could use a delay node set to rate limit mode, once an hour, discard intermediate messages.

You probably have the delay node set to delay mode. It should be set to rate limit as explained by @Colin

1. Use a delay node.
2. Set it to "Rate Limit" mode.
3. One message per hour.
4. Drop intermediate messages.
