This is a sprinkler system with zones and waterings.

A zone is an area that can be watered. It has an ID.

A watering is a scheduled event that consists of an ordered list of zones and how long to water them (durations). Duplicate zones are allowed.

So the API returns data like this:

```
GET /watering/123456
