BlueSpray Irrigation Controller

Hi, I was wondering if anyone has integrated their home assistant with a BlueSpray irrigation controller.
They seem to have a JSON API with the local controller.

It would be great to be able to see when watering is / has occurred via HA and see the status of the rain sensor.
Bonus would be able to manually water or stop watering based on HA events.

In new to HA so want to see what is out there at the moment before I start looking into creating integrations.
