Hunter HPC-400 - 4-Station Base - Plastic Outdoor Wall Mount with Plug

The HPC combines the power of Wi-Fi-based irrigation management and the convenience of modular functionality into one next-generation controller. HPC helps contractors save time, save water, protect landscapes, and meet the demands of customers who want smart home solutions. In addition, it lets contractors continue using their Roam and Roam XL remotes for quick on-site management.

Among the controller's many robust features is Predictive Watering, which adjusts irrigation schedules based on local, real-time temperature, rainfall probability, wind, and humidity. A built-in milliamp sensor makes troubleshooting wiring issues easy. By adding a simple-to-install HC Flow Meter, users can receive notifications regarding leaking pipes or broken sprinklers. Users can also manage the controller from anywhere using a smartphone, tablet, or computer.

The HPC is EPA WaterSense approved. Hydrawise is also compatible with Amazon Alexa for convenient voice control to start, stop, and suspend irrigation.
