# RDZ PDC Heat Pump Monitor

A custom Home Assistant integration for monitoring and controlling RDZ PDC heat pumps via their embedded web interface.

![Heat Pump Dashboard Overview](assets/images/dashboard-overview.png)
*Dashboard overview showing heat pump status and controls*

## Features

- **Climate Control** - Thermostat entity for controlling heating/cooling water temperature
- **Water Heater Control** - Dedicated entity for domestic hot water (DHW) temperature control
- **Comprehensive Monitoring** - 12+ sensors for temperatures, setpoints, and runtime statistics
- **Status Indicators** - 10 binary sensors for operational states
- **Local Polling** - Direct communication with heat pump, no cloud dependency
- **Dashboard Included** - Pre-configured Lovelace dashboard YAML
