NOTE: Development is in progress.

nilan2mqtt fetches Nilan (R) heatpump CTS700 readings and settings via modbus and sends them to MQTT broker in regular intervals. It also executes commands retrieved from MQTT. Compatible with Home Assistant.

• NILAN_ADDR - Nilan heatpump address, including port. E.g. 192.168.1.15:502
• MQTT_ADDR - Address of MQTT broker, e.g. "192.168.1.18:1883"
• MQTT_USER - (optional) MQTT broker username
• MQTT_PWD - (optional) MQTT broker password
